OBJECTIVE
To investigate the chemical constituents of Desmos chinensis.
METHOD
Various column chromatographic techniques were employed for the isolation and purification of constituents from the ethanol extract. The structures were elucidated by spectral analysis.
RESULT
Eleven compounds were isolated and identified as lawinal(1), desmosal(2), desmethoxymatteucinol(3), unonal(4), isounonal(5), desmosflavone(6), allantoic acid(7), succinic acid(8), daucosterol(9), beta-sitosterol(10) and stearic acid(11). The structures of compounds 1 and 2 were reconfirmed by NOEDS technique.
CONCLUSION
Compound 2 is a new natural product and 7, 8 and 9 were found from this plant for the first time.
目的
研究假鹰爪的化学成分。
方法
采用多种柱色谱技术从乙醇提取物中分离纯化成分。通过光谱分析阐明其结构。
结果
分离鉴定出11种化合物，分别为罗勒烯醛（1）、去甲氧基鹰爪甲素（2）、去甲氧基马特西诺醇（3）、乌诺内酯（4）、异乌诺内酯（5）、去甲氧基鹰爪黄酮（6）、尿囊酸（7）、琥珀酸（8）、胡萝卜苷（9）、β-谷甾醇（10）和硬脂酸（11）。通过NOEDS技术重新确定了化合物1和2的结构。
结论
化合物2是一种新的天然产物，化合物7、8和9首次从该植物中发现。
