Abstract

The present investigation was carried out for the qualitative screening of major phytochemical groups and to identify specific bioactive compounds present in the methanolic leaf extracts of Polyalthia korinti (Dunal) Benth. & J. Hk. ex J. Hk. & Thoms. The qualitative screening of phytochemical groups was done using the standard procedures described in Experimental Phytopharmacognosy and the identification of bioactive compounds by using GC-MS analysis. The qualitative phytochemical screening revealed the presence of phenolics, flavonoids, alkaloids, tannins, glycosides, terpenoids and carbohydrates. The GC-MS analysis identified 33 phytocompounds of which most of them were reported to have important biological activities. The study confirmed the medicinal property of P. korinti and suggest that further research works are to be carried out for the utilization of the active principles for future drug developments.

Keywords: Polyalthia korinti, qualitative phytochemical screening, GC-MS analysis, bioactivity of compound.
