Objective: To optimize ultrasonic extraction technology of rosmarinic acid
salvianolic acid B
cryptotanshinone and tanshinone ⅡA from Salviae Miltiorrhizae Radix et Rhizoma. Method: With extraction amounts of four active components as indexes
uniform design was adopted to optimize extraction technology by taking ethanol concentration
solid-liquid ratio
extracting time as factors.HPLC was employed to determine contents of four active components with mobile phase of methanol-0.01% phosphoric acid solution(0-3 min
30%A;3-5 min
30%-40%A;5-13 min
40%A;13-20 min
40%-58%A;20-22 min
58%-75%A;22-24 min
75%A;24-50 min
75%-85%A) for gradient elution and detection wavelengths at 286 nm(rosmarinic acid and salvianolic acid B) and 268 nm(cryptotanshinone and tanshinone ⅡA). Result: Optimum extraction conditions were as follows:ethanol concentration of 75%
liquid-solid ratio of 200 mL·g-1
extraction time 10 min;Under these conditions
extraction amounts of rosmarinic acid
salvianolic acid B
cryptotanshinone and tanshinone ⅡA were 0.33
11.19
0.63 and 0.59 g·g-1
respectively.Compared with heating reflux extraction in 2010 edition of "Chinese Pharmacopoeia"
Contents of four bioactive components had no significant differences. Conclusion: This optimum extraction process had advantages of low mammalian toxicity
