Objective: To optimize alcohol extraction process of Shenqi Yiqi capsules. Method: With dry extract yield
contents of total ginsenosides and loganin as indexes
orthogonal design was carried out for optimizing extraction process by taking the concentration and amount of ethanol
extracting time and times as factors
optimum process was determined by multi-index test breakdown formula evaluation.Contents of total ginsenosides and loganin were determined by HPLC
mobile phase were consisted of acetonitrile(A)-water(B) in gradient elution(0-30 min
18.5%A;30-47 min
29%A;47-57 min
29%-40%A;57-65 min
40%-18.5%A) and acetonitrile-water (8:92)
detection wavelength were set at 203
240 nm
respectively. Result: Optimal alcohol extraction technology was as following:extracted twice with 6 times the amount of 80% ethanol for 2.0 h per time;extracting amounts of total ginsenosides and loganin were 167.28 mg and 319.51 mg
dry extract yield was 22.54%. Conclusion: This optimized extraction process is reasonable and scientific
which can provide a reference for improving clinical efficacy of Shenqi Yiqi capsules.
