“…In this regard, scavenging of free radicals initiates the oxidation mechanism and inhibits the chain reaction, thus preventing the lipid oxidation (Liu, Wu, Weng, & Tseng, 2005). There are different methods for measuring the antioxidant activity.…”

The present study aimed to investigate the effects of ultrasound-assisted extraction (UAE) condition on the yield, antioxidant activity and stability of the oil from papaya seed. The studied ultrasound variables were time, temperature, ultrasound power and solvent to sample ratio. The main goal was to optimise UAE condition providing the highest recovery of papaya seed oil with the most desirable antioxidant activity and stability. The interaction of ultrasound variables had the most and least significant effects on the antioxidant activity and stability, respectively. Ultrasound-assisted extraction provided a relatively high oil recovery (∼ 73%) from papaya seed. The strongest antioxidant activity was achieved by the extraction at the elevated temperature using low solvent to sample ratio. The optimum ultrasound extraction was set at the elevated temperature (62.5 °C) for 38.5 min at high ultrasound power (700 W) using medium solvent to sample ratio (∼ 7:1 v/w). The optimum point was practically validated.

“…Total antioxidant activity of all the extracts was measured in the concentration of 10-1000 mg mL À1 (Liu, Yi-Wu, Weng, & Tseng, 2005). Briefly, peroxidase (4.4 unit mL À1 , 0.2 mL), H 2 O 2 (50 mM, 0.2 mL), ABTS (2,2 0 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), 100 mM, 0.2 mL) and distilled water (1.4 mL) were mixed and kept in dark for 1 h to form a bluish green complex.…”

In this study, the ethanol extract of Momordica dioica fruit extract (200 mg kg(-1)) was studied for nephroprotective and curative activities. Chloroform, ethyl acetate, ethanol and aqueous extracts were prepared. In vitro antioxidant activity was made the basis for the selection of the ethanol extract for further studies. In DPPH free radical scavenging activity, the ethanolic extract has shown maximum inhibition (84.2%), followed by aqueous (74.8%), ethyl acetate (69.4%) and chloroform (59.7%) extract. On the other hand, in total antioxidant activity, the ethanol extract has shown 80.1% inhibition, followed by aqueous (71.9%), ethyl acetate (67.2%) and chloroform (53.2%) extracts. A single dose (5 mg kg(-1), i.p.) of cisplatin was administrated to induce nephrotoxicity. Blood urea and serum creatinine were analysed as biochemical markers of nephrotoxicity. Reduced glutathione (GSH) and the product of lipid peroxidation (MDA) were also measured in kidney tissues. A single dose of cisplatin resulted in significant reduction in body weight and increased the urea and creatinine levels. Extract administration has shown significant recovery in the levels of these biochemicals in curative (p < 0.001) and protective groups, whereas a single dose of cisplatin caused significant reduction in GSH and an increase in malondialdehyde production. Recovery was observed in treated groups. This study suggested that the nephroprotective and curative activities of M. dioica fruit extract are due to its antioxidant activity. It is further concluded that this antioxidant activity may be attributed to the phenolics, flavonoids and amino acids present in the extract.

“…At low power and high frequencies, it can be used to determine emulsions [1], to monitor particle-size distribution [2][3][4], to investigate biological properties [5], and to supervise the real-time analysis of chemical reactions [6]. At high power and low frequencies, ultrasound can be used for the processes of cleaning, which is the most industrially developed application [7], emulsification [8][9][10], precipitation [11][12][13], extraction [14][15][16], waste water treatment [17] and chemical reactions [18][19][20][21].…”
