To investigate anticancer effects of Kaempferia parviflora, rhizomes of K. parviflora were extracted with supercritical $CO_2$ fluid and ethanol under various extraction conditions. Antiproliferative activity of these extracts was evaluated against human cervical cancer HeLa and human gastric adenocarcinoma AGS cell lines. Supercritical $CO_2$ fluid extracts (SFEs) of K. parviflora showed more potent antiproliferative activity than the ethanol extracts against both cell lines, because SFEs contained higher concentration of polymethoxyflavones (PMFs) (72-89 wt%) than the ethanol extract (55-70 wt%). From the compositional analysis of the extracts, 5,7-dimethoxyflavone (1) in K. parviflora was proposed as a potent anticancer PMF. Furthermore, it was found that PMFs with more methoxy groups do not necessarily show better anticancer activity.
