Optimization of Purification Process of Total Alkaloid Extract of Berberis dictyophylla Cortex by Macroporous Resin and Investigation of Its Quality Standard
To optimize purification process of total alkaloid extract of
Berberis dictyophylla
cortex by macroporous resin
and to establish its quality standard.
Method:
2
Acid dye colorimetry was used to investigate the purification process of total alkaloid extract of
B
.
dictyophylla
cortex
the process parameters included concentration of sample solution
speed of sampling
diameter-height ratio of resin column
water washing amount
concentration and dosage of eluent
flow rate of elution
etc.In order to determine the optimum process
HPLC was employed to determine the contents of four alkaloids(magnoflorine
jatrorrhizine hydrochloride
palmatine hydrochloride
and berberine hydrochloride) with mobile phase of acetonitrile-0.1% phosphoric acid aqueous solution for gradient elution and detection wavelength at 270 nm.After being purified
quality standard of total alkaloid extract of
B
.
dictyophylla
cortex was investigated according to the requirements in the 2015 edition of
Chinese Pharmacopoeia
.
Result:
2
Optimal purification conditions were as following: 10 g of HPD100 macroporous adsorption resin with a column diameter-height ratio of 1∶8
sampling solution concentration of 11 g·L
-1
the loading flow rate of 1 mL·min
-1
sampling solution volume of 50 mL
washed with 4 BV of water(1 BV=15 mL) and added 9 BV of 30% ethanol
after being purified
the transfer rate of total alkaloids was
>
80%
and its purity was
>
65%.The quality standard of total alkaloid extract of
B
.
dictyophylla
cortex was established
there were 19 common peaks in the characteristic chromatogram
and the overall similarity was
>
0.99.
Conclusion:
2
This optimized purification process is stable and feasible
and the established quality standard is controllable.
