| Summary: | 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, % inhibition of DPPH˙ and ABTS˙+
free radicals) of extracts
were determined using complete randomised design (CRD). The results showed that the CEY
and RSA of extracts significantly affected by independent variables. The maximum value of
CEY (97.14±0.36 mgg-1), scavenging of DPPH˙ radicals (32.12 ± 0.38%) and scavenging of
ABTS˙+ radicals (40.52±0.73%) were obtained at the combined treatment conditions of 75%,
55°C and 40 min. The UAE results obtained were compared with those achieved by using
conventional Soxhlet extraction (CSE) method. It was found UAE allowed extraction at lower
temperature and the extracts obtained posses higher quality compare with CSE. UAE is a
promising environment friendly technique for the extraction of bioactive compounds from
winter melon (Benincasa hispida) seeds. |
