Absolute Configuration, Conformation, and Chiral Properties of Flavanone-(3→8'')-Flavone Biflavonoids from Rheedia acuminata. -The title compounds (I) show considerable chiral stability. The absolute configuration and conformation are determined by circular dichroism, NMR, NOESY; and computational calculations. -(LI*, X.-C.; JOSHI, A. S.; TAN, B.; ELSOHLY, H. N.; WALKER, L.
