Enzymatic proteolysis is helpful to release bioactive peptides encrypted in food proteins. The antioxidant capability of soy protein isolate (SPI) hydrolyzed with a novel protease preparation from Chryseobacterium sp. kr6 was investigated. The antioxidant capacity of the hydrolysates was evaluated using radical-scavenging and metal-chelating assays. Maximum values for scavenging of 2,2’-azino-b...

this study was carried out to investigate impacts of myrobalan rootstock and blackthorn interstem on fruit growth, physico-chemical features and bioactive compounds of two apricot cultivars (‘harcot’ and ‘roksana’) in 2010 and 2011. fruits of both cultivars on myrobalan and/or blackthorn grew with a classic double sigmoid curve from full bloom time to harvest. during growth and development peri...

conclusions increasing the cu nanoparticles in bioactive glass samples leads to the release of cu2+, which has a positive effect on the antibacterial mechanism, as well as decreasing the cultured staphylococcus colonies found on the bioglasses. therefore, it seems that the nanocomposite/bioglass of cuo is a promising option for aerobic bacterial inhibitor systems in common bone implant infectio...

Pterocarpans, a special kind of isoflavonoids possessing two contiguous benzofuran and benzopyran rings, have been reported as possessing several biological activities. In order to isolate and identify the active principles possibly responsible for the stronger activity of the EtOH extract from roots of Harpalyce brasiliana on the antimitotic assay using sea urchin egg development, a bioassay-g...

The aim of the study was to evaluate the biological activities and safety of commercial herbal concoctions manufactured in Ga Maja (Limpopo province). Microbial contamination was evaluated by spread-plating the concoctions on agar plates. The VITEK 2 instrument was used for identification of the pure cultures. Nutritional content of the concoctions was determined. Thin layer chromatography was ...

A world health organization survey indicated that about 75-80% of the world’s populations rely on non conventional medicine, mainly of herbal source, in their primary health care. There has been an explosion of scientific information concerning plants, crude extracts and various substances from plants as medicinal agents during last 30-40 years. Nowadays adiantum venustum plant parts are common...

An array of 76 endophytic bacterial isolates obtained from different plant tissues including root, stem and fresh and wilted leaves of various plants in Punjab, Pakistan were investigated for their antagonistic ability to biofilm formers. The morphological, biochemical and physiological characterization and 16S rRNA gene sequence analysis of the selected endophytic isolates leads to the identif...

Four bioactive compounds have been isolated from the fungus Oidiodendron griseum UBOCC-A-114129 cultivated from deep subsurface sediment. They were structurally characterized using a combination of LC-MS/MS and NMR analyses as fuscin and its derivatives (dihydrofuscin, dihydrosecofuscin, and secofuscin) and identified as polyketides. Albeit those compounds were already obtained from terrestrial...

BACKGROUND The fibrous proteins of extracellular matrix (ECM) produced by dermal fibroblast contributes to the maintenance of connective tissue integrity. OBJECTIVE This study is carried out to identify the bioactive ingredient from natural products that enhances ECM production in dermal fibroblasts. METHODS Bioassay-directed fractionation was used to isolate the active ingredient from natu...

OBJECTIVE To investigate the butanol fraction of the water/acetone extract and isolate of the new flavonoids from Launeae arboescens. METHODS The compounds were isolated by liquid chromatographic methods and their structures were identified by using spectroscopic analysis. RESULTS THE ISOLATED COMPOUNDS WERE IDENTIFIED AS: 7-O-[α-rhamnopyranosyl 4',5,6-Trihydroxy flavone 1,4',5'-Di-Methoxy ...
