“…Two novel derivatives of delphinidin were recorded latterly in the purple Chinese(delphinidin-3-glucoside-5-dirhamnoside and delphinidin-3-glucoside-5-dirhamnoside) [28]. There are differentfrom all the delphinidin derivatives identified before in other cultivars/varieties around the world [29].…”

Eggplant is one of the common Egyptian medicinal plants, which belongs to family Solanaceae. All parts of the plant i.e., fruits, stem, leaf,root and flower are used for the curative of great number of diseases. For the present investigation, peels of white and black eggplant were selected for total phenolic, peroxidation antioxidants and antimicrobial activity. The antimicrobial activity of two different of ethanol extract of peel Eggplant was screened against two Gram negative bacteria, Escherichia coli and Pseudomonas aeruginosa, two Gram positive bacterium, Staphylococcus aureus and Bacillus subtilus. Also three species of fungi i.e., Candida albicans, Aspergillus flavus and Aspergillus niger were used by well and disc diffusion methods. Phytochemical investigation of the eggplant peel extracts showed antioxidants activity. However, the phenolic content of peel black eggplant was much greater than the white eggplant. White eggplant peel extract inhibition the linoleic acid peroxidation than that of black eggplant through 7 days. Ethanol extract of peel black Eggplant exhibited dose dependent significant inhibitory activities against both bacterial and fungal strains are tested concentrations.

The aim of this study was to see the effectiveness of Solanum melongena peel extract in the treatment of arsenic-induced Bowen’s disease. In total 8 patients of arsenic-induced Bowen’s disease were selected from the two arsenic-endemic areas. The peel extract containing ointment was provided to each patient and instructed him/her to apply twice daily on the site of the lesion for 12 weeks. The measurement of the lesion size as well as photograph were collected both before and at the end of the study. The mean (± SD) diameter of the lesion was 3.8 ± 1.9 cm which reduced to 2.5 ± 1.7 cm (reduction 34%). The result was statistically significant.

“…Accordingly, Singh et al [51] reported eggplant contain chlorogenic acids, with traces of quercetin and myricetin glucosides. Hydroxycinnamic acid conjugates were peculiar of the whole eggplant and pulp [44]; however, chlorogenic acid, ferulic acid and caffeic acid were also found in the eggplant peel [38,52]. A complex flavonol profile was described for eggplant skin samples [49], in spite of a low amount in the pulp [51].…”

DR2B and DR2C extracts, from peel of commercially and physiologically ripe eggplants, were studied for the antioxidative cytoprotective properties and anti-HSV-1 activity, in line with the evidence that several antioxidants can impair viral replication by maintaining reducing conditions into the host cells. The antioxidative cytoprotective effects against tBOOH-induced damage was assessed in Caco2 cells, while the antiviral activity was studied in Vero cells; phenolic and anthocyanin fingerprint was characterized by integrated phytochemical methods. Results highlighted different compositions of the extracts, with chlorogenic acid and delphinidin-3-rutinoside as the major constituents; other peculiar phytochemicals were also identified. DR2C resulted able to partly counteract the tBOOH-induced cytotoxicity, with a remarkable lowering of lactate metabolism under both normoxia and hypoxia. DR2B and DR2C reduced ROS production, possessed scavenging and chelating properties. Interestingly, DR2C increased intracellular GSH levels. Furthermore, DR2Cinhibited the HSV-1 replication when added for 24 h after viral adsorption, as also confirmed by the reduction of many viral proteins expression. Since DR2C was able to reduce NOX4 expression during HSV-1 infection, its antiviral activity may be correlated to its antioxidant properties. Although further studies are needed to better characterize DR2C activity, the results suggest this extract as a promising new anti-HSV-1 agent.
