Study on the extraction process of hongyao tablet by orthogonal design

Objective To optimize the extraction process of hongyao tablet. Methods Orthogonal test was employed for selecting the optimum of extraction process by the indexes of the contents of ginsenoside Rg1, ginsenoside Rb1, notoginsenoside R1 and total solid matters. Results Six volumn of 70% alcohol, extracting 3 times with an hour for each time was considered the optimum extraction process of hongyao tablet. Conclusion The considerable extraction rate active components in the drugs are achieved by applying the selected technics.
