Ginsenosides are important chemical components of Panax quinquefolius L. and are closely related to its pharmacological activities. In this study, ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS) was used for high-throughput analysis of ginsenosides in the roots, leaves, and seeds of Panax quinquefolius L., leading to the identification of 72 ginsenosides across these parts. Both univariate and multivariate analyses revealed significant differences in the content and types of ginsenosides among the different plant parts. Based on statistical significance (p<0.05) and biological significance (fold change>4), 23 differential saponins were identified in the roots vs. leaves comparison, 26 in the roots vs. seeds comparison, and 27 in the leaves vs. seeds comparison. Content analysis revealed that the total amounts of Rg1, Re, and Rb1 in the leaves and roots were roughly equivalent and higher than in the seeds, while most other ginsenosides were more abundant in the leaves and roots than in the seeds. The pseudo-ginsenoside F11, which is unique to Panax quinquefolius L., was most abundant in the leaves, whereas acetylated pseudo-ginsenoside F11 was most abundant in the roots. 20(S)-Ginsenoside Rh1, acetylated ginsenoside Rg1, and quinquenoside IV were all significantly different among the three parts and could serve as markers for differentiation. This study reveals distinct ginsenoside profiles in the roots, leaves, and seeds of Panax quinquefolius L., providing technical support for its efficient development and utilization.
This study investigated the effects of direct-contact ultrasonic vacuum drying on the drying characteristics and quality of dandelion. Dandelion samples were dried under different ultrasonic power levels and compared with samples processed via vacuum freeze-drying, shade drying, and hot-air drying in terms of color, flavonoid content, and cichoric acid content. Results showed that the drying rate increased with increasing ultrasonic power and drying temperature. The Page and Two-term models provided the best fit for the drying kinetics. The color of samples dried via direct-contact ultrasonic vacuum drying at 192 W was closest to that of fresh samples among all considered methods. At 192 W, the flavonoid content in the solution after rehydration was significantly higher than that obtained using other drying methods(p<0.05). In addition, total flavonoid and cichoric acid contents at 192 W were 57.09 and 12.35 mg/g, respectively. Furthermore, comprehensive evaluation using the entropy weight-grey relational analysis method showed that the samples dried at 192 W exhibited the highest correlation degree and ranked first overall among all drying methods. This study confirms that direct-contact ultrasonic vacuum drying can effectively improve the drying characteristics and quality of dandelion, providing references for applications in food and traditional Chinese medicine.

Compared with the selective adsorption capacity of the NCOF to the analogs of chlorogenic acids, the MCOF showed higher selectivity to a family of related molecules with a structure similar to that of chlorogenic acids. This study shows that the MCOF provides an innovative opportunity to develop a highly selective material for the extraction and separation of a family of molecules from a high polarity medium.
A comprehensive quantitative model that evaluates Ganoderma lucidum as a medicinal material was established based on polysaccharides and entropy-weighted technique for order preference by similarity to ideal solution(TOPSIS) to provide a reference for the quality evaluation of G. lucidum as a medicinal material and selecting the best batches. Initially, the yield, sugar composition, total sugar content, protein content, and uronic acid content of crude polysaccharides were determined formultiple batches of G. lucidum medicinal materials from the same origin. Subsequently, the data were nondimensionalized. Finally, entropy-weighted TOPSIS was used to comprehensively evaluate the quality of G.lucidum polysaccharides from different batches to establish the optimal standard. The yield, component content detection, and cluster heat map analysis of the polysaccharides showed that the polysaccharide yield and the total sugar and uronic acid content of G. lucidum medicinal materials from different batches varied significantly, whereas differences in the sugar composition and protein content were relatively minor. Polysaccharide yield and intrinsic indicators of the G. lucidum medicinal materials were not related to their origin. Entropy weight analysis showed that the polysaccharide yield weight coefficient was the largest at 23.68%, followed by total sugar at 21.35% and uronic acid content at 13.24%. The TOPSIS ranking and grouping results showed that cultivated G. lucidum fruiting bodies and red G. lucidum polysaccharides had better comprehensive scores. The quality of G. lucidum medicinal materials differ widely among different batches from the same origin. Entropy-weighted TOPSIS based on multi-index comprehensive evaluation achieved rapid, efficient, and accurate optimization of the source for G. lucidum polysaccharide extractasa medicinal material and has broad application prospects in production and comprehensive quality evaluation. This study provides a reference for the quality evaluation of other Chinese medicinal and decoction materials.

