Objective To study the chemical constituents from the roots of Kadsura longipedunculata. Methods The constituents were isolated and purified by various chromatographic methods, and the structures were elucidated by spectroscopic analysis. Results Sixteen compounds were isolated from the roots of K. longipedunculata and the structures were identified as pinobatol (1), leptolepisol B (2), 7S,8R-erythro-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (3), 2,3-bis-(α-hydroxy-4-hydroxy-3-methoxybenzyl)-butane-1,4-diol (4), (7'S,8R,8'S)-4,4',9-trihydroxy-3,3',5-trimethoxy-9'-O-β-D-xylopyranosyl-2,7'-cyclo-lignan (5), aviculin (6), ent-isolariciresinol (7), lawsorosemarinol (8), (+)-anwulignan (9), isolariciresinol-2α-O-β-D-xyloside (10), procyanidin B3 (11), prodelphinidin B3 (12), (-)-gallocatechin (13), (+)-catechin (14), abscisic acid-β-D-glucopyranosyl ester (15), and (-)-oleuropeic acid 8-O-β-D-glucopyranoside (16). Conclusion Compounds 1-8, 11-13, 15, and 16 are isolated from the plants of Kadsura Kaempf. ex Juss. for the first time.
