从番红花(crocus sativus L.)花粉中分到两个新苷,命名为番红花新苷甲(1)和乙(2).经理化性质和对它们的 IR、UV、~1HNMR、~(13)C NMR 和 MS 数据的分析,鉴定1为异鼠李素-4′-O-α-L-鼠李吡喃糖(1→2)β-D-葡萄吡喃糖苷,2为β-对羟基苯基-乙醇-α-O-α-L-鼠李吡喃糖(1→2)-β-D 葡萄吡喃糖苷.
Two new glycosides were isolated from pollen of crocus sativus L. and named as crocin (1) and B (2). The physicochemical properties and their IR, UV, ~ 1HNMR, ~ (13) C NMR and MS data identified 1 is isorhamnetin -4’-O-α-L-rhamnopyranose (1 → 2) β-D-glucopyranoside 2 is β-p-hydroxyphenyl-ethanol-α-O-α-L-rhamnopyranose (1 → 2) -β-D-glucopyranoside.
