4-O--D-Manopyranosyl-D-mannose, O--D-mannopyranosyl-(l4)-O--D-mannopyranosyl-(14)-D-mannose, and 0--D-mannopyranosyl-(14)-O--D-mannopyranosyl-(l4)-O--D-mannopyranosyl-(l4)-D-mannose have been isolated fron the products of the partial hydrolysis of ungeromannan-V, obtained fron the bulbs ofUngernia vvedneskyi, and have been identified. This set of oligosaccharides confirms the regular structure of the carbohydrate chain of ungeromannan-V, which consists of a linear sequence of -14-bound D-mannose residues.DeceasedTranslated from Khimiya Prirodnykh Soedineii, No. 4, pp. 434–436, July–August, 1981. 相似文献

Conclusions The structure of leontoside D-a hederagenin pentaoside-has been established. The O-glycosidic moiety of leontoside D is O--D-glucopyranosido-(1 4)-O--L-arabopyranose, and the O-acyl moiety is O--L-rhamnopyranosido-(1 4)-O--D-glucopyranosido-(1 6)-O--D-glucopyranose.Khimiya Prirodnykh Soedinenii, Vol. 4, No. 3, pp. 153–158, 1968 相似文献

The structure of the branched polysaccharide glucoarabinogalactan was investigated by periodate oxidation, methylation, and 13C NMR spectroscopy. The main chain consists of -16-bonded galactopyranoses. 12-Bonded D-glucopyranoses and 13-bonded D-galactopyranoses are located on the unreducing ends. There is a short side chain with -13-bonded L-arabinopyranoses. 相似文献

From a methanolic extract of the bulbs ofAllium turcomanicum Rgl. we have isolated a new furostanol glycoside, turoside C (I). An acid hydrolysate was found to contain the aglycone — neoagigenin (II) — and the sugars D-xylose, D-glucose, and D-galactose in a ratio of 1:4:1. The structure of the furostanol (I) has been established by methylation, enzymatic hydrolysis, and oxidative cleavage, and also by the oxidative cleavage of (II), as (25S)-5-furostan-2,3,6,22,26-pentaol 26-O--D-glucopyranoside 3-O-{[O--D-xylopyranosyl-(13)]-[O--D-glucopyranosyl-(12)-O--D-glucopyranosyl-(12)]-O--D-glucopyranosyl-(14)--D-galacto-pyranoside}.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
