OBJECTIVE
To study the chemical constituents from the stems of Cudrania tricuspidata.
METHOD
The chemical constituents from the ethanol extract of C. tricuspidata were isolated and purified by silica gel, Sephadex LH-20 column chromatographic methods. Their structures were identified on the basis of spectroscopic data and physico-chemical properties.
RESULT
Thirteen compounds were isolated and identified as butyrospermyl acetate (1), glutinol (2), taraxerone (3), quercetin (4), kaempferol (5), isorhamnetin (6), orobol (7), 3'-O-methyorobol (8), taxifolin (9), naringenin (10), steppogenin (11), 1,3,6,7-tetrahydroxyx-anthone (12), 5,7-dihydroxy chromone (13).
CONCLUSION
Compounds 1-3, 6, 13 were isolated from this genus for the first time, while compound 12 was isolated from this plant for the first time and we firstly reported the terpenoids from the genus Cudrania.
目的
研究柘树茎的化学成分。
方法
采用硅胶柱色谱、葡聚糖凝胶LH - 20柱色谱等方法对柘树乙醇提取物中的化学成分进行分离纯化，并根据光谱数据和理化性质鉴定其结构。
结果
分离鉴定出13个化合物，分别为乙酸乳木果酯（1）、谷甾醇（2）、蒲公英赛酮（3）、槲皮素（4）、山柰酚（5）、异鼠李素（6）、紫铆因（7）、3'-O-甲基紫铆因（8）、紫杉叶素（9）、柚皮素（10）、蛇麻脂醇（11）、1,3,6,7 - 四羟基呫吨酮（12）、5,7 - 二羟基色原酮（13）。
结论
化合物1 - 3、6、13为首次从该属植物中分离得到，化合物12为首次从该植物中分离得到，且首次报道了柘树属的萜类化合物。
