摘要
目的 优选梅花参中梅花参多糖的提取工艺。方法 采用正交设计L9( 34 ) ,以梅花参中葡萄糖醛酸的含量及其梅花参多糖的得率为工艺考察指标。结果 最佳工艺为A3B3C2 ,即药材加 4 0倍量 5 %KOH溶液 4 5℃搅拌提取 2h ,实验表明提取温度为最重要的影响因素。结论 该实验操作简单 ,方法稳定可靠 ,准确度高 。
OBJECTIVE To search for the best technique for extracting polysaccharide from Thelenota ananas . METHOD L 9(3 4) orthogonal design was adopted, with the content of glucuronic acid in thelenota ananas and the acquiring rate of polysaccharide from thelenota ananas as the observation indexes. RESULT The best technique was found to be A 3B 3C 2, i.e. 40 times of 5% KOH solution added to the medicinal materials stirred at 45℃ for two hours. Temperature was the most important factor in the process. CONCLUSION This technique is simple, stable, reliable and accurate, which provides evidence for the extraction of this kind of polysaccharides.
