不同产区天冬主要有效成分含量比较

Comparison of Alcohol-soluble Leachings and Polysaccharides of Asparagus Cochinchinensis(Lour.)Merr.in Different Production Areas

目的探讨不同产区天冬中主要有效成分多糖、醇溶性浸出物的含量差异,为进一步完善天冬质量评价体系提供参考。方法按《中华人民共和国药典》方法测定四川、重庆、广西、贵州、云南产区天冬浸出物含量;用苯酚-硫酸比色法测定四川、重庆、广西、贵州、云南产区天冬多糖含量。比较不同产区含量的差异。结果天冬浸出物含量由高到低为贵州、四川、云南、重庆、广西,分别为90.12%、89.68%、88.54%、88.24%、87.63%,野生天冬浸出物含量比栽培低。天冬多糖含量由高到低为云南、四川、贵州、重庆、广西,分别为33.66%、25.88%、23.54%、23.05%、22.14%。结论由于生长环境和种内差异,不同产区天冬主要有效成分多糖、醇溶性浸出物含量差异明显。

Objective To explore the differences of alcohol-soluble leachings and polysaccharides of Asparagus cochinchinensis(Lour.)Merr.in different production areas to provide reference for further improving the quality evaluation system of Asparagus cochinchinensis(Lour.)Merr.Methods The alcohol-soluble leachings of Asparagus cochinchinensis(Lour.)Merr.in Sichuan,Chongqing,Guangxi,Guizhou and Yunnan were tested according to the Chinese Pharmacopoeia,the polysaccharides of Asparagus cochinchinensis(Lour.)Merr.in Sichuan,Chongqing,Guangxi,Guizhou and Yunnan were tested by phenol-sulfuric acid colorimetry.The differences in main active ingredient of different production areas were compared.Results The alcohol-soluble leachings of Asparagus cochinchinensis(Lour.)Merr.from high to low was Guizhou,Sichuan,Yunnan,Chongqing,and Guangxi,contents are as follows 90.12%,89.68%,88.54%,88.24%,87.63%,the content of wild Asparagus cochinchinensis(Lour.)Merr.was lower than that of cultivated.The polysaccharide of Asparagus cochinchinensis(Lour.)Merr.from high to low was Yunnan,Sichuan,Guizhou,Chongqing and Guangxi,contents are as follows 33.66%,25.88%,23.54%,23.05%,22.14%.Conclusion Due to the differences in growth environment and intracecies,the contents of alcohol-soluble leaching and polysaccharide of Asparagus cochinchinensis(Lour.)Merr.was Significantly different in different production areas.
