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)-beta-D-apiofuranosyl]-beta-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.
