I-3,II-8)-taxifolin to eriodictolyl (I-3,II-8)-taxifolin (125, 126, 295) (Table 7.6.3). A flavanone-aurone derivative, zehyerin (7A), has been isolated from a Phyllogei-ton species of the Rhamnaceae (371). Larixinol (7B), a (1-3,11-8) biflavonoid derived from unusual coupling of a dihydroflavonol with a flavan-3-ol was isolated recently from Larix gmelini (336).

The Rhizophora stylosa polysaccharide-proanthocyanidin complex is apparently similar to the species isolated from Larix gmelini bark (127). The complex survived repeated chromatography on Sephadex LH-20 and the NMR contained signals consistent with a procyanidin polymer and polysaccharide being present.
