Qualitative and quantitative analysis of phytochemicals in crude extract of big – Leaf mahogany (Swietenia macrophylla King.)

Abstract

The present study investigates the qualitative and quantitative analysis of major bioactive constituents of medicinally important tree, Swietenia macrophylla in its methanol extract of leaf, seed and central-fruit-axis. The qualitative phytochemical tests exhibited the presences of common phyto-compounds including alkaloids, flavonoids, tannins, terpenoids, glycosides, saponins, and volatile oils as major active constituents. Alkaloids, terpenoids and carbohydrates are major compounds in both leaf extract and seed extract. Flavonoids and fixed oil are absent in leaf extract. Tannins and glycosides are not found in the seed extract. Tannin is major chemical compound in leaf and central-fruit-axis. Steroids and amino acids are found in all the extracts. The high content of tannins, alkaloids and flavonoids was found in seed extract where as high phenols was recorded in leaf extract.
