The effect of extraction temperature on total phenolic contents and free radical scavenging activity of Gynura procumbens leaf extract was investigated. The content of total phenolic were not significantly different (P > 0.5) at the extraction temperature of 40 C and 50 C. However, decrease in total phenolic content was observed from extraction temperature of 60 C and above. The extracts obtained at lower temperature exhibited significant free radical-scavenging activity compared to extraction at higher temperatures.
