“…The results of DPPH scavenging effect of LSE and LZE were higher than what was reported by Cheung et al (7). DPPH assay is a widely used method to evaluate antioxidant activities in a relatively short time compared to other methods (21). It has the advantage of being unaffected by certain side reactions which is common in laboratory-generated free radicals such as the hydroxyl and superoxide anion (3).…”

Antioxidant and antimicrobial potentials of extracts obtained from four wild mushrooms, Termitomyces clypeatus (TCE), Termitomyces robustus (TRE), Lentinus subnudus (LSE) and Lenzites species (LZE) collected in Nigeria were investigated. LSE and LZE displayed good scavenging activity against 2, 2-Diphenyl-1-Picrylhydrazyl (DPPH) and ferrous ion radicals at concentration of 2 mg/mL. However, TRE and TCE exhibited better superoxide anion scavenging effect at 2 mg/mL. All extracts (TCE, TRE, LSE and LZE) had comparable scavenging effect on hydroxyl radicals as butylated Hydroxytoluene (BHT) used as control. Moreover, extracts from the wild mushrooms were able to inhibit the growth of all indicator organisms at concentrations between 12.5 mg/mL to 100 mg/mL. LSE and LZE, however, showed better antimicrobial effect on the indicator organisms. The results suggest that extracts obtained from the four wild mushrooms may serve as sources of new bioactive compounds with effective antioxidant and antimicrobial activity.

“…The cell lines were cultured in Dulbecco's Modified Eagle's Medium or Roswell Park Memorial Institute Medium 1640 containing 10% (v/v) heat-inactivated fetal bovine serum, 100 units/mL penicillin, and 100 µg/ mL streptomycin (Invitrogen Life Technologies, Inc., Grand Island, NY, USA). Cells were maintained in a humidified have shown the biological activities and chemical quality of essential oils from these species (Tsai et al, 2007;Mokbel and Hashinaga, 2006;Kubo et al, 2005;Itoh et al, 2009a;2009b). The concentration of phytochemicals depends on many factors, such as the cultivar type, growing conditions, and country of origin.…”

Supercritical CO 2 extract from fruits of Citrus hassaku Hort ex Tanaka, Citrus iyo Hort. ex Tanaka, and Citrus grandis Osbeck, locally known as phalsak, yeagam, and dangyuja, respectively, in Korea, were analyzed by gas chromatography-mass spectrometry (GC-MS). In total, 70, 79, and 76 compounds were identified in fruits of phalsak, yeagam, and dangyuja respectively. (Z)-9-Octadecenoic acid was the major compound in phalsak, whereas limonene prevailed among the others. α-Terpineol, (E,E)-2,4-decadienal, hexadecanoic acid, pentacosane, stigmasterol, and γ-sitosterol were prominent in all species. Antiproliferative activity of the fruit extract was revealed through the colorimetric MTT (tetrazolium) assay against human glioblastoma U373MG, SNU-16 gastric cancer cells, HeLa cervix adenocarcinoma cells and AGS gastric adenocarcinoma cells. Although all tested fruit extracts exhibited antiproliferative effects toward cancer cells, different cell lines varied in their sensitivity to the same plant fruit extract.

“…DPPH free radical was widely used to investigate the scavenging activity of some natural compounds and the scavenging activity against DPPH free radical is a quick method to evaluate antioxidant activity [28]. When the DPPH free radical was scavenged by a proton-donating substance, such as an antioxidant, the absorbance at 517 nm was reduced [29].…”

The housefly is an important resource insect and the housefly larvae are ideal source of food additives. The housefly larvae protein hydrolysates were obtained by enzymatic hydrolysis by alcalase and neutral proteinase. Their antioxidant activities were investigated, including the superoxide and hydroxyl radicalscavenging activity, 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity, reducing power and metal chelating activity. The antioxidant activities of both hydrolysates increased with their increasing concentrations. The alcalase hydrolysate (AH) showed higher scavenging activities against hydroxyl radical and superoxide anion radical at low concentrations and higher metal-chelating activity than the neutral proteinase hydrolysate (NPH). The NPH exhibited higher scavenging activity against DPPH free radical and higher reducing power than the AH. Both hydrolysates showed more than 50% superoxide anion radical-scavenging activity at 10 μg/mL. These results indicate that both housefly larvae protein hydrolysates display high antioxidant activities and they could serve as potential natural antioxidant food additives.
