Abstract

• The plant Artocarpus lamellosus Blanco is an unrecorded species in Myanmar, belong to the family Moreaceae. It was collected from University of Yangon Campus, Kamayut Township. The aim of the present study on qualitative and quantitative phytochemical screening of the Artocarpus lamellosus Blanco and its microbial activity. In preliminary phytochemical analysis, the three different extracts such as HCL, ethanol and water extracts of leaves were found alkaloids, flavonoids, glycosides, phenolic compounds, saponins, starch, reducing sugars, carbohydrates, proteins, tannins and α-amino acid. In quantitative analysis, moisture content, acid-insoluble ash, water soluble ash. The extractive values with different solvents and ash values were also analyzed and recorded. The elemental analysis and the presence of the toxic elements of the leaves were analyzed by using Atomic Absorption Spectrophotometer (AAS). According to the result, it was revealed that moisture content (7.62%), total ash (6.24%), acid insoluble ash (75. 06%) and water soluble ash (9.73%). According to the extractive value result, the phytoconstituents of Artocarpus lamellosus Blanco were the highest soluble in petroleum ether whereas the least soluble in water or methanol. The nutritional value of the leaves was analyzed. Antimicrobial activities of Artocarpus lamellosus Blanco were investigated with seven extracts of different solvents from the powdered leaves on eight test organisms by agar well diffusion assay. Among them, antimicrobial activity on pathogenic microorganism, Salmonella typhi and the weakly antifungal activity was found on Escherichia coli.
