The effect of heat treatment on the antioxidant activity extracts from Citrus unshiu peels was evaluated. (CP) (5 g) were placed in Pyrex Petri dishes (8.0 cm diameter) and heat-treated at 50, 100, or 150 °C for 10, 20, 30, 40, 60 min an electric muffle furnace. After treatment, 70% ethanol extract (EE) water (WE) (0.1 g/10 mL) CP prepared, total phenol contents (TPC), radical scavenging (RSA), reducing power determined. activities increased as heating temperature increased. For example,...
After far-infrared (FIR) radiation onto rice hull, a methanolic extract was prepared for the determination of antioxidant ability. 30 min FIR treatment, radical scavenging activity and total phenol contents hull extracts increased from 47.74 to 79.63% 0.12 0.19 mM, respectively, compared control. Inhibition lipid peroxidation in also 41.07 47.96%. According GC-MS analysis, more phenolic compounds (p-coumaric acid, 3-vinyl-1-oxybenzene, p-hydroxybenzaldehyde, vanillin, p-hydroxybenzoic...
The effect of cholesterol in the liposome bilayer on stability incorporated retinol was studied. Retinol into liposomes containing soybean phosphatidylcholine (PC) and (CH) at various ratios, were prepared as multilamellar vesicles by dehydration-rehydration method. readily a ratio 0.01:1 (w/w) retinol:lipid, with over 94.52% being all conditions incorporation efficiency increased slightly increasing CH content pH hydration buffer. Average particle size increased, mean sizes 5, 7, 9 30.27,...
After preparing 70% ethanol (EE) and water extracts (WE) from different parts (calyx, leaf, peel, pulp, stem) of eggplant, antioxidant activity the was evaluated. Total phenolic contents EE WE were highest in peel (55.19 mg/g) calyx (121.07 extracts, respectively. flavanol leaf (8.00 (5.61 The extract showed anthocyanins content (138.05 mg %) followed by (135.94 %), stem (110.38 (97.29 pulp (2.29 extracts. In both WE, relatively higher DPPH radical scavenging reducing power. remarkable high...
This study was conducted to determine the antioxidant activities and antigenotoxic effects of acetone, ethanol, methanol water extracts from four different parts (calyx, seed, peel flesh) persimmon fruits. Antioxidant were evaluated by DPPH (1,1-diphenyl-2-picryllhydrazyl) radical scavenging activity (RSA), ABTS (2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammononium salt) RSA reducing power (RP). Seed calyx showed significantly (p < 0.05) higher phenolic contents than flesh...
The cytotoxic and antitumor activity of methanolic extract rice hulls (MERH) were evaluated by the MTT-dye reduction assay against human colon cancer cells colonic aberrant crypt foci (ACF) in 1,2-dimethylhydrazine (DMH)-injected F344 male rats, respectively. MERH was found to be highly cytotoxic, with IC50 values 0.5 μg/mL vitro. Forty weeks supplementation (50 mg/kg body weight/day) reduced pre-neoplastic ACF formation 35% (p < 0.01). An active compound, momilactone B, isolated from silica...
Abstract Subcritical water (SCW) extraction of citrus pomaces (CPs) was carried out, and antioxidant activity nutraceutical compound levels the SCW extracts were evaluated in detail. At first, CP samples subjected to under various conditions focusing on temperature time. Consequently, highest total phenol contents, radical scavenging activity, reducing power found when at 200°C 1.4 MPa for 60 min. Furthermore, amounts three kinds polymethoxylated flavones (sinensetin, nobiletin, tangeretin)...
This study investigated the antihypertensive effects of an antioxidant peptide, Leu-Trp-His-Thr-His (LWHTH), purified from Styela clava peptic hydrolysate, to assess bioactivity peptide and verify value S. as a health-promoting food. Also, presented structural evidence for LWHTH. The inhibitory effect LWHTH on angiotensin I-converting enzyme (ACE) was assessed using reaction methods simulation in computational space. inhibited ACE with IC50 16.42 ± 0.45 μM. structure stable, its retained...
The processed green tea leaves were irradiated by far-infrared (FIR) at eight temperatures (80, 90, 100, 110, 120, 130, 140, and 150 °C) for 10 min. After FIR irradiation, teas prepared soaking the in boiling water, physicochemical characteristics of determined. irradiation 90 °C increased total phenol contents from 244.7 to 368.5 mg/g flavanol 122.0 178.7 mg/g, compared with non-irradiated control. also significantly affected amounts epigallocatechin gallate. Nitrite scavenging activity...
Summary The antioxidant properties of methanolic extracts from the fruit Prunus mume were determined in chicken breast meat systems. When P. extract (PM) was added to meat, 2‐thiobarbituric acid‐reactive substances (TBARS) value at day 3 decreased by about 45% control. PM did not affect colour compared with amounts volatile aldehydes and hydrocarbons significantly addition PM. Especially, hexanal most predominant compound control taking up almost more than 50% total volatiles reduced amount...
To determine the effect of far-infrared (FIR) irradiation on antioxidant activities sesame meal, half seeds were FIR-irradiated and then oil was extracted from seeds. The resulting defatted meal (DSM) with methanol, methanolic extract determined. FIR for 30 min increased total phenol content 34.0 to 59.0 μM radical scavenging activity DSM extracts 26.40 68.76%. induction time lipid oxidation added also retarded 0.82 0.96 h. According gas chromatography−mass spectrometry analysis, several low...
