A Water-Soluble Polysaccharide from the Fruit Bodies of Bulgaria inquinans (Fries) and Its Anti-Malarial Activity

A water-soluble polysaccharide (BIWS-4b) was purified from the fruit bodies of Bulgaria inquinans (Fries). It is composed of mannose (27.2%), glucose (15.5%) and galactose (57.3%). Its molecular weight was estimated to be 7.4 kDa (polydispersity index, Mw/Mn: 1.35). Structural analyses indicated that BIWS-4b mainly contains (1 → 6)-linked, (1 → 5)-linked and (1 → 5,6)-linked β-Galf units; (1 → ...

Structural Characterization of a Water-Soluble Polysaccharide from the Fruiting Bodies of Agaricus bisporus

An edible fungal polysaccharide termed as ABP was obtained by extraction with hot water, and followed successive chromatographic purification using DEAE-Sepharose Fast Flow column and Sephacryl S-300 High-Resolution column. A symmetrical peak was obtained on high-performance size-exclusion chromatography with an average molecular weight of 5.17 × 104 Da, which was named ABP, and its main compon...

Properties of rice cooked with commercial water-soluble soybean polysaccharides extracted under weakly acidic conditions from soybean cotyledons.

It has been found that commercial water-soluble soybean polysaccharides (SSPS) can make cooked rice and noodles non-sticky and prevent rice grains and noodles from adhering to each other. We studied in detail the phenomenon of rice cooked with SSPS. We assumed that the phenomenon resulted from the interaction between SSPS and starch during cooking, and studied the effects of SSPS on the gelatin...

Preparation of bioactive water-soluble pachyman hydrolyzed from sclerotial polysaccharides of Poria cocos by hydrolase

Water-soluble pachyman (WSP) was prepared by enzymic hydrolysis of pachyman extracted from Poria cocos sclerotium using a 0.5 mol l 1 NaOH solution at the optimized conditions of 55 1C, pH 4, 4% pachyman, 2 U ml 1 hydrolase, and a hydrolysis time of 6 h. Two WSP fractions, WSP-1 and WSP-2, were prepared using SephadexG-100 to separate WSP. Both fractions were of the b-(1-3)-D-dextran structure ...

Water-soluble constituents of Glehnia littoralis fruit.

From the water-soluble portion of the methanol extract of the fruit of Glehnia littoralis Fr. SCHMIDT ex MIQ. (Umbelliferae; "hamabofu" in Japanese), thirty compounds, including three new monoterpenoids and a new monoterpenoid glucoside, a new benzofuran glucoside, a new alkyl glucoside, and a new glucide, were obtained. Their structures were clarified by spectral investigation.
