Optimization of Extracting Process for Weiningsu Capsules by Orthogonal Test / 中药新药与临床药理

Objective To optimize the extracting process for Weiningsu Capsule.Methods With dry extract rate and naringin content as the inspection indicators,orthogonal test was used to investigate the influence of four extracting factors (water volume,extracting time,times of extracting and soak time of herbal) on the extracting process.Results The optimum extracting process was A3B2C2D3,i.e.the water volume being 10 times of the weight of medicinal material,extraction for two times and 1.5 hours each time,and soaking for 1.5 hours.Conclusion Optimization of extracting process for Weiningsu Capsule by orthogonal test is a simple,quick and accurate method.
