“…Given that genotype x environment interactions (Gitonga et al, 2022) and fertilization regimes (Olyaie Torshiz et al, 2020) have the potential to affect the levels of polyphenolic compounds expressed in plants, further exploration could reveal cost‐effective cultural means of enhancing their concentration in developing nuts. Polyphenols are powerful antioxidants with many health benefits (Wojdylo et al, 2022), so increasing their concentration in pistachio nuts would also enhance their value for human consumption. Finally, the breeding and development of new pistachio cultivars should consider increased levels of polyphenols in kernels as desirable traits with the dual benefits of enhanced resistance to E. ceratoniae and improved nutritional properties.…”

The carob moth, Ectomyelois (=Apomyelois) ceratoniae (Zeller) (Lepidoptera: Pyralidae), also known as the locust bean moth, is a cosmopolitan pest of high-value fruit and nut crops, including carob, pomegranate, date, citrus and almond (Abedi et al., 2020;Hosseini et al., 2017;Nay, 2006). In Iran, adult moths typically emerge in early May and oviposit on pomegranate, a preferred host, where they may complete several generations before attacking pistachio (Mehrnejad, 2020). On pomegranate, eggs are laid in

Phytochemicals and Biological Activities of Walnut Septum: A Systematic Review

2023

View full text Add to dashboard Cite

In the last few decades, scientific evidence has stressed the importance of plants in the prevention and/or supportive treatment of a plethora of diseases, many of them chronic, age-associated disorders. Juglans regia L. is a traditional plant that has been integrated into traditional medicine since ancient times. Due to the presence of biologically active compounds, walnut was used in the treatment of various maladies. Recently, investigations have focused on the walnut by-products and waste products, with research on their valuable constituents and active properties. Among these secondary products, walnut septum was analyzed in several studies, its phytochemical profile described, and some of the biological activities examined. However, compared to other walnut by-products, no comprehensive review to gather all the pertinent scientific knowledge was found in the literature. Therefore, the aim of this study was to critically assess the information furnished by peer-reviewed articles regarding the walnut septum chemical composition and the related biological activities, including antioxidant activities, anti-inflammatory effects, antimicrobial properties, antidiabetic activities, anti-tumor properties, and anti-aging potential. In conclusion, as these preclinical studies showed that walnut septum metabolites were responsible for a wide range of preventive and therapeutic uses, further research should confirm the beneficial outcomes in clinical trials.

“…Nuts, regarded as pivotal elements within healthful diets, are not only a source of vital nutrients including proteins, fats and minerals but also a rich reservoir of small molecule phytochemicals such as polyphenols, flavonoids and alkaloids (Ros, 2010; Alasalvar et al ., 2020; Wojdyło et al ., 2022). Some studies have suggested that consuming nuts can have a positive impact on blood glucose levels, largely attributed to their phytochemical content, which may reduce carbohydrate digestion and absorption, thereby moderating spikes in blood glucose (Tindall et al ., 2019; Loizzo et al ., 2021).…”

SummaryInhibition of α‐glucosidases is recognised as an effective approach towards managing postprandial hyperglycaemia. This study aimed to identify a specific compound in Carya cathayensis Sarg. kernels (CCSKs) exhibiting strong inhibitory activities against α‐glucosidase and elucidate the inhibitory kinetic mechanism. Employing a bioassay‐guided approach, an α‐glucosidase inhibitor was isolated from CCSKs through sequential chromatography protocol involving AB‐8 macroporous adsorptive resin, Sephadex LH‐20 and C18‐reversed phase silica gel. The resulting inhibitor was a novel tannin compound, identified as rugosin C ethyl ester. Rugosin C ethyl ester displayed superior inhibitory activity (IC50 of 2.60 μg/mL) compared to acarbose (IC50 of 105.95 μg/mL). The kinetic analysis indicated that rugosin C ethyl ester had a mixed‐type reversible inhibition against α‐glucosidase. The inhibition constants (Ki and Kis) were determined to be 3.119 and 0.856 μg/mL, respectively. The findings indicated that rugosin C ethyl ester might serve as a promising functional ingredient in low‐glycemic index foods.
