A reliable source of increased intake of vitamins and biologically active substances are not only berries and fruits, but also herbs. This article is devoted to the analysis of plant samples for antioxidant activity. The objects of study were selected herbs and flowering woody plants of the Samara region: small-leaved linden color (Tilia cordata), medicinal sage (Salvia officinalis L.), medicinal clover (Melilоtus officinalis), currant leaf (Folium Ribes nigrum), wild strawberry (Fragum folium silvam), grapes (Vitis labrusca). Plant material collected in the phase of mass flowering. Aqueous alcoholic extracts (1 : 1 ratio) were obtained from the samples at 37 °C for 2 hours. Anti-radical activity was tested using the free radical DPPH (2,2-diphenyl-1-pilkrilgidrazil), restoring force the FRAP method (Ferric Reduction Antioxidant Power), antioxidant activity in the linoleic acid system and the content of phenols, flavonoids. Analyzing the results obtained in this work, we can conclude about the presence of antioxidant properties. The leader in anti-radical activity and regenerative power was a currant leaf, a high content of phenols has linden color, the maximum content of flavonoids was also recorded in a currant leaf.

Abstract Crop failures associated with asparagus replanting have been ascribed to a combination of microbiological and chemical influences. Extracts from asparagus roots and soil were examined to locate inhibitory chemicals. Analysis of root extract fractions in a seedling assay showed that phenolic and saponin components inhibited growth but the most inhibitory material was located in the amino acid/carbohydrate fraction. However, inhibitory asparagus soil extracts did not contain significant levels of active compounds (tryptophan, caffeic acid) identified from root extracts.

This study aimed to investigate and determine qualitative and quantitative content of free organic acids, including ascorbic acid (vitamin C) of Sanguisorba officinalis rhizomes, roots and herb using thin layer chromatography method. Citric, tartaric and succinic acids had been found in Sanguisorba officinalis herb, oxalic, tartaric, citric and benzoic acids in Sanguisorba officinalis rhizomes and roots.

A potential allelochemical was isolated and identified from methanol extracts of asparagus (Asparagus officinalis L.) fresh root tissue. Fractions were collected by cellulose column chromatography and tested for inhibition by an asparagus seed germination bioassay. The fraction showing the greatest inhibition contained caffeic acid, as identified by melting point, thin-layer chromatography, and infrared spectrum analysis. Seed germination bioassays and greenhouse pot tests showed depression of seedling emergence when asparagus seeds were exposed to various dosages of crude filtrate, a methanol extract from crude filtrate, and caffeic acid.

Recently a novel DNA virus (Torque Teno Virus (TTV) has been identified in Japan and shown to be associated with elevated aminotransferase s levels after transfusion. However the exact role of TTV in pathogenesis of liver disease is yet to be established. The purpose of this study was to determine the prevalence of TTV in thalassemic patients and its relationship with elevated alanine-aminotransfrase (ALT) and aspartateaminotransfrase (AST). This cross-sectional analysis study was conducted on 452 thallasemic patients. Serums were collected from all of the patients, first ALT and AST levels were determined. Then, after DNA extraction, TTV DNA was amplified and detected using semi-nested PCR, followed by gel electrophoresis. Demographic characteristics and clinical data were collected from each participant for statistical analysis. The findings showed that 160 of 452 (35.4%) samples had TTV DNA detected by PCR. From 160 TTV DNA positive, 98 (61.20%) were female and 62 (38.80%) of them were male (P=0.549). The mean ALT and AST values in TTV positive group were higher than in TTV negative group, and the difference was statistically significant (p<0.0001). The result showed that the prevalence of TTV in thalassemic patients in Jahrom is less than other studies in Iran and the mean ALT and AST values in TTV positive individuals were about 2 times more than in TTV negative individuals.
