【摘要】以95%乙醇为溶剂,用超声波提取黄花三宝木中的总萜成分,考察药材的不同部位、提取方法、提取次数、不同溶剂以及浓度等因素对黄花三宝木总萜提取率的影响,并采用正交实验优化提取温度、提取时间、液料比和超声功率等因素的水平参数.黄花三宝木枝条部位中总萜的含量较高,其最佳工艺参数为:超声温度
60 ℃,液料比30∶1 mL/g,超声时间30 min,超声功率300 W,该工艺下,黄花三宝木中总萜成分提取率高,总萜得率为1.27%.该提取工艺设计合理,结果可信,重复性好,操作简单,方法可行,稳定性高,标准偏差均在2.5%以内.%Taking 95% ethanol as solvent,the total terpenoids in Trigonostemon lutescens was extracted by ultrasonic.The influence of the different parts of drug,extraction method,extraction times,different solvents and concentration on the yield of Trigonostemon lutescens was investigated,and the horizontal parameters of the extraction temperature,extraction time liquid/soild ratio and ultrasonic power were used by orthogonal test optimization.The optimal condition through orthogonal tests is 60 ℃ as extraction
time,30∶1 mL/g as liquid-material ratio,30 min as extraction time and 300 W as ultrasonic extraction power.Under the above conditions to extract the total terpenoids,the extraction ratio is high,the average extraction ratio
was 1.27%.The analysis method is simple and reliable with good repeatability,stability and recovery,the standard deviation is within 2.5%.【总页数】5页(P1553-1556,1560)
