Abstract

Investigation of the methanol extract of the roots of Gnidia involucrata (Thymelaeaceae) led to the isolation and characterization of two new 3,8"-biflavonoid diastereoisomers, named GB-4 (6a) and GB-4a (6b). Their absolute configurations were determined in mixture by on-line LC/CD measurements, which also allowed the revision of absolute configurations of the billavanoids GB-1 and GB-2, and the configurational assignment of GB-3.
