(HPLC). TLC on silica gel was carried out using CHCl3-MeOH-H2O (:10) as the mobile phase. I and III were detected by UV and II by p-anisaldehyde-H2SO4 soln. HPLC was carried out using a reversed-phase ODS column and MeCN-H2O () as the mobile phase. I and II were detected at 254 nm, while III was detected using a fluorescence detector at 254 nm. The recovery for I, II and III was 86, 96 and 99%, resp. .
