“…On the other hand, the main products such as phenylacetic acid and phenylpropionic acid series found in other related studies were not detected in current study. The most significant difference between the two kinds of substances was that the organic acid on the phenyl group of the former substance was alkene acid while that of the latter substance was alkane acid [ 30 , 32 , 33 ]. This may result from the difference in the composition of LPPCs in the samples.…”

In order to enhance the efficient utilization of polymeric proanthocyanidins from litchi pericarp, a process for transforming litchis’ polymeric proanthocyanidins (LPPCs) by using Lactobacilli has been established for products with highly antioxidative properties. Lactobacillus plantarum was selected to enhance the transformation effect. The transformation rate of LPPCs reached 78.36%. The content of litchis’ oligomeric proanthocyanidins (LOPCs) in the products achieved 302.84 μg grape seed proanthocyanidins (GPS)/mg DW, while that of total phenols was 1077.93 gallic acid equivalents (GAE) μg/mg DW. Seven kinds of substances have been identified in the products by using the HPLC-QTOF-MS/MS method, among which 4-hydroxycinnamic acid, 3,4-dihydroxy-cinnamic acid, and proanthocyanidin A2 were major components. The in vitro antioxidative activity of the products after transformation was significantly (p < 0.05) higher than those of LOPCs and LPPCs. The scavenging activity of the transformed products for DPPH free radicals was 1.71 times that of LOPCs. The rate of inhibiting conjugated diene hydroperoxides (CD-POV) was 2.0 times that of LPPCs. The scavenging activity of the products for ABTS free radicals was 11.5 times that of LPPCs. The ORAC value of the products was 4.13 times that of LPPCs. In general, this study realizes the transformation of polymeric proanthocyanidins into high-activity small-molecule substances.

“…These positive impacts may be due to the presence of cinnamic acid, coumaric acid, and ferulic acid with high concentrations in orange peel extract as stated in Table 3. Coumaric acid's hydroxyl group on a benzene ring can react with ROS by donating hydrogen and creating a radical form of coumaric acid with an unpaired valence electron on the oxygen atom, breaking free radical chain reactions (Ulrih et al, 2021). Another important role played by cinnamic and coumaric acids, is their ability to chelate transition metals like copper or iron, which act as catalysts in the generation of free radicals that cause lipid peroxidation, and DNA damage (Gaspar et al, 2009).…”

he present study was conducted to investigate the effects of feeding corn silk, orange peel, and pomegranate peel extracts on semen quality, blood biochemical constituents, antioxidants capacity of male New Zealand White rabbits under heat stress conditions. In an experiment that lasted 8 weeks, thirty male rabbits aged twenty-four weeks with an average body weight of 2.85±0.1kg were randomly distributed into five equal groups (6 rabbits/ group). Each rabbit was kept in an individual cage. The first group (control) was fed a basal diet. The second group (positive control) was fed the basal diet supplemented with vit E. at a level of 250 ppm. The third, fourth, and fifth groups were fed the basal diet supplemented with corn silk, orange peel, and pomegranate peel extracts at a level of 150 ppm, respectively. Experimental diets were offered ad-libitum and clean drinking water was freely available. The overall average of ambient temperatures and relative humidity were 31.1°C and 62.5%, respectively. Overall temperature-humidity index (THI) through the experimental period was 29.14 indicating severe heat stress conditions. According to the results of the HPLC screening for the different extracts: ferulic acid, cinnamic acid and coumaric acid were the most abundant polyphenols in orange peel extract, while gallic acid was the most abundant polyphenol in pomegranate peel extract. Semen quality parameters improved in rabbits of orange peel and corn silk groups, opposite to rabbits fed pomegranate peel extract. The activity of seminal catalase and glutathione peroxidase increased in rabbits fed orange peel and corn silk extracts. Blood total proteins, albumin, globulins and creatinine were not affected by different antioxidants supplements. Serum total antioxidants capacity, catalase and superoxide dismutase were significantly increased in all experimental groups compared with the control. In conclusion, the current results showed that using orange peel or corn silk extracts as feed supplements at a level of 150ppm could improve semen quality as well as antioxidants capacity of male rabbits reared under heat stress conditions.
