Abstract:
Objective To identify the content of tubeimoside I in Paniculate Bolbostemma from 16 differ-ent locations and determine the high-containing locations and influencing factors.Methods The quanti-tative determination method of tobeimoside I in Tubeimu(Paniculate Bolbostemma, Rhizoma Bolbostem-atis)in Chinese Pharmacopoeia(2015 Edition)was used to determine the content of tobeimoside I in 16 batches of Tubeimu for deciding producing areas with higher content of Tubeimu and analyzing the influ-encing factors.The origin producing areas was classified by using group-average clustering analysis meth-od taken content of tobeimoside I as the index.Results The results showed that the content of tobeimo-side I was in a range from 1.234%to 3.174%in different producing areas,which was accorded with the requirement of Chinese Pharmacopoeia.The clustering analysis classified 16 producing areas into 4 groups,and content of tobeimoside I was the highest in Tubeimu material produced from Shangluo and Hanzhong.Conclusion The temperature and humidity had influence on Tubeimu material, and content of tobeimoside I was higher in the producing areas with higher temperature and humidity.
