Phytochemical Analysis, Identification, Isolation, and Biological Activity of Ellagitannin from Acetone Leaf Extracts of Lagerstroemia speciosa (L.) Pers (Lythraceae)

Medicinal plants have bioactive compounds known as phytochemicals that play an important role in curing and healing of various diseases in human. Ellagitannins occur naturally in some fruits, nuts, and seeds. They form a diverse group of bioactive polyphenols with anti-Inflammatory, anticancer, antioxidant and antimicrobial activity. The medicinal plant Lagerstroemia speciosa that grows in Tamil Nadu’s Western Ghats was the subject of the current study. For assurance of quality, samples of acetone leaf extract (LALE) were used to identify the phytochemical components of the plants. The amounts of the major components are given by the GC-MS and HPLC. The present study involves the phytocompounds analysis, identification, isolation and biological activities of ellagitannin from acetone leaf extracts of L. speciosa. The phytochemical analysis shows the presents of phytocompounds in the acetone leaf extracts of experimental plant. The GC-MS analysis shows the major compounds of leaf of L. speciosa. The HPLC shows the quantitative and qualitative amount of ellagitannin in the leaf of L. speciosa. Bioassay-guided fractionation of the aqueous acetone extract of the leaves afforded three active ellagitannins, lagerstroemia, flosin B and reginin A.
