摘要: 为确定以花楸果实多糖的提取工艺,先用分光光度法测定超声提取的天山花楸不同部位多糖的含量,再设计正交试验筛选超声提取天山花楸果实多糖的最佳工艺条件。结果表明:天山花楸各部位中果实含糖量最高,为4.63%。最佳工艺条件为以95%乙醇溶液醇沉、料液比1:45(g/mL)、超声时间45min、超声功率240W,天山花楸果实中多糖含量可达到5.92%。其中,料液比是影响天山花楸多糖得率的显著性因素。

Abstract: The purpose of this study was to optimize the extraction of polysaccharides from the fruits of Sorbus tianschanica Rupr.. Polysaccharide contents of different parts of Sorbus tianschanica Rupr. including roots, stems, leaves and fruits were assayed spectrometrically, followed by optimizing conditions for the extraction of polysaccharides from the fruits of Sorbus tianschanica Rupr. by orthogonal array design method. The fruits of the plant showed the highest polysaccharide content (4.63%) among the four parts. The optimized extraction conditions were using distilled water as the extraction solvent at a material/liquid ratio of 1:45 for 45 min extraction with the assistance of 240 W ultrasonic treatment. Under these conditions, the highest extraction yield of polysaccharides from the fruits of Sorbus tianschanica Rupr. could reach 5.92%. Moreover, material/liquid ratio was found to be the most significant factor affecting polysaccharide extraction.
