在模拟人工胃肠道环境中博落回主要生物碱类成分的稳定性特征分析
Stability Analysis of Major Alkaloids in Macleaya cordata under Simulated Gastrointestinal Environment
摘要
Abstract
Objective:In order to explain the reasons of low bioavailability of four alkaloids (protopine,allocrypto pine,sanguinarine,chelerythrine) in Macleaya cordata,the study explored the stability of four alkaloids in the simulated gastrointestinal environment.Methods:A high performance liquid chromatography method was used to determine the stability of four alkaloids in M.cordata under the environment of different pH media,artificial gastric juice (pH =1.3) and artificial intestinal juice (pH =6.8).Results:The recovery rate of protopine and allocryptopine were ranging from 97.16% to 101.89% in the environment of acidic,neutral,alkalinity media,artificial gastric juice and artificial intestinal juice for 8 h.The recovery rate of sanguinarine was 48.81%-60.53 % in the environment of pH =6.8 phosphate buffer solution (PBS),water,pH =7.8-8.0 PBS and artificial intestinal juice for 8 h.The recovery rate of chelerythrine was 81.21%-93.48% in the environment of pH =5.8 PBS,pH =6.8 PBS,water and artificial intestinal juice for 8 h,while in the environment of pH =7.8-8.0 PBS for 8 h,the recovery rate of chelerythrine was 57.43%.Conclusion:The stability of protopine and allocryptopine was not affected by pH.While along with the increase of pH,the stability of sanguinarine and chelerythrine was reduced.The stability of four alkaloids in M.cordata under the simulated gastrointestinal environment accorded with the environment of different pH media.The results provide a scientific basis for clarifying the pharmacokinetic characteristics of Sangrovit.关键词
