[Comparison of chemical constituents in different parts of Gardenia jasminoides based on multiple wavelength HPLC-DAD].

Seven compounds(deacetylasperulasidic acid methyl ester, gardenoside, chlorogenic acid, geniposide, crocin-Ⅰ, crocin-Ⅱ, chikusetsu saponin Ⅳa)were determined simultaneously by multiple wavelength HPLC with diode array detector(DAD) in different parts of Gardenia jasminoides. The results showed that these components in different parts of G. jasminoides had a different distribution, and there was a large difference in content of each component. Geniposide was mainly distributed in fruits and leaves; chikusetsu saponin Ⅳa was mainly distributed in roots and stems; crocus glycosides existed mainly in fruits; chlorogenic acid had a higher distribution in leaves and stems; gardenoside had a higher distribution in leaves and roots, while ceacetylasperulasidic acid methyl ester had a higher distribution in roots and stems. Based on the analysis of the chemical composition and content difference in different parts of G. jasminoides, the basis for the comprehensive utilization and quality evaluation of resources of G. jasminoides was provided.
