Gmelina asiatica Linn, (syn. Gmelina parvifolia) (Family, Verbenaceae) is commonly known as ‘Asian Bush beech’ and large straggling shrub found in South India. The plant has been used in gonorrhea, catarrh of the bladder, rheumatism. A study on Gmelina asiatica stem samples extracted the air-dried stem powder with different solvents such as Hexane, Chloroform, alcoholic and sterile water. Preliminary phytochemical analysis was done long with measurement of the leaf constants, fluorescence characteristics and extractive values. Quantitative estimation of total ash value, acid insoluble ash and water soluble ash may useful for identification of the powdered drug. The studies suggest that the observed pharmacognostic and physiochemical parameters are of great value in quality control and formulation development of Gmelina asiatica.
Key words: Gmelina asiatica stem, fluorescence analysis, macroscopy, microscopy, pharmacognostic standardization, phytochemical screening.
