A new phenolic compound from Crinum asiaticum L.

A new phenolic compound was isolated from the ethanol extract of the bulbs of Crinum asiaticum L.var.sinicum Baker.Its structure was defined as 1-（2-hydroxy-4-hydroxymethyl）phenyl-6-O-caffeoyl-β-D-gluco-pyranoside on the basis of spectroscopic evidences.

CRINISINE，A NEW ALKALOID FROM CRINUM ASIATICUM L．VAR．SINICUM （ROXB．EX HERB）BAKER

From the bulbs of Crinum asiaticum L. var. sinicum Bak., a new alkaloid, crinisine, has been isolated and characterized on the basis of comprehensive spectral analyses. Additionally, three known alkaloids, lycorine, powelline and ermine were also obtained.

文殊兰叶子化学成分及抗炎活性研究

本文对西双版纳傣药痹通剂的配方植物文殊兰的叶子进行了化学成分分离以及抗炎活性研究。通过色谱柱分离纯化,从文殊兰叶子的甲醇提取物中分离得到13个化合物,并运用现代波谱学技术分别鉴定为:7,4'-二羟基黄烷(1)、7,4'-二羟基-8-甲基黄烷(2)、杜鹃素(3)、stigmast-4-ene-3β,6β-diol(4)、byzantionoside B(5)、daucosterol+stigmasterol-3-O-glucopyranoside(6)、(6R,9R)-3-oxo-α-ionol-9-O-β-D-glucopyranoside(7)、5-hydroxy-6,7-methylenedioxy-2-methylchromone(8)、正丁基吡喃果糖苷(9)、豆甾醇(10)、豆甾醇苷(11)、β-谷甾醇(12)、胡萝卜苷(13),其中化合物2~8为首次从该植物中分离得到。文殊兰叶子提取物具有显著的NO抑制活性,即显著的抗炎活性,本次实验分离得到的化合物7,4'-二羟基-8-甲基黄烷(2)和杜鹃素(3)具有一定的抗炎活性。
