Objective To study the chemical constituents from the whole plants of Patrinia villosa. Methods Chemical constituents were isolated and purified with the help of various chromatographic techniques such as silica gel, ODS, Sephadex-LH 20, Pre-HPLC. The structures of these compounds were identified by spectral data analysis. Results Twenty-eight compounds were separated from the ethanol extract of P. villosa, which were identified as nortrachelogenin (1), salicifoliol (2), pinoresinol (3), matairesinol (4), epipinoresinol (5), boehmenan (6), (+)-dehydrovomifoliol (7), (3S,5R,6S,7E)-3,5,6-trihydroxy-7-megastigmen-9-one (8), loliolide (9), 9-hydroxy-4,6-megastigmadien-3-one (10), scopoletin (11), caffeic acid ethyl ester (12), 5,7-dihydroxy l-4'-methoxyl flavonol (13), 7-ketositosterol (14), 5α,8α-epidioxyergosta-6,22-dien-3β-ol (15), stigmast-4-ene-6α-ol-3-one (16), stigmast-4-ene-3,6-diol (17), 2,2'-oxybis(1,4)-di-tert-butylbenzene (18), kaempferol (19), p-hydroxybenzaldehyde (20), 2'-O-(9Z,12Z,15Z-octadecatrienoyl) glyceryl β-D-galactopyranoside (21), protocatechualdehyde (22), p-coumaric acid (23), p-hydroxybenzoic acid (24), 5-hydroxy-4-(4-hydroxyphenyl)-2(5H)-furanone hydroxybutenolide (25), 6,7-dihydroxy-coumarin (26), chlorogenic acid (27), and methyl chlorogenate (28). Conclusion Compounds 1, 2, 4, 5, 6, 8, 10—26, and 28 are isolated from P. villosa for the first time.
