Conversion of 15-OH-epiNCC (6epi) to epimeric 15-OMe-epiNCCs (5epi and iso-5epi) and to YCC 7: HPLC analyses of acidic solutions of 6epi in 100 mm aq. buffer/MeOH 7/3 (v/v) that were stored for 5 h in the dark at ambient temperature. At pH 3, 6epi was largely consumed, giving similar amounts of 5epi and iso-5epi and of YCC 7.
