Abstract
Three new biflavonoids, named (2 Rγ S)-3′-methoxy-8-methylsocotrin-4′-ol (1), (2 Sγ R)-3′-methoxy-8-methylsocotrin-4′-ol (2), and (2 Rγ R)-8-methylsocotrin-4′-ol (3), were isolated from Chinese Dragon's blood [Dracaena cochinchinensis (Lour.) S. C. Chen], together with two known ones. The structures of these new biflavonoids were elucidated by a combination of HR-ESI-MS, 1H NMR, 13C NMR, HMQC, and HMBC spectra. The absolute configurations of compounds 1-4 were determined by quantum chemical calculation of the circular dichroism spectrum and comparison with the experimental CD spectrum.
