摘要

摘要:采用甲醇浸渍法从帝王拿破仑种子中分离出果皮。用正己烷和二氯甲烷对粗甲醇提取物进行分馏，得到正己烷馏分(11.01 g)、二氯甲烷馏分(35.16 g)和甲醇馏分(101.75 g)，对二氯甲烷馏分进行层析和纯化，得到化合物，并用一维和二维核磁共振(NMR)实验对其结构进行了表征。分离得到的化合物经鉴定为糖基化的豆甾醇。

Glycosylated stigmasterol from the rind of Napoleonaea imperialis

Abstract Napoleonaea imperialis rinds were separated from the seeds and extracted via maceration using methanol. The crude methanol extract was partitioned with n-hexane and dichloromethane to yield n-hexane fraction (11.01 g), dichloromethane fraction (35.16 g) and methanol fraction (101.75 g). Dichloromethane fraction was chromatographed and purified to give a compound whose structure was elucidated using one-dimension and two-dimension nuclear magnetic resonance (NMR) experiments. The isolated compound was characterized as glycosylated stigmasterol.
