Cucurbitaceae is one of the most economically important plant families, and includes some worldwide cultivated species like cucumber, melons, and squashes, and some regionally cultivated and feral species that contribute to the human diet. For centuries, cucurbits have been appreciated because of their nutritional value and, in traditional medicine, because of their ability to alleviate certain ailments. Several studies have demonstrated the remarkable contents of valuable compounds in cucurbits, including antioxidants such as polyphenols, flavonoids, and carotenoids, but also tannins and terpenoids, which are abundant. This antioxidant power is beneficial for human health, but also in facing plant diseases and abiotic stresses. This review brings together data on the antioxidant properties of cucurbit species, addressing the genetic and pre- and postharvest factors that regulate the antioxidant content in different plant organs. Environmental conditions, management, storage, and pre- and postharvest treatments influencing the biosynthesis and activity of antioxidants, together with the biodiversity of this family, are determinant in improving the antioxidant potential of this group of species. Plant breeding, as well as the development of innovative biotechnological approaches, is also leading to new possibilities for exploiting cucurbits as functional products.

Schizophyllum commune Fr., a native mushroom of Thailand, has a high nutritional value and is classified as a mushroom with medicinal properties that can neutralize the growth of many cancer cells. This research aimed to study the effect of S. commune strains and the extraction methods on the quantity and properties of β-glucan. The five S. commune Fr. strains used in this research consisted of Chanthaburi, 85-022, 85-023, 85-031, and 85- 043. There were two different β-glucan extraction methods employed: hot water (M1) and hot alkali extraction (M2), which were compared with the control (native-MR). The results indicated that the Chanthaburi strain has the highest β-glucan content 49.20±0.35% (w/w), and high potential antioxidant activity (79.14±0.77 DPPH% and 50.92±0.48 ABTS%) (p < 0.05). The extraction methods did not affect the yield of β-glucan, except the antioxidant properties and chemical structure of the extract substance. The extract substance from M2 has significantly the highest potential antioxidant activity (80.22±0.51). A mushroom juice drink in cans was developed using 1-day-old MR and adjusted pH of more than 7, which can increase the antioxidant properties of the product.

In Iran, wheat straw which is produced in huge amounts has been used in animal feed. However, the use of straw as animal feed is limited by its low nutritional value and its low nitrogen content. Various chemical delignification methods to improve the digestibility of straw have extensively investigated (Sundstol and Owen, 1984). Biological methods of treating straw using fungi such as white-rot-fungi have also been reported (Zadrazil, 1984). The solid state fermentation (SSF) of wheat straw with white-rot fungi is a complex process which is influenced by factors such as the species of fungus, substrate, temperature and moisture (Zadrazil, 1984). The objective of this study was to investigate the effect of pre-treating the straw with urea and incubation with two species of Pleurotus fungi on the chemical composition and digestibility of wheat straw.

Beer, the most popular beverage containing hops, is also frequently consumed by cancer patients. Moreover, non-alcoholic beer, owing to its nutritional value and high content of biological active compounds, is sometimes recommended to patients by oncologists. However, the potential benefits and negatives have to date not been sufficiently evaluated. The present study was designed to examine the effects of four main hop-derived prenylflavonoids on the viability, reactive oxygen species (ROS) formation, activity of caspases, and efficiency of the chemotherapeutics 5-fluorouracil (5-FU), oxaliplatin (OxPt) and irinotecan (IRI) in colorectal cancer cell lines SW480, SW620 and CaCo-2. All the prenylflavonoids exerted substantial antiproliferative effects in all cell lines, with xanthohumol being the most effective (IC50 ranging from 3.6 to 7.3 µM). Isoxanthohumol increased ROS formation and the activity of caspases-3/7, but 6-prenylnaringenin and 8-prenylnaringenin exerted antioxidant properties. As 6-prenylnaringenin acted synergistically with IRI, its potential in combination therapy deserves further study. However, other prenylflavonoids acted antagonistically with all chemotherapeutics at least in one cell line. Therefore, consumption of beer during chemotherapy with 5-FU, OxPt and IRI should be avoided, as the prenylflavonoids in beer could decrease the efficacy of the treatment.

Abstract Objectives To study the nutritional value of cocoa shell, analyzing the chemical composition and functional properties as antioxidant, hypoglycemic and hypocholesterolemic effects, as well as validate the safety of cocoa shell as a sustainable food ingredient. Methods Proximate composition was determined following the AOAC methods. Soluble and insoluble fractions of dietary fiber (DF) were determined using enzymatic-gravimetric and chemical methods. The phenolic profile was analyzed by UPLC-MS/MS and antioxidant properties were tested using ABTS. Furthermore, physicochemical, hypoglycemic, and hypocholesterolemic properties were assessed in vitro. Acute and subchronic oral toxicity experiments were performed following OECD Guidelines 452 and 408 (5 male and 5 female C57BL/6 mice per group, vehicle/cocoa shell) to assess the food safety of cocoa shell flours. Results Cocoa shell was composed of carbohydrates (62%), proteins (16%), and fat (2%). DF represents 59%, being the insoluble dietary fiber (IDF) the main fraction (82%). IDF fraction was constituted by lignin (58%) and polysaccharides (42%); cellulose was inferred as the main polysaccharide of IDF, followed by hemicelluloses (arabinans and galactans). High content of phenolic compounds (33.7 mg/g) was shown, being a significant phenolic fraction (51%) bound to DF, which confers cocoa shell its antioxidant potential (73.1 mg Trolox eq/g). The main phenolics were protocatechuic acid, (−)-epicatechin, and (+)-catechin. Cocoa shell exhibited adequate water and oil holding properties to be included in food matrices. During in vitro digestion, starch hydrolysis and dialyzed glucose diminished (34 and 13%, respectively) due to α-amylase inhibition (18%) and glucose adsorption (31%). Cocoa shell also inhibited cholesterol and bile salts absorption (72 and 70%, respectively). The intake of acute (2000 mg/kg) and subcronical (1000 mg/kg) doses of the ingredient did not cause significant lesions in selected isolated vital organs (liver, spleen, and kidney) nor changes in histological parameters, ensuring the safety of this sustainable food ingredient. Conclusions Results validate the use of cocoa shell as an antioxidant dietary fiber ingredient, being a safe potential candidate to be incorporated in the development of foods for specific health uses.

Acetone Extracts

Acetone extracts from eggplant (Solanum melongena L.) and violet pepper (Capsicum annuum L.) peels both belonging to the Solanaceae plant family were characterized with respect to their anthocyanin profiles, colour qualities and antioxidant capacities. According to HPLC-DAD-MS3 analyses the major anthocyanin in eggplant was delphinidin-3-rutinoside, while the predominant pigment in violet pepper was assigned to delphinidin-3-transcoumaroylrutinoside- 5-glucoside. Since virtually all anthocyanins were delphinidin-based, the effect of acylation and glycosylation patterns on colour stability and antioxidant capacity could be assessed. Application of two in vitro-assays for antioxidant capacity assessment revealed that eggplant generally exhibited higher values compared to violet pepper which was ascribed to 3,5-diglycosylated structures predominating in the latter. The higher extent of acylation in violet pepper was reflected by a more purplish colour shade of the extracts, but did not translate into a higher stability against fading which again was attributed to additional glycosyl substitution at C5. These findings support the relevance of structurerelated activities of anthocyanins both for understanding food colour and their particular nutritional value.
