Abstract
Air dried powdered material of the fruits of cedrela toona Roxb. was successively extracted with petroleum ether, hexane, acetone, methanol and water extract by soxhlet extraction and subjected to various qualitative chemical tests to determine presence of various phytoconstituents like alkaloids, glycosides, carbohydrates, phenolics and tannins, phtosterols, fixed oils and fats, proteins, amino acids, flavonoids, saponins etc. Total flavonoids content was measured with the ‘Aluminium Chloride Colorimetric Assay Method’. Total Phenolic content in the aqueous and methanol extracts of fruits of Cedrela toona Roxb. were determined using the Folin Denis Method and expressed as mg of tannic acid equivalents per gram dry weight of extract. This study helps researchers for developmentof isolation method of active ingredient having vast pharmacological effects.
 Keywords: Cedrela toona, total flavonoids, total tannins and phenolics, Tannic acid
Highlights
Literature survey reveals that Cedrela toona Roxb. is medium sized to large deciduous tree with brown to grey scaly bark
Flavonoid content was higher in alcoholic extract of Cedrela toona Roxb. fruits extract than water extract
Total phenolic content calculated in terms of tannic acid in the aqueous and methanol extracts of fruits of Cedrela toona Roxb.were found to be 9.44 %w/w and 18.44 % w/w respectively
