detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Antioxidant activity of Lactobacillus plantarum strains isolated from traditional Chinese fermented foods.
Eleven Lactobacillus plantarum strains isolated from traditional Chinese fermented foods were investigated for their in vitro scavenging activity against hydroxyl and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals, and their resistance to hydrogen peroxide. L. plantarum C88 at a dose of 10(10) CFU/ml showed the highest hydroxyl radical and DPPH scavenging activities, with inhibition rates o...
متن کاملDetermination of Bacteriocin Genes and Antibacterial Activity of Lactobacillus Strains Isolated From Fecal Healthy Individuals
Lactobacillus species play an important role in gastrointestinal (GI) tract function, intestinal microbiota balance, and the immune system activity by exerting a strong activity against many intestinal pathogens. The aim of this study was to isolate Lactobacillus species from fecal samples, investigate their antimicrobial properties, and characterixe their bacteriocins encoding genes. 48 fecal ...
متن کاملAntioxidant Activity, Antiproliferation of Colon Cancer Cells, and Chemical Composition of Grape Pomace
Chardonnay and Tinta Cao grape pomaces were generated by the winemaking process. The pomaces were extracted with 50% acetone and tested for antioxidant capacities using the oxygen radical absorbance capacity (ORAC) assay, 50 EC , and ABTS •+ scavenging capacity tests. Cytotoxicity and antiproliferative activities against Caco-2 and HT-29 human colon cancer cell lines were also analyzed. The qua...
