Protective effect of free phenolics from Turcz. root on carbon tetrachloride-induced liver injury and .

Protective effect of free phenolics from Turcz. root (FPLR) on CCl-induced hepatotoxicity and was first evaluated. Oral administration of FPLR (100 mg/kg bw) to mice significantly reduced the CCl-induced elevation of serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, triacylglycerols, total cholesterol, and total bilirubin.

Phenolic composition, DNA damage protective activity and hepatoprotective effect of free phenolic extract from Sphallerocarpus gracilis seeds.

The phenolic composition of the free phenolic extract from Sphallerocarpus gracilis seeds was analyzed by HPLC-MS and predominant compounds were chlorogenic acid, di-caffeoylquinic acid glucoside and luteolin-7-O-glucoside. The free phenolic extract was evaluated for DNA damage protective activity induced by ROO and OH radicals and hepatoprotective effect in vivo and in vitro. Results revealed that the free phenolic extract exhibited significant protective activity against both ROO and OH radical-induced DNA damage and the phenolic extract exerted more potent inhibitory activity against OH radical-induced damage than against that induced by ROO radicals.

Main nutrients, phenolics, antioxidant activity, DNA damage protective effect and microstructure of Sphallerocarpus gracilis root at different harvest time.

Sphallerocarpus gracilis roots harvested at two different times (T1: 12-10-2009 and T2: 15-04-2010) were analysed for their main nutrients, phenolics, antioxidant activity, DNA damage protective effect and microstructure. Results revealed that higher amounts of starch were detected in T1 S. gracilis root, whereas higher levels of reducing sugar, protein, amino acids and phenolic compounds were determined in T2 S.

Dynamic changes in gamma-aminobutyric acid and glutamate decarboxylase activity in oats (Avena nuda L.) during steeping and germination.

Gamma-aminobutyric acid (GABA) is the principal inhibitory neurotransmitter in the central nervous system and provides beneficial effects for human and other animals health. To accumulate GABA, samples from two different naked oat cultivars, Baiyan II and Bayou I, were steeped and germinated in an incubator. The content of GABA and glutamic acid as well as the activity of the glutamate decarboxylase (GAD) in oats during steeping and germination were investigated with an amino acid automatic analyzer.

Changes in the main nutrients, phytochemicals, and antioxidant activity in yellow corn grain during maturation.

Immature corn grains are becoming increasingly popular as a snack/vegetable, facilitating human consumption in some countries. Of particular interest were their nutritional and functional properties. Therefore, plants at stages M1 (74 DAS), M2 (86 DAS), M3 (98 DAS), and maturity stage (116 DAS), where DAS refers to days after seeding, were investigated for changes of the nutrients, phytochemicals, and antioxidant activity in corn grains during maturation.

Dynamic changes in phenolic compounds and antioxidant activity in oats (Avena nuda L.) during steeping and germination.

Samples from naked oat were steeped and germinated under controlled conditions in an incubator. Changes of phenolic compounds and antioxidant activity were investigated in oats during steeping and germination. Results revealed that phenolic compounds and antioxidant activity of oats varied with the difference in steeping and germination stages.