Identifying potential antiepileptic active ingredients in Rhizoma Gastrodiae is of immense significance for the prevention and treatment of epilepsy. In this study, we used a larval zebrafish epilepsy model to evaluate the antiepileptic activity of Rhizoma Gastrodiae from two different regions. In addition, we employed metabolomics technology based on liquid chromatography tandem mass spectrometry/QE plus to detect the ingredients in Rhizoma Gastrodiae and performed pattern analysis to identify key differential metabolites. The metabolites were further identified using primary and secondary mass spectrometry data and literature references. This step was followed by the confirmation of their antiepileptic activity using the zebrafish epilepsy model. The results showed that nine extracts of Rhizoma Gastrodiae significantly reduced the number of whirls in zebrafish, and significant differences in antiepileptic activity were observed between the Rhizoma Gastrodiae samples from the two regions (P<0.05). Metabolomics and pattern analysis identified six important differential metabolites (Parishin E, Gastrodin, Parishin C, Parishin D, N6-p-hydroxybenzyl adenosine, and 4,4'-dihydroxydibenzyl ether). Activity verification results showed that Parishin E, Gastrodin, and N6-p-hydroxybenzyl adenosine significantly inhibited zebrafish epilepsy-like behavior.

Ultra-high performance liquid chromatography-Q Exactive hybrid quadrupole-orbitrapmass spectrometry (UPLC-Q-Orbitrap MS) was used with 0.05% formic acid water (A)-0.05% formic acid acetonitrile (B) as mobile phase gradient elution. The sample data were collected in positive- and negative-ion modes. The metabolites and metabolic pathway of rutin in rats were determined via high resolution extraction ion chromatography in the parallel reaction monitoring mode, combined with chromatographic retention time, accurate mass measurement and diagnostic ions.Twenty-nine rutin metabolites were detected and identified in positive and negative ion modes,and their main metabolic pathways were methylation, glucuronidation, sulfation and their compound reaction. The study provided the overall metabolic profile of rutin, which will provide a reference for further pharmacodynamic evaluation, development, and utilization in the future and offer a comprehensive research method for drug metabolism identification.
The aim of this study was to investigate the mechanism of action of Sanhuang Xiexin Decoction in the treatment of Alzheimer's disease (AD) using a network pharmacology approach. The active ingredients and targets of the Sanhuang Xiexin decoction were examined and screened using the systematic pharmacology database and the analysis platform of traditional Chinese medicine. AD-related targets were retrieved and screened through Gene Cards database, and drug and disease intersection targets were obtained through through Venn diagram.The STRING database was used to obtain the network information of protein-protein interaction (PPI). The Cytoscape was used to construct drugs-active ingredients-target-disease network and PPI,and DAVID database was used to analyze common targets in gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG). Furthermore, the Sybyl-x 2.1.1 software was used for molecular docking validation. The screening yielded 47 active ingredients and 71 related targets. Herein,the main active ingredients were quercetin, β-sitosterol, wogonin, baicalein, rivularin, and moslosooflavone; and the core targets were IL-6,TNF,IL-1β,VEGFA,TP53.The GO function enrichment analysis predominantly involved biological processes including drug response, hypoxia response, positive regulation of cell migration,and positive regulation of nitric oxide biosynthesis.KEGG analysis mainly involved pathways such as cancer pathways, HIF-1 signaling pathways, and TNF signaling pathways.Molecular docking results showed the presence of a relatively strong binding ability between the core target and the core compounds, such as β-sitosterol and rivularin.This study preliminarily explained that the Sanhuang Xiexin Decoction can interfere with AD by modulating HIF-1, TNF, and other signaling pathways, thereby inhibiting Aβ aggregation and tau phosphorylation, blocking acetylcholinesterase activation, and suppressing inflammation.
