Structural characterization of the water-extractable polysaccharides from Sophora subprostrata roots
The crude polysaccharide SSa, obtained from the roots of Sophora subprostrata by boiling-water extraction and ethanol precipitation, was fractionated by anion-exchange and gel permeation chromatography, giving four polysaccharide fractions termed SSa1, SSa2, SSa3, and SSa4. Their structural features were investigated by sugar analysis, methylation analysis, partial hydrolysis, and NMR spectrosc...

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولP.B. (2015) Mesorhizobium waimense sp. nov. isolated from Sophora longicarinata root nodules and Mesorhizobium cantuariense sp. nov. isolated from Sophora microphylla root
31 32 In total 14 strains of gram-negative, rod-shaped bacteria were isolated from Sophora 33 longicarinata and Sophora microphylla root nodules and authenticated as rhizobia on these 34 hosts. Based on the 16S rRNA gene phylogeny, they were shown to belong to the genus 35 Mesorhizobium, and the S. longicarinata strains were most closely related to Mesorhizobium 36 amorphae ACCC 19665 (99.8 – 9...
متن کاملDraft Genome Sequence of Bacillus litoralis C44, Isolated from Chinese Scholar Tree (Sophora japonica) Forest Soil
Bacillus litoralis C44 can hydrolyze rutin to produce isoquercetin by the enzyme α-l-rhamnosidase. We report here the genome sequence and annotation result of strain C44. The genomic information will serve as references to the physiology, genetics, and evolution of this species and further genetic engineering research in this species.
متن کاملInhibitory effects of kurarinol, kuraridinol, and trifolirhizin from Sophora flavescens on tyrosinase and melanin synthesis.
Previously, it was reported that some prenylated flavonoids contained in the dichloromethane fraction of the ethanolic extract of Sophora flavescens, such as kuraridin, sophoraflavanone G, kurarinone, and kushenol F, are tyrosinase inhibitors; however, based on the level of these inhibitors in the extract, its inhibitory effect on tyrosinase activity was higher than expected. This has led us to...
