Figure 1

HPLC chromatograms at 254 nm of S. bimaculata (A-ETH, B-DTH, C-standard mixture): (1) 1-O-glucosylcorymbiferin, (2) 1,3-dihydroxy-4,5-dimethoxyxanthone, and (3) corymbiferin. The HPLC profiles were analyzed with an autosampler and a DAD detector at 0.8 mL/min using gradient elute as follows: solvent methanol and solvent formic acid aqueous (0.1%).
