1、正交设计法优选六月青多糖胶囊提取工艺葛文漪，黄建春，陈兆霓，焦阳，张士军，黄仁彬*(广西医科大学药理学教研室，南宁530021)[摘要]目的：优选六月青多糖胶囊提取工艺的最佳条件。方法：选用L9(34)正交试验设计方法，分别对水煎煮及醇沉两个步骤进行优选，以多糖含量为水煎煮工艺评价指标；采用苯酚-浓硫酸法测定总多糖含量，以多糖含量和收率为醇沉工艺综合评价指标，确定最佳提取工艺参数。结果：六月青多糖胶囊最佳提取工艺为生药材加10倍量水，每次煎煮2h，煎煮3次。水提液过滤、合并、浓缩至含生药0.5g·mL-1，7倍量95%乙醇沉
2、淀12h，沉淀1次。结论：优选出的工艺条件,经验证其结果稳定、合理，可作为六月青多糖胶囊的最佳提取工艺。[关键词]六月青胶囊；正交试验；提取工艺；煎煮法；醇沉法OptimizationofExtractionTechnologyforLiuyueqingPolysaccharidesCapsulebyOrthogonalDesignGEWen-yi,HUANGJian-chun,CHENZhao-ni,JIAOYang,ZHANGShi-jun,,HUANGRen-bin(DepartmentofPharmacology,G
