ABSTRACT
OBJECTIVE:
To compare the contents of loganic acid,swertiamarin,6′-O-β-D-glucosyl gentiopicroside,gentiopi-croside,sweroside,isoorientin and isovitexin in wild and cultivated Gentiana officinalis,and to provide basis for rational use of G. officinalis.METHODS:
UPLC method was adopted. The separation was performed on ACQUITY UPLC? BEH C18 column (50 mm × 2.1 mm,1.7 μm) with mobile phase consisted of methanol-0.04% phosphoric acid (gradient elution) at the flow rate of 0.3 ml/min. The detection wavelength was set at 242 nm,and column temperature was 30 ℃.RESULTS:
For loganic acid,swertiama-rin,6′-O-β- D-glucosyl gentiopicroside,gentiopicroside,sweroside,isoorientin and isovitexin,a good linearity was obtained in the range of 2.1-537.1 μg,1.05-270 μg,0.92-236 μg,11.1-2 830 μg,0.75-192 μg,0.167-102 μg,0.216-52.80 μg(r≥0.999 5), respectively. Their average recoveries were 97.72%-99.84%(RSD≤3.39%,n=6). The contents of loganic acid,swertiamarin, 6′-O-β-D-glucosyl gentiopicroside,gentiopicroside,sweroside and isoorientin in the wild sample were higher than in the cultivat-ed;the content of isovitexin was lower than the cultivated,but there was no statistical significance(P>0.05). The sum of gentiopi-croside and loganin acid content were all higher than 2.5% in both wild and cultivated samples,and met the requirements of 2015 edition of Chinese Pharmacopoeia(first part).CONCLUSIONS:
The content difference of 7 indicative constituents in wild and cul-tivated G. officinalis is not statistically significant,and the indicative constituents of the pharmacopoeia is qualified.
