OBJECTIVE: To study the chemical constituents of ethanolic extract from herbs of Dicliptera chinensis. METHOD: The compounds were separated by silica gel column chromatography, preparation TLC and reverse phase HPLC, their structures were identified by the spectroscopic methods of UV, NMR and MS. RESULT: Seven compounds were isolated from ethyl acetate extract. Their structure were identified as octasulphur (1), secoisolariciresinol dimethyl ether diacetate (2), 5-methoxy-4, 4'-di-O-methyl secolariciresinol (3), chinensinaphthol methyl ester (4), loliolide (5), beta-sitosterol 3-O-beta-D-glucopyranoside (6) and stigmasterol 3-O-beta-D-glucopyranoside (7). CONCLUSION: All the compounds except 6 were obtained from the plants of Dicliptera for the first time.
