龙血竭的化学成分的鉴别

Identification on the Chemical Constituent of Dragon's Blood and Determination of its Content

目的：依照龙血竭药材的国家标准规定的方法,对龙血竭原药材进行定性鉴别。方法：本文中实验方法主要采用硅胶柱色谱法,聚酰胺柱色谱法对龙血竭中的化学成分进行分离。TLC化学成分进行定性鉴别。结果：原药材在284nm±2nm处的吸收值在0．4以上,符合龙血竭药材国家标准中,在284±2nm处吸收值不低于0．4的规定。结论：依照龙血竭的国家标准对龙血竭药材作了定性鉴别。确定本次实验中所用原药材确定为龙血竭药材,并且质量合格。

Objective： To determine the nature differentiation and its content are determined to go on for dragon＇s blood original crude drugs according to the national standard of dragoni＇s blood, Methods： in this article the experimental technique mainly uses the silica gelcolumn chromatography to isolate the chemical constituent of dragon＇s blood.TLC carries on the qualitative distinction to the chemical composition. Results： In UV experiment, the Abs of sample of dragon＇s blood is high of 0,4 at 284nm ＋ 2nm. It appropriate the national standard of dragon＇s blood. Conclusion：According to the national standard, identifical on the chemical constituent of dragon＇s blood. Make sure that medicine source is dragon＇s blood, and the quality of it is good.
