PHYTOCHEMICAL INVESTIGATION INTO LEAVES OF ELSHOLTZIA BLANDA (BENTH.) BENTH. AND ITS ANTIMICROBIAL ACTIVITY
Abstract
- Elsholtzia blanda (Benth.) Benth.is an aromatic an annual herb, locally known as Ar-pu-ywat which belongs to family Lamiaceae. It’s distribution extend to Bangladesh, India, Malaysia, China and Myanmar especially in Rakhaine state. This plant is commonly used as traditional herbal medicine as well as vegetable and spices. After the sample collection in Yepawgyi village, Taunggoke Township, the genus and species were checked by studying the morphological characters with available literatures. The present work was conducted during February 2017 to July 2018 and mainly deals with photochemical analyses, antimicrobial activity of leaf-extracts and elemental analyses of dried powdered leaves. The results of phytochemical analyses indicated the presence of glycosides, reducing sugar, steroid, carbohydrates, phenolic compound, terpenoid, flavonoid, netural compound, alkaloid, saponin, α-amino acid and tannin in the leaves. The cyanogenetic glycoside was not detected. The elemental analysis on the dried leaves of Elsholtzia blanda (Benth) Benth revealed that a part from hydrocarbon (91.45%), the most abundant elements were K (4.5%), Ca (2.3) and Si (0.97%). The antimicrobial activity of leaves extracted by acetone, butanol, ethanol, ethyl acetate, methanol, pet-ether and water was studied. The acetone, butanol, ethanol, ethyl acetate and methanol showed distinct inhibitory effects on Bacillus sublilis, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus pumilus, Candida albican, Escherichia coli and Agrobacterium spp. The ethyl acetate extract possessed the highest antimicrobial activity on seven test organisms. The pet ether and water extracts did not inhibit the test organisms.
