• Dehydropachymic acid contents in the crude drug, hoelen, was determined by HPLC using a Develosil P-5 (4.6×250 mm) column with CH_3CN-H_2O-AcOH (70:30:1) as a mobile phase, and monitoring absorption at 242 nm at 40°. The hoelens examined were 16 samples commercially obtained in Osaka, and 4 samples collected in Ishikawa prefecture. The dehydropachymic acid contents in the 20 hoelens were in a range of 0.013 to 0.034 %. The present method of quantitative analysis of dehydropachymic acid is applicable to the determination of dehydropachymic acid contents of the Chinese medicine, Sho-hange-ka-bukuryo-to.
