摘要
红树林中的秋茄Kandeliacandel叶乙醇萃取物,经大孔离子交换树脂DA201吸附柱色谱,聚酰胺柱色谱分离,甲醇反复结晶,得浅黄色针状结晶。1HNMR,13CNMR,UV和IR分析,确定了该结晶化合物为卢丁,其分子式为C27H30O16,分子量为610.51。
The extract of Kandelia candel leaves from Danzhou, Hainan Province by 60% ethanol was chromatographed first by a column with macropore ion exchange resin DA201, and then, by a column with polyamine. A yellow fraction was collected and crystalized repeatedlyfor four times in methanol. A light yellow needle crystal compound with melting point of 188-190℃ was identified structurally by IR, UV, 1H NMR,13C NMR as rutin, one of flavonoid compounds . The molecular formular of rutin is C27H30O16 and its molecular weight is 610.51.
