“…Reflecting such wealth of organic acids and phenolic acids, the reducing power reflected by FRAP value for umezu samples showed high values, ranging from 162.9 g/L to 186.43 g/L Trolox equivalent, depending upon the species and origin areas. In accordance with our results, Debnath et al [24] revealed that the extract of Mume Fructus exhibited high scavenging activities on DPPH, ABTS, hydroxyl, and superoxide radicals with the IC 50 of 0.40, 0.36, 1.75, and 1.60 mg/ml, respectively. It was reported that the reducing power properties are generally associated with the presence of reductones, which have been shown to exert an antioxidant action by breaking the free radical chains by donating a hydrogen atom [25].…”

This paper investigated chemical composition and antioxidant activities of umezu, pickling liquid of Prunus mume, from different factories in South and East China. The organic acid and phenolic acid profiles were also analyzed. Results showed that umezu was rich in organic acids and extremely sour as P. mume fruit in addition to its high NaCl level (≥20%). Total acid in umezu was more than 43.78 g/L in which main organic acids were citric acid and malic acid. Umezu contained more than 250.54 mg GAE/L total phenolic in which dominant phenolic acids were hydroxycinnamic acid derivatives. Umezu exhibited powerful antioxidant activities in ORAC, ABTS, DPPH, and FRAP assays. Reducing sugar, phenolic compounds, and antioxidant activities of umezu were affected by sample origins and fruit cultivars. Given its rich flavor components and high antioxidant activity, umezu could serve as a new dietary supplement or a natural preservative in food industry.

“…Total flavonoid content was determined by using a colorimetric method with catechin as a standard, for which a calibration curve was obtained with solutions of 0.05 to 0.5 mg/mL of this compound ( y = 0.0125 x + 0.0139, R 2 = 0.9804), described by (Debnath et al . 2010) with some modifications.…”

Oxidative stress induced by free radicals is the main cause of many human diseases. Plant‐derived antioxidant supplements can counter oxidative damage in cells. The purposes of this study were to investigate the effects of water extracts from dried seeds of Benincasa hispida (B. hispida) on antioxidant activity and how this related to total contents of phenolics and flavonoids in vitro. The levels of phenolic and flavonoid compounds were 81.3 ± 1.4 µg gallic acid /g and 486.8 ± 4.1 µg catechin/g dry mass, respectively. B. hispida showed DPPH (2,2‐diphenyl‐picrylhydrazyl hydrate), ABTS (1, 2,2′‐azinobis‐[3‐ethylbenzothiazoline‐6‐sulfonic acid]) and hydroxyl radical scavenging activity in a dose‐dependent manner, with maximum inhibition of 79.8 ± 0.2%, 82.3 ± 1.9% and 95.5 ± 0.8%, respectively. Inhibition of linoleic acid oxidation and nitrite scavenging activity were maximum 73.2 ± 1.0% and 73.6 ± 1.3% at 6 days and 1‐h incubation time, respectively. Our data suggest that the dried seeds from B. hispida could be used as a source of natural antioxidants in the food industry. PRACTICAL APPLICATIONS Other evidence suggests that the consumption of wax gourd promotes health. This is because of several important bioactive compounds such as lipids, protein, carbohydrates, fiber, minerals and vitamins that have already been isolated from wax gourd. Wax gourd is effective against diabetes, dropsy, diseases related to liver, leucorrhea and fever. It can strengthen the function of bladder and small and large intestines. It is also good for the detoxication of minerals. The findings of this study can demonstrate the antioxidant activity of the water extracts from B. hispida dried seeds. The nitrite and free radical scavenging effects of the extract would be useful to improve human health.

The hepatoprotective activity of Haliotis discus hannai Ino extract (HDE) against lipopolysaccharide (LPS)‐induced liver damage was investigated in rats. LPS (5 mg/kg body weight) produced hepatic damage that was manifested by significant increases in the activities of marker enzymes (aspartate transaminase, alanine transaminase) and reduced antioxidant (superoxide dismutase, catalase, glutathione peroxidase, malondialdehyde) activities. These antioxidant activities were elevated by HDE administration to LPS‐treated rats. These results suggested that HDE extracts had a potential hepatoprotective effect in LPS‐induced liver damage without any acute toxicity. In addition, reducing power of the extracts and their ability to scavenge free radicals were evaluated by applying DPPH (1,1‐diphenyl‐2‐picrylhydrazyl) and ABTS [2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) diammonium salt]. This study demonstrates that these extracts have potential hepatoprotective activity which is mainly attributed to the antioxidant potential. Practical Applications Pacific abalone is an important marine food resource in many Asian countries. A number of experimental studies have demonstrated numerous health benefits of Pacific abalone. In South Korea, abalone has important economic significance as a food and as a functional food. In addition, numerous recent research studies have focused on the nutritional and pharmaceutical values of abalone.
