Abstract:
OBJECTIVE To study the technological parameters of the purification process of ginsenoside Rb
1 in Shenxue capsules by macroporous adsorption resin. METHODS Measured the content of ginsenoside Rb
1 by HP1100, the HPLC conditions were ZORBAX SB-C
18 column(4.6 mm×250 mm, 5 μm); the detector wavelength was 203 nm; the mobile phase was acetonitrile-water(30∶70). The type of resin was selected by the resin adsorption, elution volume ratio and the content of ginsenoside Rb
1. At the same time, wash solvent was selected and the L
9(3
4) orthogonal experiment was carried out to study the elution conditions, in order to determine the purification technological parameters of macroporous adsorption resin. RESULTS The linear of ginsenoside Rb
1 had a good relationship from 0.752 μg to 9.4 μg. Determine the washing solvent solution was 0.5 mol·L
-1 NaOH and the optimal elution conditions were: extraction after standing for 12 h in column, with 15 times 60% ethanol, and the fiowrate was 1.0 mL·min
-1. CONCLUSION The method was simple and exclusive, which can be available to enrich ginsenoside Rb
1 in Shenxue capsules.
