摘　　要：[目的]对须弥紫菀的化学成分进行研究。[方法]采用硅胶柱色谱进行分离,通过波谱分析方法鉴定化合物结构。[结果]从须弥紫菀石油醚-乙酸乙酯-甲醇萃取部位分离得到4个黄酮类化合物,分别鉴定为5,6二-羟基-2,7,3′,4′-四甲氧基黄酮醇(Ⅰ)、5,6二-羟基-2,7,4′-三甲氧基黄酮醇(Ⅱ)、Oxyayanin-B(Ⅲ)、木犀草素(luteolin)(Ⅳ)。[结论]这4个黄酮化合物首次从须弥紫菀中分离得到。[ Objective] The aim was to study the chemical constituents of Aster himalaicus [ Methods ] Compounds were separated by using silica gel column chromatography, and its structure was identified by using spectral analysis method. [ Resuh ] 4 kinds of flavonoid compounds from the petroleum ether-ethyl acetate-methanol extraction of Aster himalaicus, four compounds were identified as 5,6-dihydroxy-3,7,3＇ ,4＇-tetramethoxyflavonol（Ⅰ）, 5,6-dihydroxy-3,7,4＇-trimethoxyflavonol（Ⅱ）, Oxyayanin-B （Ⅲ） and luteolin（Ⅳ）. [ Conclusion] This is the first report on the chemical compound of Aster himalaicus, and the flavonoids were first isolated from this plant.
