Phytochemical Screening and Evaluation of Antioxidant, Antidiabetic, and Antimicrobial Potential of Bergenia ligulata

Bergenia ligulata, locally known as “Pashanbheda,” belongs to the family Saxifragaceae and is a perennial herb with a short and thick stem. This plant has numerous medicinal properties including antioxidant, antidiabetic, antibacterial, and anti-inflammatory properties. The qualitative and quantitative analysis shows that the rhizome of this plant contains various phytochemical constituents. Qualitative analysis shows that it contains phenols, flavonoids, tannins, terpenoids, alkaloids, steroids, carbohydrates, and glycosides. Thirty- two bioactive compounds were identifiedduring GC-MS analysis. Dihydro-3-methylene-5-methyl-2-furanon, Stigmast-5-en-3-ol, 9-Octadecenamide(Z), 6,9-Octadecadienoic acid, methyl ester, 9,12-Octadecadienoic acid (Z, Z)-, methyl compounds have antioxidant, antibacterial and anti-inflammatory activities. The total phenol and flavonoid content from the quantitative analysis revealed a significant amount of phenol i.e., 67.1±0.02*6mg/g, and flavonoid content i.e., 89.11±0.01* mg/g. In vitro, antioxidant activities were estimated by diphenyl-1-picrylhydrazyl assay showing the highest % inhibition of 47.24±0.06* for plant extract and 41.63±0.057* for standard respectively. The in vitro, antidiabetic activitieswere estimated by alpha-amylase inhibition assay showing the highest % inhibition of 67.14±0.05* at 250 μg/ ml for methanolic plant extract and 61.42±0.01* at 250 μg/ ml for standard and in vitro antibacterial potential were detected by using Agar well diffusion process. The anti-bacterial action was found maximum in aqueous plant extract against staphylococcus aureus bacteria.
