摘要
A new biflavonoid, 2,3-dihydro-5,5″,7,7,4′-pentahydroxy-6,6＂-dimethyl-[3′-O-4″]-biflavone 1 and two known biflavonoids 2,3＂-dihydroochnaflavone 2 and 2″,3″-dihydro-3′,3-biapigenin 3 were isolated from the herb of Selaginella labordei Hieron. ex Christ. Their structures were elucidated by spectroscopic methods. ？2009 Ke Li Chert. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
