Pharmacognostic Identification of Yi Medicine Herba Boenninghauseniae Albiflorae

[Objectives] To identify original plant and traits of Yi medicine Herba Boenninghauseniae Albiflorae,and provide experimental data for its identification and application. [Methods] The original plant,traits,and microscopic identification were used. [Results] Essential identification characteristics of Yi medicine Herba Boenninghauseniae Albiflorae: small leaf was 1-2. 5 cm long,while the gynophore was 4-8mm long when bearing fruit; traits mainly included characteristic odor,strong and bitter taste,and spicy flavor; microscopic exclusive identifying characteristics: rich aleurone grain in the root; leaf had lysigenous secretory cavity,and non-glandular hairs and oil droplets were common. [Conclusions] Yi medicine Herba Boenninghauseniae Albiflorae( Ebazema) has distinctive identifying characteristics in original plant,traits,and microscopic tissues. This study is expected to provide certain reference for identification of original plant and medicine and formulation of quality standard for Yi medicine Ebazema,and to provide basis for its further research and development.

Quality Evaluation of Yi Medicine "Qibujing" Based on Determination of Water Content and Ash Content

[Objectives]To determine the water content,total ash content and acid-insoluble ash content of Yi medicinal material"Qibujing",so as to provide experimental basis for establishing the Quality Standard(Draft)of Yi Medicinal Material"Qibujing"in Sichuan Province.[Methods]According to the second method(drying method)in 0832 water content determination method and 2301 ash content determination method in Chinese Pharmacopoeia(2015 Edition),it was determined,respectively,and the data were processed by IBM SPSS Statistics 26 and DPS 7.05 data processing system.[Results]All the 14 batches of sample met the stipulation that the water content should not exceed 12.0%,the total ash content should not exceed 8.0%,and the acid-insoluble ash content should not exceed 1.5%under"Guan Zhong-(Qibujing)"in the 2005 edition of Yunnan Traditional Chinese Medicine Standard.There was a negative correlation between water content,acid-insoluble ash content and altitude,and a positive correlation between total ash content and altitude.[Conclusions]It is suggested that Quality Standard(Draft)of Yi Medicinal Material"Qibujing"in Sichuan Province stipulate that the water content should not exceed 12.0%,the total ash content should not exceed 8.0%,and the acid-insoluble ash content should not exceed 1.5%.
