A pectic fraction, accounting for about 0.3% of the total cell wall polysaccharide, was derived from the hot water extract of an insoluble fraction of the buffer-homogenate of Zea shoots. The pectic polysaccharide fraction was characterized by fragmentation analysis after hydrolysis with acid and Erwinia carotovora pectate lyase. The results suggest that the fraction consists of mostly a linear...

a water soluble polysaccharide, hb-1, with a molecular weight of 23,930, was isolated from radix ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. its sugar composition was determined by glc as glc, ara, and gal in a molar ration of 16.071: 2.722: 1. and the absolute configuration of glc was identified as ...

in some regions of isfahan, although there is no soil and water salinity limitations, quality of sugar beet root is very low because of using high amount of irrigation water. a study was conducted to determine the relation between low irrigation and quality and quantity of sugar beet. in this study, a line source irrigation system for six water use treatments (from 10770 to 8554 m3/hec) was use...

Eighteen Pediococcus strains were screened for their potential as silage inoculants. Pediococcus acidilactici G24 was found to be the most suitable, exhibiting a short lag phase on both glucose and fructose, a rapid rate of acid production, a high sugar-to-lactate conversion efficiency, no detectable breakdown of proteins or lactic acid, and the ability to grow within a broad range of pH and te...

due to the scarcity of water resources, the need for sustainable development of drip irrigation tape is essential in iran. a number of drip irrigation tape systems used in sugar beet fields of isfahan and chahar mahal va bakhtiari provinces were evaluated and were compared with furrow irrigation methods in two consecutive years. the actual water use efficiency (wuesy, wuewsy) in lower quarter, ...

lution property of poorly water soluble drugs. In general, solid dispersion is prepared with water soluble polymer, such as polyethylene glycol (PEG) or polyvinylpyrrolidone (PVP) as carrier, to disperse the drug molecules in the polymer matrix. Recently, the porous materials were also used as a carrier to disperse the drug molecules in the pores. We have already reported that the solid dispers...

The seeds of Acacia colei (Maslin and Thomson) and A. tumida (F. Muell ex Benth.) are traditional foods of Australian Aboriginal people. Chemical analysis was carried out on seeds of A. colei trees growing in Maradi district, Niger Republic and A. tumida from a natural stand near Kunanurra in north western Australia. Crude protein (N 6.25) ranged from 23.4% for whole A. colei seed to 30.6% for ...

Six hemicellulosic samples were isolated from cell wall material of dewaxed sweet sorghum (Sorghum bicolor (L.) Moench) leaves by sequential extractions with distilled water, alkali, and organic alkali solvent. The samples were treated with water, 1% NaOH, and 60% ethanol. The organic alkali samples were treated with 1%, 3%, 5%, and 8% NaOH, which yielded 8.3%, 5.4%, 1.0%, 5.6%, 2.5%, and 4.9% ...

this study was conducted to determine the effects of the combined use of rain shelters (rs) and deficit irrigation (di) on tomato yield and quality characteristics. two experiments with different treatments were conducted in the southern china during the growing season in 2011 and 2012. the crops were irrigated to field capacity once average soil water content at the 0-60 cm layer in the treatm...

purpose of this study was to investigate the effect of the presence of the water soluble polymers viz hpmc, pvp and peg 6000 on aqueous solubility and complexation abilities of felodipine with or without presence of β-cyclodextrin (βcd) and hpβcd by phase solubility studies. the data revealed the initial increase in drug solubility followed by plateau in the presence of relatively low polymer c...
