樗鸡化学成分的初步研究

Chemical constituents of the Lycorma delicatula

目的：对传统中药樗鸡（ＬｙｃｏｒｍａｄｅｌｉｃａｔｕｌａＷｈｉｔｅ）的化学成分进行研究，确定其化学组成。方法：采用梯度溶媒提取分离，结合试管法及薄层法进行鉴定。氨基酸分析和微量元素分析分别利用全自动氨基酸分析仪及高频等离子体光量计自动分析仪。结果：将樗鸡的无水乙醇提取液分成酸性、碱性、中性三部分后，酸性部分的乙醚提取液部分含有酚类和有机酸类成分，碱性部分的氯仿提取液部分含有生物碱；水提液中含有游离氨基酸、多肽、蛋白质、糖类和有机酸；微量元素钙、铁、镁、磷、锌在樗鸡体内含量异常丰富。结论：碱性部分的氯仿提取液中的生物碱可能是其特异性化学成分，结合丰富的微量元素结果。

OBJECTIVE:To identify the chemical constituents of Lycorma delicatula by the means of chemical pre experiments.METHOD:To isolate and identify the chemical constituents,the solvent extraction together with the methods of tube and TLC,auto amino acid analytical instrument and the micro analytical instrument were used.RESULTS:In the part of ethanol extracts of Lycorma delicatula,constituents of phenol and organic acid were found.In the part of ether extracts,alkaloids were found.In the part of water extracts,free amino acids,polypeptide,protein,carbohydrate and organic acid were found,and it proved that the amount of free amino acid was very high,and the amount of trace elements such as calcium,iron,magnesium,phosphorus and zinc were high.CONCLUSION:Alkaloids are the most special constituents of Lycorma delicatula White.
