Китайский. ［目的］优选出痹痛贴剂的最佳乙醇回流工艺条件。［方法］在单因素试验基础上，选取乙醇浓度、提取时间、乙醇用量和提取次数4因素进行正交试验，对莪术等3味药材的乙醇回流工艺进行优选，以姜黄素含量和干膏得率为评价指标，采用HPLC法进行测定。［结果］最佳乙醇回流工艺为：80%乙醇10倍量提取3次，每次1 h。在此提取条件下，姜黄素含量达2.59 mg/g，干膏得率为6.80%。［结论］该工艺合理稳定，可为工业生产提供理论基础。_

Under the above conditions, the content of curcumin was 2.59 mg/g, dry extract yielding rate was 6.80%. ［Conclusion］ The process was reasonable and stable, which can offer the theoretical basis for industrial production._
