Abstract: In order to optimize the preparation technology of inclusion of volatile oil from Asarum by β-cyclodextrin, the inclusion rate of methyleugenol, yield and drug loading rate in volatile oil from Asarum were taken as indicators, the technological conditions of inclusion of β-cyclodextrin were optimized by orthogonal tests, and the content of methyleugenol was determined by HPLC. The results showed the optimum inclusion process was that: volatile oil volume(mL):β-CD quality(g)was 1:6, inclusion temperature was 60 ℃ and inclusion time was 1 h.The inclusion of methyleugenol rate, drug loading rate and inclusion complex yield were 74.64%, 8.72% and 77.23% respectively. The optimized inclusion process was simple, stable and suitable for industrial production.

Key words: volatile oil from Asarum, methyleugenol, β-CD, inclusion process, orthogonal tests, HLPC
