贵州苗药对坐叶的化学成分预试分析

Prilliminary test of chemical components for Hedyotis uncinellaHooK. et Arn in Guizhou

首次对贵州苗药对坐叶的石油醚9、5%乙醇、水提取物进行预试分析研究,通过多种指示剂和显色剂的显色反应或沉淀反应,初步推断对坐叶中可能含有的化学成分。结果显示:对坐叶中可能含甾体、三萜、挥发油、油脂、黄酮、酚、强心苷、香豆素、内酯、糖、多糖、皂苷、糅质、有机酸等化学成分。此试验为进一步研究对坐叶的生物活性成分奠定了基础。

The paper studies the chemical constituents of Hedyotis uncinella HooK. et Am in Guizhou through preliminary test from petroleum ether, 95% ethanol and purified water. The chemical constituents of Hedyotis uncinella HooK. et Arn was primarily demonstrated by precipitation reaction or color reaction with various indicator. Results： Hedyotis uncinella HooK. et Am may contain chemical constituents such as steroid, tfiterpenoids, volatile oil, fat, flavone, cardiacglycoside, coumarin, lactone, sugar, polysaccharide, saponin, tannin, organic acid. The results of priliminary test provide evidence for further study of the chemical compositions and biological activities of Hedyotis uncinella HooK. et Am.
