Antioxidant and Antidiabetic activity of hydroalcoholic flower extract of Woodfordia fruticosa (L.) Kurz

Abstract

Woodfordia fruticosa (L.) Kurz, (W. fruticosa) a member of the Lythraceae family, commonly known as dhaiphul, has been used in traditional medicine to cure common illnesses since ancient times. The most effective part of this plant is the flower which has a high demand in the national as well as the international market of the eastern south part of Asian countries. The present study focuses on exploring the presence of phytochemicals, antioxidants, and antidiabetic potential of hydroalcoholic extract of flower of W. fruticosa. Phytochemical test showed the presence of saponin, flavonoid, carbohydrates, alkaloids, tannin, anthraquinone, and triterpenoids in the extract, and it showed an effective result of total phenolic content, total flavonoid Content with the value of 371.96 ± 2.86 mg of gallic acid equivalent per gram of the extract and 113.82 ± 0.178 mg of quercetin equivalent per gram of dry weight. In vitro antioxidant assay, for the DPPH assay, the IC50 values were found 30.85 ± 0.36 μg/ml and 22.35 ± 0.54 μg/ml for the extract of W. fruticosa flower and ascorbic acid respectively and for the FRAP Assay, the reducing power assay of plant extract is lesser than standard (Ascorbic acid). W. fruticosa also showed significant hyperglycemic activity. In accordance with results, we can conclude that plant consists of a high polyphenolic and flavonoid group which help in antioxidant activity as well as the hydroalcoholic extract shows mild activity against diabetes.
