Abstract

The morphological characteristics of Tinospora cordifolia and Tinospora crispa were observed and described. The stem powder of both species was analyzed for moisture content, total ash, foreign matter ratio, preliminary phytochemical analysis activity, qualitative and quantitative determination of total alkaloids by thin layer chromatography (TLC) and UV-Visible spectrophotometry method. The α-glucosidase inhibitory effect was evaluated. Research recorded morphological characteristics, moisture content, total ash, and foreign matter ratio of Tinospora cordifolia and Tinospora crispa. Quantitative analysis by spectrophotometry showed significant differences in total alkaloids between the two species. Moreover, the α-glucosidase enzyme inhibition activity of both species was potentially stronger than the positive control Acarbose, in Tinospora crispa has the strongest activity.
