| 摘要 | [Objectives] This study was conducted to determine and compare the contents of flavonoids in the leaves of Tetracera asiatica, an ethnic medicine from different habitats, in order to provide a basis for the quality control of its medicinal materials. [Methods] The flavonoid compounds in the leaves of T. asiatica were reflux-extracted in a water bath, and the total flavonoid content in T. asiatica was determined by ultraviolet-visible spectrophotometry. [Results] The total flavonoid content in T. asiatica leaves varied according to different habitats. The highest content was found in Gaofeng (19.41%) of Guangxi, followed by Huizhou (16.88%) of Guangdong and Hong Kong (16.76%). The lowest total flavonoid content was found in Shangcuntang (3.91%) of Bobai County, Guangxi, followed by Beiliu (4.15%), Guangxi. The total flavonoid contents in the samples ranged from 3.91% to 19.41%, with an average content of about 12.36%. [Conclusions] The UV spectrophotometry method is easy to operate, and has good repeatability, accurate detection results, and high reliability, and can be used for the determination of flavonoids in T. asiatica. |
