result sql = OBJECTIVE : To establish a method for comparing the differences between fresh and dried ginger juice.

METHOD : The RP-HPLC fingerprint method was performed on an Alltech C18 column (4.6 mm x 250 mm, 5 microm) with mobile phase in gradient elution composed of A-acetonitrie and B-water at a flow rate: 0.8 mL x min(-1). The detecting wavelength was 280 nm, and the column temperature 25 degrees C.

RESULT : There was no significant difference among the same breed ginger juice of different batches. But there was significant difference between crushed ginger juice and the boiled juice. Trytophan, 6-gingerol were common constituents of the three kinds of ginger juice, the fresh ginger and the dry ginger. Besides, 6-shogaol emerged in the boiled juice.

CONCLUSION : The RP-HPLC fingerprints spectrum can be used to distinguish different ginger juices. And the crushed juice of fresh ginger have the same chemical consititents with the fresh ginger.
