The chemical constituents of Periploca forrestii were studied by means of macroporous resin, silica gel, ODS column chromatography and PHPLC. Nine compounds were isolated from this plant. By using ESI-MS and NMR, the structures of the nine compounds were determined as scopoletin (1), trans-3, 4-methylenedioxycinnamyl alcohol (2), syringaresinol (3), syringaresinol 4-0-beta-D-glucopyranoside (4), 6'-0-(E)-feruloylsucrose (5), loliolide (6), 4-hydroxy-3-methoxyl-benzaidehyde (7), delta5-pregnene-3beta, 17alpha, 20alpha-triol (8) and delta5-pregnene-3 beta, 17alpha, 20 alpha-triol-20-0-beta-D-canaropyranoside (9), respectively. Compounds 1, 2 and 5-7 are isolated from Periplocagenus for the first time.
