Determination of Some Phytoconstituents and Antimicrobial Activity of Flowers of Bombax Ceiba L. (Letpan) Phyu Zin Thant Su Su Kyi Nwe Oo Mon In this research paper, the flowers of Bombax ceiba L. (Letpan) were selected for chemical analysis and antimicroboal activity. The Letpan sample was collected from East Shawbyugone Village, Pyawbwe Township, Mandalay Region. From the experimental results of preliminary phytochemical tests, alkaloids, flavonoids, phenolic compounds, steroids, carbohydrates, tannins, glycosides, terpenes and saponins were present. Nutritional values such as moisture (5.07 %), ash (19.45 %), fats (0.57 %), fibers (25.95 %), proteins (8.24 %), carbohydrates (40.72 %) contents were found to be observed in flowers of Letpan respectively based on dried sample. From the EDXRF results, mineral elements such as K, Ca, Fe, Ti, Zn and Cu were found in Letpan flowers. Antimicrobial activity of various crude extracts (Pet-ether, Ethyl acetate and Ethanol) of Letpan flowers was screened against six microorganisms by Agar Well Diffusion method. Ethanol extract showed antimicrobial activity against all tested microorganisms (18 mm to 21 mm). 2025-12-01 https://meral.edu.mm/records/12760
