摘　　要：此研究分析了四川内江两种野生天冬的形态特征和活性成分含量,结果发现:大天冬的块长8~14 cm,直径2.2~3 cm,平均质量在60 g左右;总多糖、总皂苷、游离氨基酸含量分别为16.17,3.63和1.98 g/100 g,优于目前其他种植产地的天冬。这表明,野生大天冬可作为日后大规模人工栽培的优质品种。此研究还分析了去皮对大天冬活性成分含量的影响,结果发现去皮导致大天冬总多糖含量下降近22%,总皂苷降低约32.5%,游离氨基酸总量下降约15.6%。这表明,天冬药材在加工过程中可以考虑不再进行去皮处理,一方面能节省药材资源,另一方面也能为日后药材加工方式的改善提供理论依据。In this research,the morphological characteristics and active components content of two wild Asparagus cochinchinensis in Neijiang,Sichuan Province were compared.We found that the length was about 8-14 cm,the diameter was 2.2-3 cm,and the average weight was about 60 g of the large Asparagus cochinchinensis.The contents of total polysaccharides,total saponins and free amino acids were 16.17 g/100 g,3.63 g/100 g and 1.98 g/100 g,respectively,which were superior to those in other planting areas.This result indicated that the large Asparagus cochinchinensis could be used as a high-quality variety for large-scale artificial cultivation in the future.In addition,the impact of peeling on the amount of active ingredients in the large Asparagus cochinchinensis was examined.It was discovered that after peeling,the contents of total polysaccharides,total saponins,and total free amino acids decreased by nearly 22%,about 32.5%,and 15.6%,respectively.This result suggested that it could be considered not to peel the medicinal materials of Asparagus cochinchinensis in the processing process.On the one hand,it could save medicinal materials resources,and on the other hand,it could provide a theoretical basis for improving the processing method of medicinal materials in the future.
