浙贝母花、地上茎与鳞茎总生物碱、总皂苷含量测定的比较

Content Measurement of Bulb Total Alkaloid and Saponin in Zhejiang Fritillariae and Thuubergii

[目的]通过测定和比较浙贝母花、茎、鳞茎在生物碱和皂苷的含量上的区别,探讨建立合理的浙贝母药材各部位的合理利用。[方法]用两相滴定法测定浙贝母三个部位的生物碱含量;用重量法测定浙贝母三个部位的皂苷含量。[结论]浙贝母生物碱含量花为0.182%,茎为0.047%,鳞茎为0.341%。皂苷花为5.112%,茎为8.840%,鳞茎为1.724%。[结果]其主要成分的差异为合理利用浙贝母的花及地上茎提供了依据。

[Objective] To mensurate and compare with the mensuration of alkaloid and saponin in the flower, pedicel and bulb of fritillariae thuubergii,make full use of all parts of fritillariae thuubergii. [Method]To mensurate the mensuration of alkaloid and saponin in the three parts of fritillariae with the twophase titration method and gravimetric method. [Result]The mensuration of alkaloid in the flowers of fritillariae thuubergii is 0. 182 %, while it is 0. 047 % and 0. 341% in the pedicel and bulb separately, and the mensuration of saponin in the flowers of fritillarae thuubergii is 5. 112% ,while it is 8. 840% and 1. 724% in the pedicel and bulb separately. [Conclution] The difference of major component in the fritillariae thuubergii offers the foundation to make full use of the flowers, pedicel and bulb.
