| Summary: | Passiflora foetida (Padagedi) is identified as an underutilized fruit in Sri Lanka, used in traditional medicine for several diseases. The objective of this study was to determine the antioxidant, anti-diabetic, and anti-inflammatory properties of the leaves and fruits of P. foetida. Methanol (100 %) was used to prepare the plant extracts. The antioxidant activity was determined using total phenolic content (TPC), total flavonoid content (TFC), total alkaloid content (TAC), 2,2-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging, ferric reducing antioxidant power (FRAP), and oxygen radical absorption capacity (ORAC) assays. The anti-diabetic effects of plant extracts were determined by using anti-glycation and anti-amylase inhibitory assays. Cell viability was analyzed by the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl-2H-tetrazolium bromide (MTT) assay. Based on the findings, the leaf extract of P. foetida showed a higher TPC (21.46±1.56 mg GAE/g of extract), TFC (4.25±0.23 mg QE/g of extract), TAC (4.37±6.50 mg/g of extract), DPPH (10.91±1.29 mg TE/g of extract), ABTS+ (105.80±18.62 mg TE/g of extract), FRAP (11.85±1.45 mg TE/g of extract), and ORAC (46.23±3.58 mg TE/g of extract) compared to its fruit extract. The anti-amylase and anti-glycation activities were high in the leaf extract of P. foetida (30.7% and 77.65 % respectively). The fruit extract of P. foetida had the highest cell viability and nitric oxide (NO) production-inhibition in RAW macrophage (264.7 cells) compared to the fruit extract. It can be concluded that P. foetida has good therapeutic properties, and could be a potential source for pharmaceuticals and nutraceuticals industries. |
