Isolation and structure identification of chemical constituents from Patrinia villosa / 药学学报

ABSTRACT

<p><b>AIM</b>To study the chemical constituents of Patrinia villosa Juss.</p><p><b>METHODS</b>Solvent 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.</p><p><b>RESULTS</b>Eight compounds were isolated and identified as bolusanthol B (1), (2S)-5, 7, 2', 6'-tetrahydroxy-6,8-di (gamma,gamma-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).</p><p><b>CONCLUSION</b>Compound 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.</p>
