Antihyperglycemic and antihyperlipidemic effect of Uraria crinita water extract in diabetic mice induced by STZ and food
Uraria crinita (UC) is a traditional edible plant and has been used as herbal medicine for a long history in China. There is no report on its anti-diabetic activity. In the present study we evaluated anti-hyperglycemic and anti-hyperlipidemic effect of U. crinita water extract (UCWE) in diabetic mice. Type II diabetes was induced in mice by injection of streptozotocin (STZ) in combination with high fat...

Matrine: A novel inhibitor of growth and proliferation of lung adenocarcinoma cells
To investigate the inhibitory effects of matrine on lung cancer and explore the potential mechanism, we studied the in vitro anti-proliferation activity of matrine in human lung adenocarcinoma A549 cells. The effects of matrine on the growth and proliferation were evaluated, and the cell cycles and early cell apoptosis were examined after treatment with various concentrations of matrine for 48 and 72 h, respectively....

Flavonoids with free radical scavenging activity and nitric oxide inhibitory effect from the stem bark of Artocarpus gomezianus
A MeOH extract from the stem bark of Artocarpus gomezianus showed DPPH free radical scavenging activity. Bio-assay guided fractionation of this MeOH extract led to the isolation of four flavonoids, namely artonin E (1), cycloartobiloxanthone (2), artobiloxanthone (3) and (+)-catechin (4). These compounds were shown to possess recognizable DPPH free radical scavenging activity and appreciable inhibitory...

Contents and antibacterial activity of flavonoids extracted from leaves of Psidium guajava
Four antibacterial flavonoids (morin-3-O-lyxoside, morin-3-O-arabinoside, quercetin, and quercetin-3-O-arabinoside) were isolated from fresh and driedPsidium guajava leaves, and their concentrations were determined. Among them, quercetin and morin-3-O-arabinoside were the most and the least abundant, respectively. Studies on inhibitory effects of the flavonoids on spoilage and foodborne pathogenic bacteria revealed...

Crocus sativus on serum glucose, insulin and cholesterol levels in healthy male rats
Saffron and its constituents are reported to have a wide range of biological activities. To determine the hypoglycemic effect of hydromethanolic extract of saffron, which has rarely been dealt with in previous studies and hypolipidemic effect of saffron extract, we investigated the effects of hydromethanolic extract of saffron on healthy male rats. The present study also aimed at evaluating the effects of saffron...

Hamcho (Salicornia herbacea) with probiotics as alternative to antibiotic for broiler production
A study was conducted with 140 "Ross" 1-day old broilers having four treatments to know the potentiality of Salicornia herbacea (Hamcho) probiotics (SHP) and suitable level in replacing antibiotic. The groups were control (basal diet), antibiotic (basal diet + 0.05% OTC) and SHP 0.5% and 1.0% with basal diet. The birds were arranged in a completely randomized design having 5 replications with 7...

Analysis of chemical composition of Chrysanthemum indicum flowers by GC/MS and HPLC
Chrysanthemum indicum flower is a traditional Chinese medicine with strong aroma and many previous studies focused on its essential oil. GC/MS and HPLC were used to determine its volatiles, flavonoids and flavonoid glycosides. Sixty three volatiles were detected and the abundant volatiles included 2,6,6-trimethyl-bicyclo[3.1.1]hept-2-en-4-ol, 2-(2,4-hexadiynylidene)-1,6-dioxaspiro[4.4]non-3-ene, germacrene D,...
