摘要
Aim Isolation and structural elucidation of the constituents from the aerialpart of Hypericum perforatum L. Methods Column chromatography and TLC were used to isolate chemicalconstituents. Physico-chemical characterization and spectroscopic analysis were employed forstructural identification. Results Three flavonols were isolated and identified. Conclusion Compound1 is a novel natural product and its structure has been characterized to be 3, 5, 7-trihydroxy-3',4'-isopropyldioxy-flavone.
目的 分离鉴定贯叶连翘 (HypericumperforatumL .)的化学成分。方法 通过硅胶柱色谱 ,sephadexLH 2 0分离纯化 ,根据理化常数和光谱分析鉴定结构。结果 自贯叶连翘地上部分中分离得到 3个黄酮类化合物。结论 化合物 1为新的天然产物 ,结构为 3,5 ,7 三羟基 3′,4′
