Physalis alkekengi (Solanaceae) is a rich source of different antioxidants, which has been advised for the treatment of various diseases such as inflammation and rheumatism. In this paper, antioxidant properties of different parts of P. alkekengi including leave, calyx, green and orange fruits randomly collected from around the Tonekabon-Iran were studied. Antioxidant activity of extract was measured with DPPH radical scavenging activity, inhibition of fatty acid oxidation and ferric-reducing antioxidant power. Also, the total phenol, flavonoid, quercetin, luteolin, anthocyanin and carotenoid contents of samples were determined. The tests were conducted in a completely randomized design with 4 replications. The leaves of P. alkekengi contained the most content of the total phenol, flavonoid and ferric-reducing antioxidant power. The maximum of DPPH radical scavenging activity (1.81±0.214 g/gFW), peroxidation fatty acid inhibition (75.53±5.35 %), and total carotenoids content (10.05±1.45 mg/gFw) were observed in orange fruit of P. alkekengi. The highest value of luteolin was measured in the leaves of green fruit stage, and it was 0.198±0.001 mg/gDW. Querccetin was found only in the leaves of vegetative and flowering stages, 9.2±0.05 and 9±0.53 μg/gDw respectively.
