POLLEN MORPHOLOGY, PHYTOCHEMICAL TEST AND ANTIMICROBIAL ACTIVITIES OF TEA LEAVES FOUND IN WAN SAING VILLAGE, KYAING TONG
Abstract
- From the methanolic extract of green tea leaves of Camellia sinensis (L) Kuntze, collected from Wan - Saing, a Loi (ethics minority in Myanmar) village within the Tract of Kat- Pha, Kyaing Tong District, Eastern of Shan State. Phytochemical contents of the tea leaves were analyzed and evaluated. By these analyses, carbohydrate, glycoside, phenolic compound, - amino acid, saponin, tannin, flavonoid, steroid, terpenoid and reducing sugar are found to be present. Notably, starch and cyanogenic glycosides were not observed in the extract sample under study. In addition the values of the nutrients from the leaf extract were examined using AOAC (Analytical Official of Chemic Method). As a result the energy value was found to be the highest with the potential value of 280 % whereas carbohydrate content is second in line with the concentration of 51.33%. The concentric percent of the remaining nutrients such as moisture, ash, crude protein, crude fiber and crude fat were found to be 11.73%, 5.02%, 10.42%, 17.80% and 3.70% respectively. Caffeine concentration was found as the lowest in concentration (0.27%). By agar-well diffusion method, using different kinds of solvents, the antimicrobial activity of constituents from the leaf extract were studied. Their inhibitory zones were also evaluated.
