摘要：

The rare series of doubly-linked proteracacinidin-type oligoflavanoids is extended by identification of four new analogues, oritin-(4 alpha-->7, 5-->6)-epioritin-4 alpha -ol 3, oritin-(4 beta-->7, 5-->6)-epioritin-4 alpha -ol 5, epioritin-(4 beta-->7, 5-->6)-epioritin-4 alpha -ol 7 and epioritin-(4 beta-->7, 5-->6)-oritin-4 alpha -ol 9. The same sources also afforded epioritin-(4P-->5, 3-->4)-oritin-4 alpha -ol 11 possessing a rare (4 beta-->5)- as well as a unique (3-->4)- ether linkage. Their structures and absolute configurations were established via spectroscopic methods. (C) 2001 Elsevier Science Ltd. All rights reserved.
