“…Recently, research on predicting the contents of total phenolics, anthocyanins and the antioxidant capacity of 13 fruits and vegetables, using colorimetric coordinates, was carried out (Vieira et al, 2019). Equations with r 2 of 0.99 to predict the content of total anthocyanins were obtained, however, they demonstrated that it was not possible to predict the content of total phenolics and the antioxidant capacity through colorimetry.…”

“…Equations with r 2 of 0.99 to predict the content of total anthocyanins were obtained, however, they demonstrated that it was not possible to predict the content of total phenolics and the antioxidant capacity through colorimetry. The reason may be because they used a larger variety of fruits and vegetables, and the prediction was only studied for crude, diluted or non-diluted phenolic extracts (Vieira et al, 2019).…”

The food industry should have methods that allow identifying bioactive compounds quickly, efficiently and at low cost. The objective of this research was to obtain mathematical models for predicting the amount of total phenolics, anthocyanins and antioxidant capacity of blackberry, blueberry and jaboticaba skin, based on colorimetric parameters (L*, a*, b*, C* and h*). All analyses were done in the phenolic extracts obtained from these fruits. The mathematical models were obtained through multiple linear regression using the stepwise method. The significant correlation between the colorimetric parameters and chemical analyses resulted in models with a high predictive ability (high r 2), such as in the determination of the contents of anthocyanins (r 2 = 0.99), total phenolics (r 2 = 0.86) and for the antioxidant capacity (r 2 = 0.99). Thus, the prediction of levels of these bioactives compound, using colorimetric parameters, is very promising for cost and time savings.

“…Anthocyanin content depends on the cultivar, environmental factors and growth, and storage conditions [ 43 ]. Table 1 shows that the major anthocyanin in Corni fructus extracts for the cultivars Bostraszycki , Florianka , and Słowianin was pelargonidin 3- O -glucoside ranging from 2.21 ± 0.19 to 3.09 ± 0.25 mg/g.…”

As a systemic disease, diabetes mellitus (DM) is characterized by the disruption of many glucose metabolic pathways. Therefore, it seems critical to study new therapies to support treatment to develop therapeutic systems that can operate across a broad metabolic spectrum. The current state of knowledge indicates an essential role of the gut microbiota in the development and course of the disease. Cornus mas fruits have demonstrated a rich biological activity profile and potential for application in the treatment of DM. As part of a preliminary analysis, the activity of four cultivars of Cornus mas fruits was analyzed. The cultivar Wydubieckij was selected as having the highest activity in in vitro conditions for further prebiotic system preparation. The study aimed to develop a unique therapeutic system based, first of all, on the mechanism of α-glucosidase inhibition and the antioxidant effect resulting from the activity of the plant extract used, combined with the prebiotic effect of inulin. The obtained system was characterized in vitro in terms of antioxidant activity and enzyme inhibition capacity, and was then tested on diabetic rats. The study was coupled with an analysis of changes in the intestinal microflora. The system of prebiotic stabilized Cornus mas L. lyophilized extract with inulin offers valuable support for the prophylaxis and treatment of DM.

The PyPIF5-PymiR156a-PySPL9-PyMYB114/MYB10 module regulates light-induced anthocyanin biosynthesis in red pear

Some cultivars of pear (Pyrus L.) show attractive red fruit skin due to anthocyanin accumulation. This pigmentation can be affected by environmental conditions, especially light. To explore the light-induced regulation network for anthocyanin biosynthesis and fruit coloration in pear, small RNA libraries and mRNA libraries from fruit skins of ‘Yunhongyihao’ pear were constructed to compare the difference between bagging and debagging treatments. Analysis of RNA-seq of fruit skins with limited light (bagged) and exposed to light (debagged), showed that PyPIF5 was down-regulated after bag removal. PymiR156a was also differentially expressed between bagged and debagged fruit skins. We found that PyPIF5 negatively regulated PymiR156a expression in bagged fruits by directly binding to the G-box motif in its promoter. In addition, PymiR156a overexpression promoted anthocyanin accumulation in both pear skin and apple calli. We confirmed that PymiR156a mediated the cleavage of PySPL9, and that the target PySPL9 protein could form heterodimers with two key anthocyanin regulators (PyMYB114/PyMYB10). We proposed a new module of PyPIF5-PymiR156a-PySPL9-PyMYB114/MYB10. When the bagged fruits were re-exposed to light, PyPIF5 was down-regulated and its inhibitory effect on PymiR156a was weakened, which leads to degradation of the target PySPL, thus eliminating the blocking effect of PySPL on the formation of the regulatory MYB complexes. Ultimately, this promotes anthocyanin biosynthesis in pear skin.
