Ultrasound-assisted extraction of valuable compounds from winter melon (Benincasa hispida) seeds

Ultrasound-assisted extraction of valuable compounds from winter melon (Benincasa hispida) seeds

Ultrasound-assisted extraction (UAE) was applied for the extraction of bioactive valuable compounds from winter melon (Benincasa hispida) seeds. Effects of amplitude (25-75%), temperature (40-60°C) and sonication time (20-60 min) on crude extraction yield (CEY) and radical scavenging activities (RSA...
