Qualitative and Quantitative Determination of Secondary Metabolites of Lagerstroemia Parviflora Roxb Leaves

Herbal medicines as the major remedy in traditional system of medicine have been used in medical practices since antiquity. In addition to its ancient historical uses, Lagerstroemia parviflora Roxb (L. parviflora) is used in several systems of medicine for a variety of ailments. The bioactive compounds that are produced by plants are collectively called as Phytochemicals. The phytochemical ingredients are plant derived compounds which protect the plants from environmental stresses, including insects, bacteria and fungus and weather changes. Though phytochemicals are not considered essential nutrients, it has become apparent that they offer many health benefits to the plants. The aim of the present study is to examine L. parviflora leaves for phytochemical profile. Qualitative analysis of various phytochemical constituents and quantitative analysis of total flavonoids were determined by the well-known test protocol available in the literature. TLC analysis of the methanolic fraction of the leaves was carried out using the solvent system Toluene: Ethyl acetate: Formic acid (in 5:4:1 ratio). Phytochemical analysis revealed the presence of phenols, flavonoids, tannins, saponins, alkaloids, fixed oil and fats. It is expected that the important phytochemical properties recognized by our study in the indigenous medicinal plants will be very useful in the curing of various diseases when taken along with our food.
