“…Indeed, the antioxidant abilities of PPPs were stronger than that of polysaccharides obtained from Hovenia dulcis [8], and were positively related to their contents of polyphenolics (Table 1 and Figure 3), which further confirmed that the bonded polyphenolics could be one of the main contributors to the antioxidant abilities of PPPs [19,40]. Indeed, some phenolic compounds in PPPs determined by UPLC-Q-TOF-MS possess obvious in vitro antioxidant activities, such as gallocatechin [41], kaempferol [42], myricetin [43], and quercetin [44]. Previous study has also revealed that the main mechanisms for the antioxidant activities of polyphenols might be the metals chelation, the H-atom transfer, and the electron transfer [45].…”

Seven extraction methods, including hot water extraction (HWE), pressurized water extraction (PWE), ultrasound-assisted extraction, microwave-assisted extraction, ultrasound-assisted enzymatic extraction, high-speed shearing homogenization extraction, and ultrasound-microwave-assisted extraction, were utilized to extract polyphenolic-protein-polysaccharide complexes (PPPs) from Hovenia dulcis. Next, their physicochemical properties and in vitro antioxidant activities, antiglycation effects, and inhibition activities on α-glucosidase and α-amylase were studied and compared. The findings from this study indicate that various extraction processes exhibit notable influences on the physicochemical properties and in vitro bioactivities of PPPs. Extraction yields, contents of polyphenolics and flavonoids, apparent viscosities, molecular weights, molar ratios of monosaccharide compositions, and ratios of amino acid compositions in PPPs varied in different extraction methods. Furthermore, 13 phenolic compounds in PPPs, including rutin, myricitrin, myricetin, quercetin, kaempferol, protocatechuic acid, gallocatechin, p-hydroxybenzoic acid, ampelopsin, quercetin-7,4′-diglucoside, dihydroquercetin, 5-methylmyricetin, and naringenin, were identified. The relatively strong in vitro antioxidant activities, antiglycation effects, and inhibition activities on α-glucosidase and α-amylase were determined in both PPP-W and PPP-P obtained by HWE and PWE, respectively. The high content of total polyphenolics may be one of the main contributors to their in vitro bioactivities. The findings have shown that the PWE method can be an appropriate method to prepare PPPs with strong bioactivities for application in the functional food industry.

“…22 However, as far as we know, food applications and the fatty acid composition of the seeds were poorly studied, with a single work recently published. 20 According to Rydlewski et al 20 the seeds are a rich source of PUFAs, and 53% of the total lipids (TL) correspond to LNA. Based on that, the seeds of the Japanese grape are also a potential new source of n-3 PUFAs.…”

In this study, the fatty acid (FA) composition of the Japanese grape (Hovenia dulcis) seed oil (JGSO) was firstly evaluated. It was found that the seed oil is rich in alpha-linolenic acid (LNA), containing approximately 425 mg LNA g -1 of total lipids. A fish diet supplemented with JGSO was prepared and supplied to Nile tilapia to investigate the FA composition of the fillets. For this, Nile tilapia were submitted to two feeding treatments: a control diet with 4.2% of soybean oil, and a diet supplemented with 4.2% of JGSO. The LNA, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) values increased significantly (406, 153 and 126%, respectively) with JGSO in the diet and with an increase in feeding time, while the nutritional quality indexes, n-6/n-3 ratio and index of thrombogenicity, decreased 2.8 and 1.4 times, respectively. Thus, the replacement JGSO in the diet raised the nutritional lipid quality in Nile tilapia.Keywords: fatty acids, omega-3, Oreochromis niloticus, supplementation, LNA IntroductionOmega-3 polyunsaturated fatty acids (n-3 PUFA), especially alpha-linolenic acid (LNA, 18:3n-3), eicosapentaenoic acid (EPA,, and docosahexaenoic acid (DHA,, have been extensively studied and said to be beneficial to human health. [1][2][3] A high ratio of dietary n-6/n-3 (omega-6/omega-3) has been reported around the world, reaching ratios between 15:1 and 20:1, while the recommended value is between 2:1 and 1:1. 4 This imbalance in the n-6/n-3 ratios is the result of an excess intake of omega-6 polyunsaturated fatty acids (n-6 PUFAs) from corn, soybean, and sunflower oils. Furthermore, a high intake of saturated fatty acids (SFA) such as myristic acid (14:0), palmitic acid (16:0), and stearic acid (18:0), may contribute to an increase in the indexes of atherogenicity (IA) and thrombogenicity (IT) 6 and to a reduction in the hypocholesterolemic/hypercholesterolemic fatty acid ratio (HH). 7Around the world, flaxseed, perilla, and chia are known sources of LNA, [8][9][10] while fish and microalgae oils rank among the most important sources of EPA and DHA. 11,12 The Japanese grape is originally from Japan, but has quickly expanded to other countries, such as India, Paraguay, Argentina, and Brazil, due to its easy adaptation to the soil and resistance to cold. 13 The Japanese grape are deciduous trees, growing to 10 to 15 m and reaching 20 to 40 cm in diameter of the trunk, commonly used for ornamental and reforestation purposes, and the wood for production of energy, paper and cellulose. The fruit is a small dry capsule from 6 to 7 mm in diameter containing 2 to 4 seeds, attached to a peduncle, which becomes thickened and fleshy when mature, which is also sweet and pleasant-tasting. The seeds are brown with a circular shape from 4 to 8 mm in diameter.14 The peduncles (pseudofruits) can be consumed in natura or in dehydrated form and are also used for alcoholic fermentation, to produce wine or vinegar. 15,16 According to Bampi et al. 13 the peduncles are rich in sugars and have a high content of dietary fi...

“…Free radical species in general is Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) (Wojcik et al 2010). Presence of free radicals is causes of degenerative diseases such as arthritis, atherosclerosis, cancer, diabetes, and parkinson's (Rydlewski et al 2017). Preventing and minimizing the impact of free radicals is needed antioxidants (Huang et al 2013).…”

Bangun-bangun (Coleus amboinicus Lour.) leaves is a plant that has various types of active compounds that can be utilized in various fields of health and food. The purpose of this research is to determine the components of the active compound contained in the sample when extract with methanol by maceration method and antioxidant activity test with DPPH method using a UV-Vis spectrophotometer. The value of antioxidant activity is determined by the amount of ability to inhibit 50% concentration of free radicals from DPPH. Phytochemical screening results of methanol extract active compounds contained alkaloids, tannins, flavonoids, terpenoids and steroids, as well as phenolic & polyphenols. The test activity of methanol extract of Coleus amboinicus leaves and ascorbic acid in the amount of 38.83 and 4.18 included in the very strong category as antioxidants. The extract of Coleus amboinicus leaves has lower activity compared to ascorbic acid and has the potential to be used as a natural antioxidant in preventing and minimizing the effects of free radicals.
