Preliminary Study on Quality Analysis of Yao Medicine Pileostegia tomentella Hand. -Mazz.

[Objectives] To establish a method for quality analysis of Medicine Pileostegia tomentella Hand. -Mazz. [Methods] According to the testing method of Chinese Pharmacopoeia (2020 Edition), the water content, total ash and alcohol-soluble extract of P. tomentella Hand. -Mazz. were determined. [Results] 10 batches of P. tomentella Hand. -Mazz. from different habitats and in different collection time in Guan- gxi all had the same plant morphology and medicinal properties. The experimental results showed that the water content was 7.92%-10.35%, the total ash content was 5.53% -6.62%, the acid-insoluble ash content was 0.59%-0.76%, and the extract content was 11.63%-16.12%. [Conclusions] The identification method in this study can be used for the quality analysis of P. tomentella Hand. -Mazz., and the experimen- tal results can provide a scientific basis for the development and utilization of P. tomentella Hand. -Mazz. and the establishment of its quality standard.
