The milpa system is a biocultural polyculture technique. Heritage of Mesoamerican civilizations that offers a wide variety of plants for food purposes. Corn, common beans, and pumpkins are the main crops in this agroecosystem, which are important for people’s nutritional and food security. Moreover, milpa system seeds have great potential for preventing and ameliorating noncommunicable diseases, such as obesity, dyslipidemia, type 2 diabetes, among others. This work reviews and analyzes the nutritional and health benefits of milpa system seeds assessed by recent preclinical and clinical trials. Milpa seeds protein quality, vitamins and minerals, and phytochemical composition are also reviewed. Evidence suggests that regular consumption of milpa seeds combination could exert complementing effect to control nutritional deficiencies. Moreover, the combination of phytochemicals and nutritional components of the milpa seed could potentialize their individual health benefits. Milpa system seeds could be considered functional foods to fight nutritional deficiencies and prevent and control noncommunicable diseases.
Anthocyanins (ANCs) are naturally occurring water-soluble pigments responsible for conferring red, blue, and purple colors to fruits, vegetables, flowers, and grains. Due to their chemical structure, they are highly susceptible to degradation by external factors, such as pH, light, temperature, and oxygen. Naturally acylated anthocyanins have proven to be more stable in response to external factors and exhibit superior biological effects as compared with their non-acylated analogues. Therefore, synthetic acylation represents a viable alternative to make the application of these compounds more suitable for use. Enzyme-mediated synthetic acylation produces derivatives that are highly similar to those obtained through the natural acylation process, with the main difference between these two pathways being the catalytic site of the enzymes involved in the synthesis; acyltransferases catalyze natural acylation, while lipases catalyze synthetic acylation. In both cases, their active sites perform the addition of carbon chains to the hydroxyl groups of anthocyanin glycosyl moieties. Currently, there is no comparative information regarding natural and enzymatically acylated anthocyanins. In this sense, the aim of this review is to compare natural and enzyme-mediated synthetic acylated anthocyanins in terms of chemical stability and pharmacological activity with a focus on inflammation and diabetes.
This work aimed to obtain and characterize anthocyanin-rich extracts (ARE) from native black beans and evaluate their antioxidant and anti-inflammatory potential. The initial extract was obtained by supercritical fluids (RE) and purified using Amberlite® XAD-7 resin (PE). RE and PE were fractionated using countercurrent chromatography, and four fractions were obtained (REF1 and REF2 from RE, PEF1, and PEF2 from PE). ARE and fractions were characterized, and the biological potential was evaluated. ABTS IC50 values ranged from 7.9 to 139.2 (mg C3GE/L), DPPH IC50 ranged from 9.2 to 117.2 (mg C3GE/L), and NO IC50 ranged from 0.6 to143.8 (mg C3GE/L) (p < 0.05). COX-1 IC50 ranged from 0.1 to 0.9 (mg C3GE/L), COX-2 IC50 ranged from 0.01 to 0.7 (mg C3GE/L), and iNOS IC50 ranged from 0.9 to 5.6 (mg C3GE/L) (p < 0.05). The theoretical binding energy for phenolic compounds ranged from −8.45 to −1.4 kcal/mol for COX-1, from −8.5 to −1.8 kcal/mol for COX-2, and from −7.2 to −1.6 kcal/mol for iNOS. RE and REF2 presented the highest antioxidant and anti-inflammatory potential. Countercurrent chromatography effectively isolates and purifies bioactive compounds while maintaining their biological potential. Native black beans present an attractive phytochemical profile and could be used as ingredients in nutraceuticals and functional foods.
Objectives The objective of this work was to evaluate anti-inflammatory and antioxidant potential of black bean (Phaseolus vulgaris L.) phenolic extract. Methods Supercritical fluid extraction was used to obtain a water-ethanol 50% v/v phenolic extract from black beans. Total phenolic content (TPC) and total anthocyanin content (TAC) were quantified. Mass spectrometry analysis was used for compounds identification. Antioxidant potential was evaluated using radicals DPPH and ABTS inhibition assays. The extract was tested for Cyclooxygenase-2 human recombinant (COX-2) and nitric oxide synthase (NOs) inhibition assays. Results TPC was 44.31 ± 1.91 mg GAE/g dry coat and TAC was 2.46 ± 0.04 mg C3GE/g dry coat. Ferulic, caffeic, p-coumaric, chlorogenic acids, rutin, glycitein, catechin, myricetin, kaempferol, cyanidin-3-glucoside, delphinidin-3-glucoside, petunidin-3-glucoside and malvinidin-3-glucoside were identified. DPPH assay IC50 was 143.8 ± 2.76 mg GAE/g dry coat and for to ABTS assay was 1.197 ± 0.01 mg GAE/g dry coat. Furthermore, Black beans phenolic extract inhibited COX-2 and NOs enzymes activity by 30.63 ± 0.73% and 32.33 ± 2.9%, respectively. Conclusions Phenolic compounds from endemic Mexican black present antioxidant and anti-inflammatory potential. These beans could be used in the development of functional foods.
