Effects of process conditions on the ultrasonic extraction of phenolics scavenger from Curcuma caesia rhizome

Medicinal properties of Malaysian Curcuma caesia have not been studied extensively, even though it has been used as a traditional remedy. This study examined the effects of various extraction temperatures (30, 40, 50, 60, 70o C) using a high frequency (40 kHz) ultrasonic extraction method, time...
