“…Comparable outcomes of phenolic compounds were obtained by [16], and high contents in this present study were slightly lower than those reported in the literature. is discrepancy may be due to the existence of various amounts of sugars, ascorbic acid or carotenoids or the duration, extraction strategies, or geographical variation, which might also regulate the formation of phenolic aggregates [33]. As reported in a previous study, compared with other plant species, jute leaves have much higher amounts of total polyphenol contents in Paederia foetida leaves containing 4.96 mg GAE/g [34], and 109.21-116.70 mg/100 g in sorghum [35].…”

In addition to fiber, Corchorus (jute) leaf is also rich in secondary metabolites and is used in folk medicine in jute-producing communities. It has been reported that jute halts progression of and helps manage different chronic diseases like tumors, obesity, diabetes, and cardiovascular diseases. Various phytochemical, mineral, and antioxidant potency properties of 30 genotypes belonging to Corchorus capsularis and Corchorus olitorius were evaluated in the current study. The results demonstrate that the range of total flavonoids and polyphenols was 3.04 to 13.66 mg rutin equivalent (RE)/g and 5.12 to 7.78 mg gallic acid equivalent (GAE)/g DW, respectively. Total tannin and saponin content in both species was 13.08 to 26.95 mg tannic acid (TAE)/g and 34.45 to 114.59 mg tea saponin (TSE)/g DW, respectively, when analyzed for the first time. Moreover, this study sincerely establishes that jute leaf is a great source of mineral elements (magnesium, zinc, and selenium) and could also be a good energy source. The antioxidant properties of samples were examined with three unique strategies, including DPPH, FRAP, and ABTS values of leaf extract ranging from 206.42 to 351.77 μg/ml (IC50), 16.69 to 94.69 mmol Fe (II)/g DW, and 50.27 to 149.90 mmol trolox equivalent (TE)/g DW, respectively. A principle component analysis (PCA) explained 58.52% of the variance, while a hierarchical cluster analysis (HCA) was performed to construct five distinct groups based on their secondary compound metabolites content and antioxidant activities. Therefore, this study facilitates selection of the high genotypes that might be used as new materials for developing industrial and medicinal uses in addition to sorting genotypes for future genetic engineering purposes in order to enhance a particular bioactive compound and its natural antioxidants that are beneficial for human health.

“…Resveratrol, a natural polyphenolic, non-flavonoid antioxidant (trans-3, 40, 5-trihydroxystylben), is a phytoalexin which has high levels of food products, especially red wine made from grapes (Sayin et al 2017). The antioxidant properties of plant extracts containing phenol group have been shown in previous studies (Burri et al 2017;Zhang et al 2018). Resveratrol has important anti-inflammatory, antioxidant and immunomodulatory properties (Soufi et al 2012).…”

Methotrexate (MTX) is a commonly used folic acid antagonist for the treatment of neoplasia and some autoimmune diseases. Resveratrol has important anti-inflammatory, antioxidant and immunomodulatory properties. The aim of this study was to investigate the effects of resveratrol on MTX-induced ovary-damage and oxidative stress in rats. We hypothesized that supplement of resveratrol could counteract MTX-induced cytotoxicity in rat ovary. Albino Wistar female rats were randomly divided into three groups: Healthy control (HC), resveratrol + methotrexate (RMTX) and methotrexate (MTX) group. Their ovaries were removed. Biochemical and histopathological methods were utilized for evaluation of the oxidative ovary-damage. MDA was found to be higher but tGSH and SOD were lower in the ovarian tissue of the rat group administered MTX, but it is observed that these ratios are reversed in HC and in RMTX groups. MTX treatment induced ovary damage and especially pre-treatment with resveratrol provided protective effect against this MTXinduced ovary-damaged.

“…Phenolic compounds such as gallic acid, catechin, and epicatechin are notoriously endowed with antioxidants, astringents, and antimicrobial activity. Therefore, such species are subject of increasing interest in various fields such as pharmaceuticals, leather tanning, cosmetics, and the food industry [7][8][9][10][11]. Low-molecular-weight hydroxybenzoic acids and some of their derivatives can be obtained from wood extractives and via induced lignin degradation [12,13].…”

Low-Molecular-Weight Phenols Recovery by Eco-Friendly Extraction from Quercus Spp. Wastes: An Analytical and Biomass-Sustainability Evaluation

In this work, chemical–physical protocols aimed at the implementation of eco-friendly and biomass-sustainable recovery processes of useful compounds from forestry and/or wood industry wastes were evaluated. Four species of interest in industrial and environmental fields (Quercus cerris, Quercus ilex, and Robinia pseudoacacia from Central Italy, Quercus petraea from France) were submitted to neutral extraction and analyzed by gaschromatography, with mass spectrometry identification of low-molecular-weight phenols. Moreover, Quercus petraea heartwood samples were submitted to three extraction/hydrolysis protocols in an alkaline environment, and the byproducts from the lignin degradation were identified and evaluated. The recovery of bioactive phenols from forestry wastes by applying eco-friendly extractive protocols may reveal a precious strategy for rethinking the management of such wastes, in line with the fundamentals of “circular economy”.
