Fingerprint of water-soluble composition of Fructus Gardeniae from different breed and production places / 中成药

ABSTRACT

AIM:To set up the fingerprint chromatograms of chemical principles of Fructus Gardeniae in Jiangxi Province by HPLC. METHODS:The chromatographic seperation was performed on an Eclipse XDB-C_(18) column(4.6 mm?250 mm,5 ?m,Agilent) with a mobile phase consisting of acetonitrile-0.1% phosphoric acid,gradient eluent,at the flow rate of 1.0 mL/min.The UV detection was set at the maximum absorption wavelength at 238 nm for iridoid glycosides and at 440 nm for crocins. RESULTS:Based on the fingerprint chromatograms of water-soluble composition of 12 batches Fructus gardeniae in authentic regions of Jiangxi,we have pinpointed 11 common peaks. CONCLUSION:This method can provide a basis for controlling the quality of Fructus gardeniae and be a means of germplasm resources.
