DPPH-scavenging antioxidant potential of in vitro regenerated tissues of Stevia rebaudiana,Citrus sinensis and Saccharum officinarum was carried out to evaluate and explore new potential sources for natural antioxidants. These species are used in every day life and produced valuable secondary metabolites that scavenge toxic free radicals. Toxic free radicals can cause different diseases in...

Characterization of the volatiles and active components in ethanol extracts of fruits of Litsea cubeba (Lour.) by gas chromatography-mass spectrometry (GC-MS) and gas chromatography- olfactometry (GC-O)

Currently extracts fruits of Litsea cubeba (Lour.) (FLC) is mainly used as natural remedies, perfumery ingredients and food additives. This study reports characterization of the extracts from FLC, which widely distributes in southern China, Japan, and other parts of southeast of Asia. The ethanol extracts of FLC were analyzed by gas chromatography-mass spectrometry (GC-MS), GC-flame ionization detection...

Pretreatment with astragaloside IV protects H9c2 cells against hydrogen peroxide-induced apoptosis by scavenging of reactive oxygen species and regulation of Bcl-2 and Bax expression

Astragaloside IV (ASI), a saponin isolated from Radix Astragali, has been found to have potent cardioprotective effects. This study was designed to investigate whether ASI prevents cardiomyocytes from hydrogen peroxide (H2O2)-induced apoptosis. H9c2 cells were pretreated with different concentrations of ASI (5, 10, 20 μg/ml) for 24 h and then exposed to 100 μM H2O2 for 24 h. The cell viability were...

Polyhydroxyalkanoates production via Bacillus plastic composite support (PCS) biofilm and date palm syrup

Polyhydroxyalkanoates (PHAs) are a group of biopolymers resembling plastic due to their physical characteristics. PHAs are known to have great structural variety and biodegradability which add to their importance in replacing synthetic plastics and making them future green materials. Such biopolymers gained worldwide attention. Most bacteria produce biopolymers as an intracellular carbon and energy compounds. Several...

Antioxidant, α-glucosidase inhibitory activities in vitro and alloxan-induced diabetic rats’ protective effect of Indigofera stachyodes Lindl. root

The antioxidant capacity of Indigofera stachyodes Lindl. root (ISR) extract had been determined by using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS and ferric reducing antioxidant power (FRAP) assay, and α-glucosidase inhibitory activity using 96-microplate-based method test in vitro. Extracts of EtOAC (ISREA) and n-BuOH (ISRBU) were...

Optimization of Jatropha curcas for total flavonoids by response surface methodology and antibacterial activity

Jatropha curcas is known as a member of the Euphorbiaceae plants. In this study, using rutin in determining indicators, the extraction technology of total flavonoids was optimized by the ultrasonic assisted method with response to surface methodology from Jatropha leaves, and the antibacterial effects of total flavonoids were studied. Results of the response surface method showed that under the extraction...

Effect of aqueous extract of Lycium barbarum on serum CK, CK-MB activities and myocardium injury in exhausted swimming rats

Studies were undertaken to evaluate the effects of aqueous extract of Lycium barbarum on serum creatine kinase (CK) and creatine kinase mass (CK-MB) activities in exhausted swimming rats. Forty Wistar rats were randomly assigned to five groups: normal control group (NC), exhausted swimming model control group (MC), low dose of LBE administration group (I), middle dose of LBE administration groups (II) and high...
