摘 要 ：该文对辣椒Capsicum annuum果实进行化学成分研究,采用多种色谱技术(硅胶,Sephadex LH-20,MCI GEL CHP-20P,HPLC等) 分离纯化,根据波谱学数据(UV,IR,MS,1D-和2D-NMR) 进行结构鉴定.从辣椒果实中分离得到5个化合物,结构分别鉴定为辣椒黄酮苷A(1),尿苷(2),腺苷(3),7-羟基-6-甲氧基桂皮酸乙酯(4) 和7-羟基桂皮酸乙酯(5).其中,化合物1为新化合物,其化学结构为木犀草素-7-O-[2″-O-(5‘‘‘-O-芥子酰基)-β-D-芹糖]-β-D-葡萄糖苷,命名为辣椒黄酮苷A.化合物2~5为首次从该植物中分离得到.
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.
