Abstract

• Santalum album L. is belonging to the family Santalaceae which is known as Nant-thar-phyu in Myanmar and Sandalwood in English. The samples were collected from Neibainda Hill in Pyay Township during June, 2023 and February, 2024. In this study, morphological and anatomical characters, preliminary phytochemical tests ,elemental analysis and antimicrobial activity of Santalum album L. were carried out. In morphological study, the plant is semiparasitic evergreen small tree with slender drooping branches. Leaves were simple and opposite. Flowers were complete, bisexual, regular, actinomorphic, perigynous. Perianth-segment provided with a tuft of hairs behind the stamens. Stamens 4, epipetalous, filaments long, anther dithecous, adnate, introrse. One carpel, axile placentation, one ovule, pendulous, style filiform, stigma tri-lobed, disc present, ovary half-inferior. Fruits globose drupe, seeds hard, globose or obovoid. In histological study, the epidermal cells were thin-walled parenchymatous cells and papillose formed in lower epidermis. The stomata were paracytic type and vascular bundles were collateral type and exarch. Druses-shaped calcium oxalate crystals were abundantly found in collenchyma and rarely found in parenchyma. In the preliminary phytochemical investigation, alkaloids, carbohydrates, flavonoids, glycosides, phenol, reducing sugars, saponins, starch and tannins were present and α - amino acid was absent. In the antimicrobial test, ethyl acetate extract was showed the activity on all of six microorganisms. Among them, acetone extract was showed the best activity on Staphylococcus aureus. Ethyl acetate showed activity on all organisms. Watery extract was showed activity on only Candida albicans. From the research, the findings were significance and as an authentic information could be used to future research.
