“…These biological activities may permit to reduce the appearance of chronic diseases such as diabetes, arteriosclerosis, Alzheimer's, even against different lines of cancer [153]. In this case, the use of extract encapsulation makes it possible to guarantee the stability of phenolic compounds during food processing, storage [154] and digestion [155].…”

Mangifera indica fruit (mango) is one of the most commercialized fruits around the world, due to the great variety of existing cultivars from which different food products such as drinks, juices, concentrates, and jams are prepared. The wastes generated during the processing of this fruit (20 million tons), which represent up to 60% of the weight of the fruit and consist mainly of peels (12%) and kernels seeds (20%), cause a series of environmental and economic problems for entrepreneurs in the sector. This is because there are no clear policies for its disposal and reuse. Nevertheless, the development of biotechnological tools has led to these wastes becoming subject of interest for their use in multiple industries such as food and pharmaceuticals, since it has been shown that they can be used as raw material to obtain phenolic compounds with biological activities (antioxidant, antimicrobial, anticancer, etc.). This review compiles the most relevant works from 2016 to 2021 about extraction, quantification, identification, biological activities, and applications of phenolic compounds obtained from the mango tree, with special focus on the fruit, with the objective to promote the use of mango from a sustainable perspective, and with a biorefinery approach.

“…GSLs are sulfur-rich secondary metabolites derived from glucose and amino acids. The hydrolysis products of GSLs play important roles in plant defense and exhibit biological activities that can benefit human health [ 7 , 8 ]. Brassicaceae vegetables, especially broccoli, are rich sources of GSLs [ 9 ].…”

Preharvest Methyl Jasmonate Treatment Increased Glucosinolate Biosynthesis, Sulforaphane Accumulation, and Antioxidant Activity of Broccoli

et al. 2022

Broccoli is becoming increasingly popular among consumers owing to its nutritional value and rich bioactive compounds, such glucosinolates (GSLs) and hydrolysis products, which are secondary metabolites for plant defense, cancer prevention, and higher antioxidant activity for humans. In this study, 40 μmol/L methyl jasmonate (MeJA) was sprayed onto broccoli from budding until harvest. The harvested broccoli florets, stem, and leaves were used to measure the contents of GSLs, sulforaphane, total phenolics, and flavonoids, as well as myrosinase activity, antioxidant activity, and gene expression involved in GSL biosynthesis. The overall results revealed that GSL biosynthesis and sulforaphane accumulation were most likely induced by exogenous MeJA treatment by upregulating the expression of CYP83A1, SUR1, UGT74B1, and SOT18 genes. Exogenous MeJA treatment more remarkably contributed to the increased GSL biosynthesis in broccoli cultivars with low-level GSL content (Yanxiu) than that with high-level GSLs (Xianglv No.3). Moreover, MeJA treatment had a more remarkable increasing effect in broccoli florets than stem and leaves. Interestingly, total flavonoid content substantially increased in broccoli florets after MeJA treatment, but total phenolics did not. Similarly, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity, trolox-equivalent antioxidant capacity (ABTS), and ferric-reducing antioxidant power (FRAP) were higher in broccoli floret after MeJA treatment. In conclusion, MeJA mediated bioactive compound metabolism, had positive effects on GSL biosynthesis, sulforaphane, and flavonoids accumulation, and showed positive correlation on inducing higher antioxidant activities in broccoli floret. Hence, preharvest supplementation with 40 μM MeJA could be a good way to improve the nutritional value of broccoli florets.

“…The type of broccoli is Salio 55, which is harvested 55 days after spring setting and 63 days after autumn setting under suitable conditions. As described in previous studies (Radunz et al, 2021), the broccoli microgreens were ground into a powder by a pestle in a mortar with liquid nitrogen, then lyophilized (scient2‐10NIA, Xinzhi, China), and pulverized by a grinder until it can be used directly for gavage. Powder of broccoli microgreens and phosphate buffer saline (PBS) were mixed to form a 2 g/ (kg bw) suspension, and then was diluted partly to a concentration of 0.2 g/ (kg bw) and stored at −20°C.…”

This study aims to explore the hypoglycemic effect of lyophilized broccoli microgreens on type 2 diabetes (T2D) in mice. The experiment lasted 18 weeks, including 1 week of adaptation (normal diet) and 17-week experimental period (high-fat diet). After ingestion of broccoli microgreens, the body weight and glucose homeostasis were improved. Meanwhile, the blood lipid status, antioxidant indexes, and inflammatory factors level were improved. Moreover, the insulin resistance and the pathological changes in mice organs were reversed. In addition, the composition of gut microbiota and the production of propionic acid in intestinal content were improved. Our experiment proved that broccoli microgreens have the ability to regulate T2D and improve symptoms of mice T2D induced by high-fat diet and streptozotocin (STZ). Practical applicationsFor years, the functionality of broccoli microgreens has attracted much attention. This article will prove the therapeutic effect of broccoli microgreens on T2D and explain its principle of action in the management of T2D.
