摘要：
Two new diterpenoids, 6beta-(2-methylbut-2(Z)-enoyl)-3alpha,4alpha,15,16-bis-epoxy-8beta,10betaH-ent-cleroda-13(16),14-dien-20,12-olide and 10beta-hydroxy-6-oxo-3alpha,4alpha,15,16-bis-epoxy-8betaH-cleroda-13(16),14-dien-20,12-olide, together with the known beta-amyrin, spinasterol, 5,7-dihydroxy-3,8,3',4'-tetramethoxyflavone and 5,7-dihydroxy-3,8,3',4',5'-pentamethoxyflavone have been isolated from the aerial parts of Microglossa angolensis Oliv. et Hiern (Compositae). The structures were elucidated on the basis of spectral studies and comparison with published data. (C) 2005 Elsevier Ltd. All rights reserved.
