Abstract:
AIM:To seek a simple and reliable process for extracting effective components in Diedahuoxue film.METHODS: According to uniform design, five factors in extraction were optimized, i.e. ethanol concentration, reflux time, reflux times,ethanol volume and drug particle. The absorption value was taken as evaluating parameter in UV- spectrophotometry. RESULTS: The results showed that the best extracting conditions were 95% ethanol, ten times amount of ethanol, 0.2mm size of particle and reflux time of 1h with 4 repetitions.CONCLUSION:This process is simple and reliable.
