6-prenylnaringenin (6pn) is a chiral prenylflavonoid found most prevalently in hops ( humulus lupulus ) and present in hops and hop products. it is an isomer of the potent phytoestrogen, 8-prenylnaringenin. an enantiospecific method for quantitation 6pn by lc-esi-ms has been developed. baseline enantiomeric resolution of 6pn was attained on a chiralpak ® ad-rh column with an isocratic mobile ph...

Silvicultural operation need to notice the species diversity. To this study Gomarlang district in marivan region, northern zagros forest was selected. In this study 30 circle sample plots (500 m2) were collected by random method. In every sample plot the kind of species and number of trees and shrub were recorded. In the sample plots the micro plots of 5 m by 5 m (i.e. area of 25 m2) were desig...

this experiment was carried out to investigate the effect of plant density on growth and seed yield of wheat (kodasht cultivar) under saline soils and rainfed condition inanbarolum region of golestan province in 2008-09. an experiment was conducted in three fields with different salinities (6.73, 9.34 and 11.63 ds m-1) based on randomized complete blocks design. treatments were four plant densi...

introduction salinity is a major abiotic stress that affects approximately 7% of the world’s total land area. cotton (gossypium barbadense l.) is considered as one of the most important cash crops which is widely used for agricultural and industrial purposes. although, cotton is classified as one of the most salt-tolerant major crops but its growth and development are adversely affected by soil...

Silvicultural operation need to notice the plant species diversity in forest. To this study Gomarlang district in marivan region, northern zagros forest was selected. Selected 100 ha area because have similar physiography condition (north aspect and 1650 to 1800 m s.a.l. In study area 100 micro plots of 5m by 5 m (25 m2) including the species and the numbers of this species randomize...

melissa officinalis l. is a medicinal plant with a large variety of pharmacological effects and traditional applications. this study aimed to evaluate the protective and antioxidant activities of the extract of m. officinalis aerial parts on human umbilical vein endothelial cells (huvecs) under oxidative stress induced by h 2 o 2 . cells were incubated with h 2 o 2 (0.5 mm, 2 h) after pretreatm...

The effects of Meloidogyne incognita race 3 and M. arenaria race 1 on growth of kenaf cv. Everglades 41 was determined under greenhouse conditions. Seedlings of kenaf were inoculated with initial population densities (Pi) of 0, 625, 1,250, 2,500, 5,000, and 10,000 eggs/plant and placed on greenhouse benches in a randomized complete block design. Plant growth and nematode reproduction were asses...
