Effect of five different stages of ripening on chemical compounds in medlar (Mespilus germanica L.).
The study of changes of nutritional value of fruit during the ripening process can help estimate the optimal date for fruit harvesting to achieve the best quality for direct consumption and further utilization. The aim of this study was to monitor the changes of chemical composition of medlar fruit (Mespilus germanica L.) measured at five various ripening stages including 134, 144, 154, 164 and...
Introduction: In traditional and modern medicine, active ingredients of medicinal plants have many applications in food, pharmaceutical, medical and industry. Antioxidants are compounds that prevent the oxidation process in the cell. Echium amoenum L. is a plant which grows in the mountainous regions of Mazandaran. This plant has different biological effects such as sedation, anti-inflammation,...
In a recent publication1 we reported on the isolation and identification of flavonoids and cinnamic acid derivatives from spinach chloroplast preparations. These cinnamic acid derivatives and flavonoids are obtained as low molecular fractions I and II from a water extract — called S^eth — from ether treated lyophilized chloroplasts, which is assumed to contain functional components of the photo...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
Evaluation of Hypoglycemic and Genotoxic Effect of Polyphenolic Bark Extract from Quercus sideroxyla
Quercus sideroxyla is a wood species whose bark has phenolic compound and should be considered to be bioactive; the hypoglycemic and genotoxic properties of Q. sideroxyla bark were evaluated in this study. Total phenolic compound was determined in crude extract (CE) and organic extract (OE). The OE has the highest amount of phenols (724.1 ± 12.0 GAE/g). Besides, both CE and OE demonstrated effe...
By-products obtained from winemaking processes still contain large amounts of phenolic compounds, especially phenolic acids, flavanols, flavonols, stilbenes, and flavonoids. Enzymatic hydrolysis was used for determination and characterization of phenolic acids, flavanols, flavonols, and stilbenes. Characterization of the flavonoids was achieved using acid hydrolysis with 0.1% hydrochloric acid....
The extraction yields, active compounds and antioxidant properties of 50%-aqueous-ethanolic extracts of freeze-dried Echinacea purpurea flower with multi-steps and multi-batches extraction methods were assessed. In multi-steps extraction, the extraction yields of 1st, 2nd, and 3rd extracts were 21.52%, 9.33%, and 2.90%, and their total phenols contents were 182.08, 176.33, and 177.08 mg CAE/g, ...
abstract: the essential oil of plant material is the fraction isolated by means of several methods such as liquid carbon dioxide, microwaves and low or high pressure distillation employing boiling water or hot steam and is chemically defined as terpenoids namely monoterpene and the oxygenated form. since these compounds might be employed as flavour contributors due to their chemical nature, it ...
the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...
