Abstract: 

The study investigates the phytochemical profile of Terminalia arjuna bark (Commercially available powder) extracts prepared using two extraction methodssuch as Soxhlet extraction and cold macerationwith solvents of varying polarity (ethanol, methanol, ethyl acetate, hexane, and aqueous). Preliminary phytochemical screening was conducted to detect bioactive compounds. The results demonstrated that Soxhlet extraction enabled a wider recovery of phyto-constituents compared to cold maceration. Ethanol and methanol extracts were especially rich in phenols, tannins, steroids, alkaloids, while aqueous extracts consistently showed phenols, tannins, steroids, alkaloids, and saponins. Hexane extracts predominantly alkaloids. Cold maceration, although effective in extracting some alkaloid, tannin, saponin and phenol compounds, was less efficient overall, yielding a narrower phytochemical spectrum. These results confirm that Terminalia Arjuna bark is a potent source of diverse phytoconstituents with potential pharmacological importance, and that Soxhlet extraction may be regarded as a superior technique for the effective recovery of bioactive compounds.
