ABSTRACT
OBJECTIVE: To study the chemical constituents of Whole Plants of Patrinia villosa (Thunb.) Juss. METHODS: Compounds were isolated by a combination of various chromatographic techniques including column chromatography over macroporous resin, Sephadex LH-20 and reversed-phase HPLC. Their structures were elucidated by physiochemical properties and spectral analysis. RESULTS: Nine compounds were isolated and identified as (E, 4R)-4-hydroxy-4, 5, 5-trimethyl-3-(3-oxobut-1-enyl)cyclohex-2-enone (1), vomifoliol (2), cis-4-hydroxymellein (3), dehydrovomifoliol (4), 3R, 5S, 6R, 7E, 9S-3, 5, 6, 9-tetrahydroxy-7-megastigmane (5), loliolide (6), 4-methoxybenzyl alcohol (7), sphenanthin A (8), and urea (9). CONCLUSION: Compounds 1-7 are isolated fromPatrinia genus for the first time.
