Isolation and structure identification of chemical constituents from Patrinia villosa

AimTo study the chemical constituents of Patrinia villosa Juss. MethodsSolvent extraction, silica gel column and preparative liquid chromatography were used to separate the chemical constituents, and the chemical structures were elucidated by physico-chemical properties and spectra data. ResultsEight compounds were isolated and identified as bolusanthol B (1), (2S)-5,7,2′,6′-tetrahydroxy-6,8-di (γ,γ-dimethylallyl) flavanone (2), orotinin (3), (2S)-5, 7, 2′, 6′-tetrahydroxy-6-lavandulylated flavanone (4), 3′-prenyl-apigenine (5), luteolin (6), quercetin (7) and apigenin (8). ConclusionCompound 2 and 4 are new compounds, compounds 1, 3 and 5 were separated from Patrinia genius for the first time, compounds 6, 7 and 8 were isolated from Patrinia vollosa Juss for the first time.
