目的考察产地和生长年限对土茯苓中落新妇苷含量的影响,了解近年来土茯苓商品的来源和各地产土茯苓落新妇苷含量的分布情况。方法实地调查、采集并采用HPLC测定落新妇苷的含量。结果目前市场上土茯苓商品主要来自国内南方各省,此外还有部分来自越南。国产土茯苓有约70%的样品落新妇苷含量不符合中国药典2015版规定,而越南产土茯苓含量全部符合规定,且远高于限度要求。结论不同产地土茯苓落新妇苷含量差别较大,生长年限对土茯苓中落新妇苷含量影响较小,越南产土茯苓能否供药用尚需做进一步研究。
Objective To investigate the origin and growth period of Smilax Glabra in the content of astilbin content to understand the source of Smilax Glabra in recent years and the local soil Smilagenin content distribution. Methods Field investigation, collection and determination of astilbin by HPLC. Results At present, the products of Tuckahoe mainly come from the provinces in southern China and some from Vietnam. About 70% of the samples made from Smilax glabra do not meet the requirements of the Chinese Pharmacopoeia 2015 edition, while the content of Smilax jamesonii in Vietnam is all in accordance with the regulations and much higher than the limit requirement. Conclusion There are great differences in the content of aestrytoside in different producing areas of soil, and the growth duration has little effect on the content of astilbin in Smilax china.
