Constituents of Dragon's Blood. 5. Dracoflavans B1, B2, C1, C2, D1, and D2, new A-type deoxyproanthocyanidins.[Pubmed: 9358637]

METHODS AND RESULTS:
From Dragon's Blood, a resin produced by plants of the genus Daemonorops (Palmae), six new A-type flavanoid deoxyproanthocyanidins(Dracoflavan B1, Dracoflavan B2, Dracoflavan C1, Dracoflavan C2, Dracoflavan D1, and Dracoflavan D2, new A-type deoxyproanthocyanidins.) have been isolated.
CONCLUSIONS:
Their structure and stereochemistry, established by chemical degradation and extensive NMR analysis, is consistent with a mechanism of formation common to other constituents of the resin, which involves oxidation of a 6-methylflavan to a quinonemethide, followed by coupling with another flavan moiety.
