Objective: To prepare chemical constituents and establish an HPLC method for determining these constituents in Gardeniae Fructus. Method: The chromatographic separations were obtained on a Kromasil C18 column (4.6 mm×250 mm
5 μm) with the mobile phase consisting of acetonitrile and 0.1% phosphoric acid aqueous solution (18: 82) at a flow rate of 1.0 mL · min-1. The detection wavelength was set at 327 nm
and the column temperature was 40 ℃. Result: 6"-p-coumaroyl genipin gentiobioside(1) and 3
5-di-O-caffeoyl-4-O-(3-hydroxy-3-methyl) glutaroyl quinic acid(2) were isolated from Gardeniae Fructus. These two constituents showed good linear relationship in range of 0.118 8-1.188 μg and 0.122 8-1.228 μg
respectively. The average recoveries were 99.23%(RSD 2.4%) and 100.4%(RSD 2.3%). Harvesting time has significant effect on the contents of the two constituents. Conclusion: The tests reflect the variation of the constituents in different harvesting time and the methods established are suitable for the quality improvement of Gardeniae Fructus.
