Qualitative and quantitative phytochemical studies of helianthus tuberosus L.

Abstract

Helianthus tuberosus L. is a biotechnologically and medicinally important plant. Five accessions of H. tuberosus were analyzed for phytoconstituents to identify the accession with the highest content of medicinal compounds. The aqueous and ethanolic extracts of leaves and shoots were qualitatively tested for secondary metabolites. The total phenolic contents were estimated in leaves and tubers of five accessions of H. tuberosus to select the accessions with highest total phenolic content. In the present study qualitative analysis confirmed that the presence of various phytoconstituents like saponins, alkaloids, phenolics, tannins, steroids, glycosides. In leaves, the total phenolic content ranged from 87.83 ± 1.05 to 127.23±1.34mg GAE/g. In tubers, the total phenolic content ranged from 7.06±0.27 to 20.43±0.69mg GAE/g. The accessions TUB-1715 identified showed highest total phenolic content in both leaves and tubers. The plant extracts have many applications like antioxidant, anticancer and antifungal activities.
