摘　　要：通过溶剂萃取、硅胶柱色谱及凝胶色谱等分离手段从虎尾草Lysimachia Barys-tachys中分离得到6个化合物。经IR、NMR等波谱技术,确定其化学结构分别为:槲皮素、山奈酚、山奈酚-3-O-β-D-半乳糖苷、槲皮素-3-O-β-D-葡萄糖苷、β-谷甾醇、β-胡萝卜苷。其中化合物山奈酚-3-O-β-D-半乳糖苷、槲皮素-3-O-β-D-葡萄糖苷、β-胡萝卜苷为首次从该植物中分离得到。Six compounds were isolated by using solvent extraction,silica gel column chromatography and gel chromatography from Lysimachia barystachys.Their structures were identified as following based on IR and NMR spectrum： quercetin,kaempferol,kaempferol-3-O-β-D-galactopyranoside,quercetin-3-O-β-D-glucopyranoside,β-sitosterol,anddaucosterol.Kaempferol-3-O-β-D-galactopyranoside,quercetin-3-O-β-D-glucopyranoside,anddaucosterol were isolated for the first time from this plant.
