Tropical dry deciduous forests are famous for their many uses. They are rich storehouses of medicinal plants used as raw material in industry or manufacture of drugs. Medicinal plants are valuable sources of new drugs globally. Medicinal plants are an important part of nature's resources, and they are now accepted worldwide. Buchanania lanzan plant, apart from its natural therapeutic value against various diseases, also provides high quality food for livelihood. It is a wild tropical deciduous forest plant that has been used as food around the world. The aim of the present work was to analyze the constituents of various phytochemicals on ethyl acetate, dichloromethane and methanol extracts of B. lanzan leaf. The leaves of this plant were collected from Ratapani forest area of Sehore district (Madhya Pradesh), India. Qualitative phytochemical analysis by TLC and HPTLC was attempted in this study. The present study suggested that TLC studies constituted different colored phytochemicals with various Rf values and the leaf contains classes of compounds tested namely alkaloids, flavonoids, phenols and tannins. And by the HPTLC analysis ethyl acetate extract of leaf shows the diversity of phenolic group at the 254 nm and 366 nm wavelengths using Toluene: ethyl acetate (7:3 v/v) mobile phase. These findings suggested that selected extracts of B. lanzan leaves could be a potential source of drugs that could be important for the production of synthetically improved therapeutic agents in the future. Medicinal plants can be a substantial source of revenue for rural people in developing nations, mainly through selling wild-harvested material.
