ABSTRACT
Curcumin contents in different cultivars and organs of ginger, Zingiber officinale Roscoe were analyzed by SPE-HPLC method. Dried powders of rhizomes were extracted with 75% ethanol, purified through an Envi-18 SPE column, followed by a reversed-phase HPLC analysis. Contents of curcumin in 13 cultivars of ginger from six provinces varied from 0.75 to 5.0 mg/100 g dry weight, a 6.7-fold difference between the high and low ends. However, all of them are much lower than that in turmeric, Curcuma longa L. (2857 mg/100 g dry weight). Curcumin was high in pulp and low in peel of rhizome, and the lowest in aerial parts of gingers. Results indicated that curcumin levels in gingers were mainly determined by their cultivars. Locations of cultivation had, but less effect on it. Organically grown ginger contains significant higher curcumin.
