Abstract

• Operculina turpethum (L.) Silva. (Kyar-hin) belongs to the family Convolvulaceae. In this research work, the specimens were collected from Dagon University Campus, East Dagon Township, Yangon Region, during the flowering and fruiting periods from February to July, 2023. In this paper, the morphological characters of plant and microscopical characters of leaves were studied at the Department of Botany, Dagon University by using available literatures. In morphological study, the plant was veins, stem with 3-5 wings; leaves were ovate, pubescent; flower white; sepal persistent, carpel-2, axile placentation. The microscopical characters of leaves were conducted by free hand section method. In microscopical study paracytic type of stomata was found in both surface and non-glandular trichomes were present. The preliminary phytochemical test of powdered leaves was examined in Dagon University. Alkaloid, carbohydrate, glycoside, phenolic compound, reducing sugar, flavonoid, saponin and tannin were present. The nutritional value was examined by David Pearson and Kjeldaha method and antioxidant activitiy was also examined by DPPH Assay Method at the Small Scale Industry Departments in North Okkalapa Township. This powder was found to contain carbohydrates, fiber, fat, proteins, ash and moisture, and energy value 320.73 kcal. Elemental analysis of the powder was found the elements, such as Ca, K, Fe, Cu and Sr. The antimicrobial activities of three extracts of sample showed against on Agrobacterium spp., among them Butanol extract is most affected to the test organisms.
