OBJECTIVE
To study the chemical constituents of the leave of Paulownia tomentosa.
METHODS
The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.
RESULTS
The compounds were identified as apigenin(I), uteolin(II), homoeriodictyol(III), 3alpha-hydroxyurs-12-en-28-oic acid (IV),3beta,19alpha-dihydroxyurs-12en-28-oic acid (pomolic acid)(V),2alpha,3a-dihydroxyurs-12-en-28-oic acid(VI),ursolic acid (VII),2alpha,3beta-dihydroxyolean-12-en-28-oic acid (maslinic acid) (VIII), daucosterol(IX),beta-sitosterol(X).
CONCLUSION
The compound I-X are obtained from the leave of Paulownia tomentosa (Thunb.) Steud for the first time.
目的
研究毛泡桐叶的化学成分。
方法
采用柱色谱法分离化合物，并通过光谱分析阐明其结构。
结果
所分离得到的化合物分别鉴定为芹菜素（I）、木犀草素（II）、高圣草酚（III）、3α-羟基乌苏-12-烯-28-酸（IV）、3β,19α-二羟基乌苏-12-烯-28-酸（委陵菜酸）（V）、2α,3α-二羟基乌苏-12-烯-28-酸（VI）、熊果酸（VII）、2α,3β-二羟基齐墩果-12-烯-28-酸（山楂酸）（VIII）、胡萝卜苷（IX）、β-谷甾醇（X）。
结论
化合物I-X首次从毛泡桐（Thunb.）Steud的叶中获得。
