HPLC-diode array detector (HPLC-DAD) chromatograms of the major components of 5-uRCK or 5-uRCC and their fractions. The peak with a retention time of 16.5 min was assigned to ellagic acid. Ellagic acid was identified at a wavelength of 254 nm. Chromatograms of standard ellagic acid (A), 5% ethanol extracts of uRCK or uRCC (B), n-hexane fractions of 5-uRCK or 5-uRCC (C), chloroform fractions of 5-uRCK or 5-uRCC (D), ethyl acetate fractions of 5-uRCK or 5-uRCC (E), n-butanol fractions of 5-uRCK or 5-uRCC (F), and water fractions of 5-uRCK or 5-uRCC (G). (H) The amount of ellagic acid in the extracts and fractions of 5-uRCK or 5-uRCC. The data are represented as the means ± SDs.
