Abstract:
Objective:To optimize the extraction process of Guilong cataplasm .Methods:The yield of volatile oil was used as the index to optimize the volatile oil extraction technology by single factor tests. The yield of dry extract and the content of aconitine were used as the indices to optimize the water extraction technology by single factor tests and orthogonal test .Results:The optimal extraction conditions of volatile oil were as follows:the soaking time was 1h with 8-fold volume of water , and the extraction time was 6 hours.The optimal water extraction conditions were as follows:using 8-fold volume of water extracted for 3 times with 1 h for each time .Conclu-sion:The extraction process is simple , reasonable and reproducible ,which is suitable for the next research of Guilong cataplasm .
