Comparative studies on contents of iridoid in different parts of fruit from Gardenia jasminoides / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the contents of iridoid among the fruit, seed, and pericarp from Gardenia jasminoides.</p><p><b>METHOD</b>The contents of geniposide and genipin gentiobioside were determined simultaneously by HPLC. A Kromasil C18 column at 35 degrees C was used with the acetonitrile-0.3% formic acid anhydrous (12 88) as the mobile phases. The detection wavelength was set at 238 nm and the flow rate was 1.0 mL x min(-1).</p><p><b>RESULT</b>The obtained linearity of the two components was better over 0.999 4 and the average recoveries were 99.11%, 98.47%, respectively. The results exhibited the remarkable variation among the different parts of the fruit.</p><p><b>CONCLUSION</b>The contents of the two constituents in seed were higher than in pericarp.</p>
