在室温下,以甲醇提取胶东卫矛(Euonymus kiautschovicus)的新鲜果实,粗提取物经真空浓缩后,用石油醚和水分配提取。有机层经蒸干后上酰胺柱,以甲醇-水混合物洗脱。甲醇-水(1:1)洗脱部分经制备型TLC进一步纯化,用环己
The fresh fruit of Euonymus kiautschovicus was extracted with methanol at room temperature. The crude extract was concentrated in vacuo and extracted with petroleum ether and water. The organic layer was evaporated to dryness on an amide column and eluted with a methanol-water mixture. The methanol-water (1:1) fraction was further purified by preparative TLC using cyclohexanol
