Abstract:

Three iridoid glycoside compounds were purified and isolated from leaves of Lonicera japonica Thunb. (L. japonica) with silica gel, sephadex LH-20 and preparative HPLC. Through analysis of spectrum data and physicochemical properties, we identified them as secoxyloganin, demethylsecologanol, secologanin,β-sitosterol  and daucosterol.Compound demethylsecologanol  is originally isolated from Lonicera.

Key words: leaf of Lonicera japonica Thunb., iridoid glycosides, demethylsecologanol, separation
