摘要: 本文以杏鲍菇下脚料为材料,比较了碎块、细粉和超细粉末三种粉碎程度对杏鲍菇粗多糖提取及其理化性质和刺激巨噬细胞活性的影响。结果表明,细粉和超细粉末体积平均粒径分别为83.548 μm和17.553 μm,其中超细粉末均匀性好。与碎块相比,两种处理都可以显著提高杏鲍菇粗多糖的得率,其得率分别是碎块的3.04倍和4.14倍,粗多糖中多糖和β-葡聚糖含量也明显提高。HPSEC-MALLS-VS-RI联用分析多糖分子量分布结果显示,三种处理所得粗多糖均主要含有3个组分,其中组分1和组分2分子量都在100万道尔顿以上,为高分子量组分,粉碎处理可以使粗多糖中高分子量组分所占比例增加,且粉碎后各组分的分子量大于碎块相应组分的分子量。单糖组成分析结果显示,不同粉碎程度所得多糖的单糖种类相同,但单糖组成摩尔比差异较大,葡萄糖所占摩尔比随粉碎程度增加明显增大。三种粉碎程度所得粗多糖均具有体外刺激巨噬细胞释放NO的活性,但总体上超细粉碎方式所得多糖的活性最高。

Abstract: The differences of physicochemical properties and macrophages-activation activity of crude polysaccharides extracted from Pleurotus eryngii leftover with different particle sizes were compared in this paper.The results revealed that average particle sizes of fine powder and ultrafine powder were 83.548 μm and 17.553 μm,respectively.Ultrafine powder showed well uniformity.Crude polysaccharide yields of fine powder and ultrafine powder of  P.eryngii leftover were 3.04 times and 4.14 times higher than that of fragments,respectively.Meanwhile,the contents of polysaccharides and β-glucan in crude polysaccharides also increased.The high performance size exclusion chromatography-multiple angle laser light scattering-viscostar-refractive index detector (HPSEC-MALLS-VS-RI) was adopted to determine the molecular weight and characteristics of these fractions.Analysis results indicated that all three crude polysaccharides mainly contained three fractions with different molecular weights.High molecular weight fractions (Fraction 1 and 2) with Mw higher than 1×106 Da possessed higher proportion in grinding powder compared with that in the fragments.Furthermore,the molecular weight of all fractions in crude poloysaccharides extracted from fine powder and ultrafine powder was higher than that of the corresponding fractions from fragments.Monosaccharide composition analysis indicated that all crude polysaccharides consisted of 5 monosaccharides with varied molar ratios.The molar ratio of glucose increased along with the increasing of degree of grinding.All samples exhibited activities on stimulating RAW 264.7 macrophages to release NO.

Key words: Pleurotus eryngii leftover;ultrafine powder, β-glucan;monosaccharide composition analysis;molecular weight distribution;macrophages-activation activity
