[HPLC determination of iridoids in Cape jasmine Frvit (Zhizi)]
1National Institute for the Control of Pharmaceutical and Biological Products, Beijing.
Abstract:
Four iridoid constituents: geniposide, gardenoside, geniposidic acid and genipin-1-beta-gentiobioside, have been separated by using an ODS (7 microns) column with gradient elution. The iridoid contents of the crude drug were quantified by peak height ratio. Thirty-one specimens from various sources were analyzed.
