The objective of the present work is to carry out the physicochemical investigation of powder drug and phytochemical screening of different fractions obtained from hydroalcoholic extract of Tectona grandis (Linn) barks. Physicochemical analysis was done to determining total ash, acid insoluble ash, water soluble ash, sulphated ash, extractive value, moisture content, crude fibre content and foaming index. The inorganic elements determination and fluorescence analysis was performed as per the standard methods. Phytochemical investigations were carried out on different fraction to determine various active constituents present in it by using standard preliminary phytochemical tests. The inorganic element, such as calcium, magnesium, sodium, potassium, iron, copper, zinc and manganese were found in the hydroalcoholic extract of barks. Florescence analysis of the fractions were reported which gives the sensitivity of the chemical in different chemical reagents. Preliminary phytochemical screening of different fractions of hydroalcoholic extract showed the presence of the phytoconstituents like alkaloids, glycoside, proteins and amino acid, carbohydrates, flavonoids, terpenoids, tannins, saponins and sterols. However the volatile oil, fixed oil and mucilage were found to be absent. The physiochemical examination of the barks of Tectona grandis Linn (Saguan) can be used as rapid, inexpensive botanical identification and standardization. The phytochemical data obtained from the results of the Tectona grandis fractions may be useful for further pharmacological evaluation.
