[Effect of origin species, body weight, and gender on quality of Bufonis Venenum].

Based on standard sampling for Bufonis Venenum, this study analyzed the effect of the origin, and body weight and gender of Bufo bufo gargarizans on the quality of Bufonis Venenum. To be specific, mass spectrometry(MS) and the content determination methods in Chinese Pharmacopoeia(2020) were adopted. First, MS was performed on 76 Bufonis Venenum samples collected from 40 cities/counties in 17 provinces/autonomous regions which were derived from B.

[Distribution characteristics of Bufo bufo gargarizans resources in China based on quality evaluation of Bufonis Venenum].

On the premise of strictly controlling the harvesting conditions of Bufonis Venenum, we studied the relationship between the quality and resource distribution of Bufonis Venenum in China, aiming to provide the data for comprehensively understanding the geographical distribution and characteristics of Bufonis Venenum in China. In this study, 105 samples of Bufonis Venenum were collected from 42 counties and cities in 19 provinces in China, and the material basis and index components were determined by mass spectrometry and high performance liquid chromatography. The obtained data formed the quality database of Bufonis Venenum from different producing areas in China.
