Objective: Comparison of diterpene pigments of Fructus Gardeniae on different processing methods with ginger juice. Method: Ginger gardenia were processed in accordance with the "National Traditional Chinese Medicine processing standard" and "Beijing Chinese Herbal Preparation Standards"

the HPLC method were used to determine the content of two ginger gardenia on three diterpene anthocyanin pigment and a diterpene aglycone. Result: Crocin-1 and crocin-2 in two ginger gardenias were significantly decreased

crocin-3 showed no significant changen and the content of crocetin were increased significantly compared with Fructus Gardeniae. Conclusion: It has greater impact on diterpene pigments in two kinds of ginger gardenia

especially on the way of adding ginger juice. The "fired after mixing ginger juice" method is more significant than "adding ginger juice after fired". It is necessary to develop a further research on pharmacological effects of crocin-1 and crocin-2

in order to reveal the processing principle of two kinds of method.
