[Abstract] Five compounds were isolated from Capsicum annuum by means of various chromatographic techniques(silica gel，Sephadex LH-20，MCI GEL CHP-20P and HPLC)，and their structures were determined as luteolin-7-O-[2″-O-(5-O-sinapoyl)-β-D-apiofuranosyl]-β-D-glucopyranoside( 1)，uridine( 2)，adenosine( 3)，7-hydroxy-6-methoxy cinnamic acid ethyl ester( 4) and 7-hydroxy cinnamic acid ethyl ester( 5) by extensive spectroscopic analyses(UV，IR，MS，1D- and 2D-NMR). Among them，compound 1 is a new flavone glycoside named as capsicuoside A，and cmpounds 2-5 are isolated for the first time from the fruits of C. annuum.
[Key words] capsicuoside A； flavone glycoside； Capsicum annuum； Solanaceae
