Conventional and non-conventional extraction of functional compounds from jiotillaON NI (Escontria chiotilla) fruits and evaluation of their antioxidant activity

There is a growing interest in obtaining bioactive compounds from underexplored plant organisms such as jiotilla (Escontria (Biodegradation modeling of sludge bioreactors of total petroleum hydrocarbons wea hering in soil chiotilla), a species of the Cactaceae family whose fruit is a source of betalains and phenolic compounds. Therefore, it is relevant s ime ) to establish an extraction methodology that allows a higher yield of bioactive compounds and greater functional activity to be obtained. In this study, the conventinal extraction process was optimized to obtain betaains, phenolic compounds, and SA. Medina-Moreno, S. Huerta-Ochoa, C.A. Lucho-Constantino, L. Aguilera-azquez, A Jimenez -antioxidant activity from jiotilla xtracts and esults were compared with those obtained by ultrasound-assisted and ultrasound -Gonzalez y M Gutierrez-Rojas microwave extraction. Optimum conditions for conventional extraction of betalains (90.56 +/- 0.88 mg/100 g fresh weight (g f w)) 259 C e i i to sob i e i ad t io de Bifid b t i i f ti a dicione a ida and phenolic compounds (129.12 +/- 14.21 mg/100 gfw) were 37.5% v/v ethanol, an m:v ratio of 1:20, and 40 min maceration with shaking. Ultrasound-assisted extraction increasethe phenolic compound content f the extracby 34.01% and its antioxidant (Growth survival and adaptaton of Bifidobacterium infantis o acidic condit on ) activity by 25.68%, a positive correlation being found between these parameters. Ultrasound-microwave extraction did not L M g R y P B e Ca il A. Guie N a E B a Fl id A A ol improve extraction yields compared to the other two technologies. These results show that the extraction method affects the content of functional compounds and antioxidant activity and pinpoint that jiotilla fruits can be a viable alternative for extraction Espino a of betalains and phenolic compounds.
