agaricus bisporus and agaricus bitorquis are among most favorite mushrooms of the world. mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. na, k and li contents were high, while cr, cu, pb, co, zn, mn and ni concentrations were low in both agaricus bisporus and agaricus bitorquis. proximate analysis showed th...

background: spermatozoa preservation is an approach to improve the fertility rate to pass on the valuable genetic material from sire to their offspring. during the last 20 years, reproductive biotechnologists have focused on the approaches that improve spermatozoa cryosurvival. one of the possible mechanisms is supplementation in semen extender. objectives: the aim of this study was to evaluate...

the effect of kaolin on fruit and oil of olive cv. `zard’ was evaluated in a commercial orchard in fasacity, fars province. mature olive trees cv. `zard’ were sprayed with 0, 3 and 6% kaolin after 60 days, 60and 90 days and 60, 90, 120 days after full bloom. results showed that kaolin concentration and sprayingtime had not significant effects on physicochemical parameters but they had significa...

nowadays the use of probiotic products especially yogurt, due to having wonderful and health properties, has become popular in the world. in this study, the effect of homogenization pressure (100, 150 and 200 bars) and stage (single and two) on the amount of lactic and acetic acids was investigated. yoghurts were manufactured from low-fat milk treated using high pressure homogenization at 100,1...

in this study,oil was extracted from the liver and visceral fat of patin (pangasianodon hypophthalmus) and refined. the yield of oil after refining was 49.98%. the major yield loss (34.20%) happened during the degumming procedure. fatty acids found in the crude and refined oil were c12:0, c14:0, c14:1, c16:0, c16:1, c18:0, c18:1, c18:2, c18:3, c18:4, c20:0, c20:1, c20:4, c20:5, and c22:6. the d...

The pine nuts, as the most expensive ones, are a source of healthy oil. Accordingly, the hypothesis was genetic differences of pine species (Pinus spp.) affect their nut oil content and fatty acid phytovariability. A completely randomized design experiment with three replicates was done in Isfahan Flower Garden, Iran, using four pine species of chir pine (Pinus longifolia<...

Commercially available amino acids mixtures have several advantages such as enhancing assimilation of fertilizer, facilitating uptake of water and nutrients and improving photosynthesis of plants. To investigate the response of gerbera (Gerbera jamesonni L.) flowers ‘Saltino’ to foliar application of a mixture of 19 essential amino acids (0.25, 0.50 and 0.75 mg L-1) and ammonium nitrate (200 mg...

Background: Organic acids refer to a family of compounds that are intermediates in a variety of metabolic pathways. Many organic acids are present in urine from clinically normal individuals. Elevated levels of urine organic acids cause to the organic acidurias, disorders in which some metabolic pathways in organic acid metabolism are blocked. The present work identified major and minor urinary...

Background & Aim: Hydroxycinnamic acids are one of the most important bioactive substances of Echinacea drugs. These compounds possess immuno-enhancing activity and thus, total hydroxycinnamic acids are mostly used as the main criterion for quality control of Echinacea purpurea and its drugs.  Hence, the quality control of Echinacea requires to develo...
