    Abstract:
    BACKGROUND: Sphaeranthus amaranthoides commonly known as sivakaranthai is used in folklore medicine for the treatment of skin diseases. METHODS: The antioxidant activity of the extract and its fraction was evaluated by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, total antioxidant capacity, and total phenolic content. The tested plant extracts showed variable degrees of antioxidant activity. In the present study, methanolic extract of the whole plant of S. amaranthoides and a flavonoid fraction obtained from column chromatography were studied for wound healing activity by incorporating the sample in simple ointment base. Wound healing activity was studied in excision wound model in rats, following which, wound contraction, period of epithelization, hydroxyproline content, and collagen levels in the scab were studied. RESULTS: Methanolic extract showed the highest antioxidant effect (72.05%) and diethyl ether extract has the least (29.34%) compared to the standard (74.53%). Treatment of wound with ointment containing 5% (w/w) methanolic extract and 5% (w/w) flavonoid fraction exhibited better wound healing activity than positive control (silver sulfadiazine). Finally, histopathology studies conformed wound healing activity in Sphaeranthus amaranthoides. The methanolic extract and flavonoid fraction exhibited good wound healing activity probably due to the presence of phenolic and flavonoid constituents. The methanolic extract and flavonoid fraction significantly enhanced the rate of wound contraction and the period of epithelialization comparable to silver sulfadiazine.
