| Abstract | The total phenolic contents and the antioxidant activities of methanolic extracts of different parts (fruit, calyx, leaf, stem, and root) of Physalis alkekengi var. francheti were investigated using established in vitro systems including DPPH radical-scavenging, nitrite-scavenging, superoxide anion radical-scavenging activity, measurement of reducing power, and assessment of the metal-chelating effect. The highest extraction yield was from fruit (52.55%), whereas the lowest levels were obtained from root (10.49%) and stem (12.88%).The leaf extract had the highest total phenolic (58.47 mg/g) and total flavonoid (4.83 mg/g) contents, plus the greatest antioxidant activity, as shown by the DPPH radical-scavenging assay, and the highest levels of reducing power at concentrations of 1 and 5 mg/mL. In addition, the calyx also showed good antioxidant activity.These findings indicate that methanolic extracts of leaf and calyx may be useful in the food manufacturing and nutraceutical industries. |
