剑叶龙血树根、茎、叶中血竭成分分析

Analysis of loureirins in roots,stems,and leaves of Dracaena cochinchinensis

目的通过对比剑叶龙血树根、茎、叶成分与龙血竭成分间的异同及对剑叶龙血树根、茎、叶中龙血素A、B的测定,寻找龙血竭原料的可能来源。方法薄层色谱法及高效液相色谱技术。结果剑叶龙血树根、茎、叶中均含有微量的龙血素A,分别为:58、53、15μg/g;叶中还含有微量的龙血素B,为2μg/g,而根、茎样品中未能检测到龙血素B。结论从色谱峰的积分面积及保留时间来看,剑叶龙血树根、茎、叶成分与血竭原料有少许的相关性,但差异显著;根、茎、叶3者间的化学组成成分也存在着显著差异,剑叶龙血树根、茎、叶中龙血素量都较低,不能直接用作生产血竭的原料。

Objective The experiment compared the chemical components in the roots, stems, and leaves of Dracaena cockinchinensis with those in the raw material of Dragon＇s blood, in order to find the possible raw material of Dragon＇s blood. Methods Technology of thin layer chromatography （TLC） and high performance liquid chromatography （HPLC）. Results The results showed that the roots, stems, and leaves of D. cochinchinensis just contained small amount of loureirin A, the contents of loureirin A of the three samples are： 58, 53, and 15μg/g, respectively. Loureirin B was only detected in the leaves with content of 2μg/g. Conclusion From the analysis of peak areas and the retention time, there are only slight correlations among the components of the four samples and the chemical components among the roots, stem, and leaves are different. Moreover, there is too low content of loureirins in the roots, stem, and leaves to be raw material of Dragon＇s blood.
