Abstract
New carotenoids 1 and 2 were isolated as minor components from the ripe fruits of paprika (Capsicum annuum). The structures of 1 and 2 were determined to be (3R,5'R)-3-hydroxy-beta,kappa-caroten-6'-one and (5'R)-3,4-didehydro-beta,kappa-caroten-6'-one, respectively, from UV-vis, NMR, CD, HRFABMS, and FABMS/MS spectra.
摘要
新类胡萝卜素1和2是从红辣椒（辣椒属）的成熟果实中作为次要成分分离得到的。通过紫外可见光谱、核磁共振光谱、圆二色光谱、高分辨快原子轰击质谱和快原子轰击串联质谱，确定1和2的结构分别为(3R,5'R)-3-羟基-β,κ-胡萝卜素-6'-酮和(5'R)-3,4-脱氢-β,κ-胡萝卜素-6'-酮。
