Abstract

Natural products are promising source of drugs in pharmaceutical industry, used for the treatment of diseases and serves as a lead molecule for the synthesis of potent drugs. Therefore, current research work was planned to investigate in-vitro antioxidant, antidiabetic and hypolipidemic potential.  For this purpose, different parts of Albizia lebbeck, Mangifera indica, Vitis vinifera L., Syzygium jambolanum. jambolanum, Abelmoschus esculentus, Calotropis procera, Grewia asiatica, Morus alba, and Leucaena leucocephala were collected from South Punjab. After collection, these parts were dried and extraction was performed by maceration. Total phenolics and total flavonoids contents were measured. Antioxidant potential, in-vitro α-glucosidase, α- amylase, lipase, lipoxygenase and urease inhibition assay was performed.  Result showed that C. procera (leaves) had maximum phenolic content of 66 mg/g equivalent of gallic acid and had maximum flavonoid content of 76mg/g equivalent of quercetin. Ficus carica (leaves) showed maximum antioxidant potential of 86%. V. vinifera (leaves) showed inhibitory concentration of 50 for lipoxygenase assay. Ab. esculentus (aerial) showed maximum percentage inhibition of 87% for α-glucosidase inhibition assay. V. vinifera (leaves) showed maximum inhibition of 79% for α- amylase inhibition assay. C. procera (leaves) had maximum percentage inhibition of 83% for lipase assay. Ab. esculentus (aerial part) showed inhibitory concentration of 37 for urease assay. It is concluded from the aforementioned results that C. procera leaves showed strong DPPH inhibition, lipase inhibition and urease inhibition potential. V. vinifera leaves had significant lipoxygenase inhibition, lipid modulating and antidiabetic potential whereas C. procera leaves possessed promising lipid-modulating properties. Therefore, these plants may be helpful in the development of novel therapeutic approaches for dyslipidemia and related metabolic disorders.
