目的:优选骨痛贴膏的乙醇渗漉提取工艺条件。方法:以欧前胡素提取量为考察指标,用高效液相色谱法测定欧前胡素含量,以乙醇浓度、乙醇用量、浸泡时间、渗漉速度为影响因素,选用L_9(3~4)表进行正交试验。结果:优选工艺为:药材用10倍量的90%乙醇浸泡12 h,以7 ml·min~(-1)·kg~(-1)速度渗漉提取。结论:优选工艺提取的欧前胡素含量较高。而浸膏量较低。
OBJECTIVE: To optimize the condition of ethanol percolation extraction of bone pain paste. Methods: With the extraction of imperatorin as index, the content of imperatorin was determined by high performance liquid chromatography (HPLC). The effects of ethanol concentration, ethanol dosage, soaking time and percolation rate were studied. Orthogonal test table. Results: The optimum conditions were as follows: the medicinal materials were soaked in 10 times the amount of 90% ethanol for 12 h and percolated with 7 ml · min -1 kg -1. CONCLUSION: Imperatorin extracted by the preferred process is high in content. The amount of extract is low.
