Comparative Evaluation of Four Extraction Methods of Antioxidant Compounds from Decatropis bicolor in Aqueous Medium Applying Response Surface Design

Abstract

The objective of this paper is to compare conventional, ultrasound, microwave, and French press methods for the extraction of antioxidant compounds from Decatropis bicolor in an aqueous medium. This plant is widely used in Mexican traditional medicine for breast cancer treatment. Despite that, there are few studies on D. bicolor. Two response surface designs were applied to establish the best conditions of the liberation of antioxidants from D. bicolor, which were determined by DPPH• and Ferric Reducing Antioxidant Power (FRAP) techniques. The total phenolic content was evaluated by the Folin-Ciocalteu method. The results showed that D. bicolor is a source of antioxidants (669–2128 mg ET/100 g and 553–1920 mg EFe2+/100 g, respectively) and phenolic compounds (2232–9929 mg EGA/100 g). Among the physical factors that were analyzed, the temperature was the determinant factor to liberate the compounds of interest by using low concentrations of the sample and short times of extraction. The French press was the most efficient method, obtaining values of antioxidant activity and phenolic compounds even higher than those reported by using extraction methods with solvents such as methanol.

“…The size of the steepness and contour ellipticity values exhibited on the response surface can effectively judge the degree of interaction between factors. The steeper the surface, the larger the contour ellipticity (Jaimez-Ordaz et al, 2021;Lin et al, 2020), which represents the strength of the interaction effect. Figure 4 shows that the strength of the interaction effects of BC on hypoglycemic performance was stronger than that of AC and then stronger than that of AB.…”

Encapsulation of Bioactive Phytochemicals in Plant-Based Matrices and Application as Additives in Meat and Meat Products

“…For instance, a recent study demonstrated that USAE treatment improved the extraction of both lipophilic and hydrophilic substances from turmeric, ginger and garlic, including vitamin C, total phenols, flavonoids, non-flavonoids and β-carotene [ 43 ]. Similarly, USAE has been successfully used for the extraction of antioxidant compounds from Decatropis bicolor— a medicinal plant from Central America [ 44 ]. In this study, the authors optimized the extraction conditions, such as extraction time, temperature, and sample size [ 44 ].…”

“…Thus, to limit disruption of the structural integrity and degradation of phytochemicals, the extraction time should be carefully manipulated (shortened) and also extraction cycles can be employed to reduce these degradation processes [ 27 ]. In a recent study, MWAE was used for the extraction of antioxidant compounds from Decatropis bicolor , which showed that this technology dramatically reduced the extraction time and improved the extract activity in comparison with a conventional extraction procedure [ 44 ]. In this study, the authors optimized the extraction conditions, such as MW power (30%), extraction time (2 min), and sample concentration (2%), which led to an extraction that was much faster than the conventional method.…”

“…Las propiedades físicas determinadas fueron: eje mayor, eje menor, espesor, peso, volumen y color. La composición proximal se realizó de acuerdo a la metodología de la AOAC, mientras que el contenido de minerales se determinó de acuerdo a la metodología establecida por la EPA, (Jaimez-Ordaz, J., et al, 2021).…”
