Antioxidant Activity of the Flower of Nyctanthes arbor tristis L.

Padma S Vankar
Nyctanthes arbor-tristis (Harshingar, Parijat) belongs to the family Oleaceae. The flower has white petals with an orange calyx. Nyctanthes stems have been found to be a rich source of antioxidant. The aqueous extracts of the flower, calyx and petals were evaluated and found to be dose-dependent and showed an increase in DPPH free radical scavenging activity in vitro. The extracts, which showed strong DPPH radical scavenging activity, are in the order Calyx > flower > petals. This signifies that the main antioxidant activity is in the orange colored calyx of the flower. We have attempted an innovative study with the Nyctanthes flower as a part of an exploration for a cheap natural source of antioxidants which can be used at the industrial scale of the food industry.
