[Abstract] To investigate the chemical constituents from Commelina communis， fifteen compounds were separated and purified by silica gel， Sephadex LH-20， and ODS column chromatography， and semi-preparative HPLC. By analyses of NMR and MS data as well as their physical and chemical properties， the structures of these compounds were identified as chrysoeriol-7-O-β-D-glucoside(1)， methyl gallate(2)， p-coumaric acid(3)， protocatechuic acid(4)， caffeic acid(5)， p-hydroxybenzoic acid(6)， 2-phenethyl-β-D-glycosidase(7)， rhaponticin(8)，(7S， 8R)-dihydrodehydrodiconiferyl alcohol-9-O-β-D-glucoside(9)， isovitexin(10)， isofurcatain(11)， isorhamnetin-3-O-β-D-glucoside(12)， quercetin-3-O-α-L-rhamnoside(13)， isoquercitrin(14)，and 1， 2-dihydro-6， 8-dimethoxy-7-1-(3， 5-dimethoxy-4-hydroxyphenyl)-N N2-bis-[2-(4-hydroxyphenyl)ethyl]-2， 3-naphthalene dicarboxamide(15). Compounds 2， 5-9， 11， 13 were obtained from the genus Commelina for the first time.
[Key words] Commelina communis； methyl gallate； protocatechuic acid； isovitexin； isofurcatain
