Abstract
Sorghum (Sorghum bicolor L. Moench) has been sparsely used as human food due to certain anti-nutritional factors such as tannins that reduce its digestibility, although the grain is an important source of bioactive compounds such as phenolic compounds (PCs). This study aimed to assess the impact of cooking and alkaline cooking (nixtamalization) on the bioaccessibility and antioxidant capacity of PCs of two sorghum varieties (white/red). Nixtamalization was the most effective procedure for the reduction of tannins (74.3%). Gallic acid proved to be the most bioaccessible PC (6359 μg/g). The total phenolics and condensed tannins correlated with the antioxidant capacity (ABTS/DPPH; R2: 0.30-0.43, p < 0.05). These results confirm the potential of thermal procedures to significantly modify the bioaccessibility of sorghum compounds, enhancing their concentrations and reducing anti-nutritional factors (tannins) while improving their antioxidant capacity.

Abstract
Moringa (Moringa oleifera) is a plant that has generated great interest in recent years because of its attributed medicinal properties. The aim of this study was to characterize the bioactive compounds of moringa leaves (MO) and evaluate their effect on a colorectal carcinogenesis model. Twenty-four male CD-1 mice were divided into 4 groups: Group 1 fed with basal diet (negative control/NC); Group 2 received AOM/DSS (positive control); Groups 3 and 4 were fed with basal diet supplemented with moringa leaves (2.5% w/w and 5% w/w, respectively) for 12weeks. Moringa leaves exhibited a high content of dietary fiber (~18.75%) and insoluble dietary fiber (2.29%). There were identified 9 phenolic compounds whereas the chlorogenic and ρ-coumaric acid showed the higher contents (44.23-63.34μg/g and 180.45-707.42μg/g, respectively). Moringa leaves decreased the activity of harmful fecal enzymes (β-glucosidase, β-glucuronidase, tryptophanase and urease up to 40%, 43%, 103% and 266%, respectively) as well tumors incidence in male CD1-mice (~50% with 5% w/v of moringa dose). These findings suggest that the bioactive compounds of moringa such as total dietary fiber and phenolic compounds may have chemopreventive capacity. This is the first study of the suppressive effect of moringa leaves in an in vivo model of AOM/DSS-induced colorectal carcinogenesis.

Abstract
Biological properties of fruits of Lycium barbarum (goji berries) have been ascribed to their high content of nutrients and phenolics. Comprehensive studies aimed at unambiguously identifying the phenolic components in goji berries are still lacking. In this paper, we report on the isolation and NMR-based identification of the major phenolics in commercially available goji berries. Together with already known phenolics, including caffeic acid, p-coumaric acid, rutin, scopoletin, N-trans-feruloyl tyramine, and N-cis-feruloyl tyramine, an unreported N-feruloyl tyramine dimer was characterized as the most abundant polyphenol isolated from the berries. Usually divalent molecules show enhanced biological activities than their corresponding monomers.
