Abstract:
OBJECTIVETo study the chemical constituents of ethanolic extract from herbs of Dicliptera chinensis.
METHODThe 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.
RESULTSeven 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).
CONCLUSIONAll the compounds except 6 were obtained from the plants of Dicliptera for the first time.