This study aimed to devise a methodology for the simultaneous determination of the contents of nine primary components in Lonicerae japonicae flos through ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The chemometric analysis of the nine primary components was performed via negative ion scanning. Further, chromatographic separation was performed on a Thermo Hypersil GOLD column at a temperature of 35 ℃. The mobile phase comprised methanol and water containing 0.2% formic acid, as determined through the cluster thermogram and principal component analyses of Lonicerae japonicae flos. The peak areas with concentrations of nine components exhibited a good linear relationship (R2>0.999 1), and the intraday (0.96%~2.26%) and interday (0.52%~3.04%) precisions and stability values (0.85%~2.15%) agreed well with relative standard deviation (RSD). The recovery rate was between 96.77% and 101.94%, and the RSD was between 2.48% and 4.01%. The results of the chemometric, hierarchical cluster, and principal component analyses revealed that there were considerable differences in the contents of the active ingredients of Lonicerae Japonicae Flos from various regions, and 3-O-caffeoylquinic acid and 3,5-dicaffeoylquinic acid were considered as the dominant compounds. UPLC-MS/MS quantitative and chemometric analyses of Lonicerae Japonicae Flos performed herein may provide a reference for the modernization of and innovative research on the effective ingredients of Lonicerae Japonicae Flos and related quantity effect relations as well as the quality control of related products.
To explore the effect of different slicing methods on the drying characteristics of Salviae Miltiorrhizae Radix Et Rhizoma, the hot air drying at 40 ℃ and traditional air drying at room temperature were performed and the results were compared. Furthermore, the effect of different slicing methods (circular cutting and 45° oblique cutting) and slice thickness (2, 4, and 6 mm) on the drying characteristics of Salviae Miltiorrhizae Radix Et Rhizoma were investigated. Several water-loss kinetic models were adopted to quantitatively describe the drying characteristics. Results showed that the drying was mainly a falling rate period. The drying rate decreased with the decrease of the moisture content of the dry basis. Furthermore, the larger the slice thickness, the lower the drying rate and the longer the drying time. According to statistical parameters, the Page model predicted and described the drying process more accurately than others. The predicted value of the model was in good agreement with the experimental value, and it could well describe the drying process for different slicing methods. The research provides a guidance for further investigating Salviae Miltiorrhizae Radix Et Rhizoma.

The mathematical formula for calculating the value of the feeding standard was developed, and the mode of quality risk management in traditional Chinese medicine preparations was constructed. The contents of peucedane A and peucedane B in three preparations containing Peucedani Radix (eight batches from four manufacturers) were determined using high-performance liquid chromatography; the feeding standard values were calculated; and the quality risks of the preparations were evaluated. The quality risks of preparations were divided into four categories based on the value of the feeding standard, allowing for an effective evaluation of the risks of preparations. The established method can be used to evaluate the standardization of preparation feeding and detect quality risks in real time, providing a decision-making basis for risk classification management.
This study aimed to provide a basis for the evaluation of germplasm resources, variety classification and identification, and selection of excellent varieties for Lonicera japonica based on submicroscopic structure characteristics of pollen grains. Optical microscope and scanning electron microscope were used to classify and identify the plants, stems, leaves, flowers, pollens, and outer ornamentations of L. japonica varieties. The data were analyzed using statistical product and service solutions(SPSS). There were certain differences in the morphological traits, pollen shapes, germinal apertures, and outer ornamentations of the eight L. japonica varieties. The stem and crown of the Sijihua plants were obvious, and the Beihua No.1 plants were bush-like. The buds of L. japonica No. 24 were sparsely pubescent. The pollen grains were spheres, with dense thorn-like ornamentations on the outer wall. The pollen grains of Beihua No.1 and Sijihua were triangular spheres, with dense, thick, thorn-like ornamentations on the outer wall. The stems, branches, and buds of Damaohua had dense, long pubescence. The buds of L. japonica No. 16 were densely covered, with glandular hairs and acicular hairs. The pollen grains of L. japonica No. 1, L. japonica No. 15, and L. japonica No. 23 were blunt triangular spheres or spheroids, with sparse, thorn-like ornamentations on the outer wall. The morphological characteristics of the pollen grains of L. japonica varieties provide a palynological basis for variety classification and identification.
To study the pilot-scale purification process and bacteriostatic effect of hypocrellin during the pilot-scale production, we extracted hypocrellin using different solvents and extraction methods. Then, we investigated the purification effects of the hypocrellin using salting-out, physical cooling, and ultrafiltration methods. The results showed that the amount of hypocrellin extracted using the jet pulverization method could reach up to 21.4 mg/g, and its density could exceed 90% after its purification via ultrafiltration. The analysis of the bacteriostatic activity of hypocrellin showed that it had good thermal stability and inhibitory effects against Escherichia coli and Candida albicans. We found that hypocrellin has natural antibacterial properties and good thermal stability, is easy to extract and purify, and can be used as a bacteriostatic drug in medicine and other applications.

In pH-ZRCCC,ethyl acetate-acetonitrile-water (4:1:5, V/V) was selected as the solvent system, trifluoroacetic acid (10 mmol/L) was added to the upper phase as the stationary phase, and ammonia (10 mmol/L) was added to the lower phase as the mobile phase. Caffeic acid (60.2 mg with a purity of 98.1%), p-hydroxycinnamic acid (6.3 mg with a purity of 98.8%), and mixture A (590 mg) were separated from 1.6 g of crude ethyl acetate extract of Herba Taraxaci. After further using HSCCC, petroleumether-ethyl acetate-methanol-water (1:4:1:4, V/V) was selected as the solvent system.Consequently, 1-O-caffeoylglycerol (7.7 mg with a purity of 82.2%), 3,4-dihydroxyphenylacetic acid (5.4 mgwith a purity of 24.8%), protocatechuic acid (6.2mg with a purity of 95.3%) and p-hydroxyphenylacetic acid (3.4 mgwith a purity of 89.0%) were obtained from 400 mg of mixture A.The method has a large preparation volume and good reproducibility, and is suitable for the separation and purification of Taraxaci Herba polyphenol compounds.
The study’s aim was to obtain Ginkgo biloba extract with a high mass fraction of total flavonoids. On the basis of single-factor test, the sample concentration, ethanol volume fraction, eluate volume, and elution flow rate were used as the investigation factors and the mass fraction and yield of total flavonoids extracted from G. biloba were used as the investigation indicators. Box-Behnken design (BBD) and response surface method were used to optimize the column chromatography process for purifying the total flavonoids extracted from G. biloba. Optimal purification was achieved by using a sample concentration of 3.1 mg/mL, ethanol volume fraction of 71%, eluate volume of 2 BV (BV is the column void volume), and elution flow rate of 2 BV/h. Under the optimal conditions, three batches of verification experiments were conducted. The average mass fraction of total flavonoids in the G. biloba extract reached 35.77%, and the yield was 93.30%. The mass fraction of total lactones in the G. biloba extract reached the standards of The Pharmacopoeia of the People's Republic of China. Using BBD and response surface method for optimizing the column chromatography process for the purification of total flavonoids is scientific, reasonable, and feasible.This study can be used as a reference for the industrial production of total flavonoids.
To determine the most optimal extraction process for angelica volatile oil and its antioxidant activity.
