摘要：
Three new azaphilone derivatives designated falconensins E (5), F (6), and G (7) were isolated from the mycelium of Emericella falconensis, along with falconensins A (1), B (2), C (3), D (4), and H (8), and three hopane-type triterpenes, zeorin (9), hopane-7 beta,22-diol (10), and hopane-6 alpha,7 beta,22-triol (11). The structures of 5-7 were confirmed by spectroscopic investigation and chemical correlations. The absolute stereochemistry of falconensins A (1) to G (7) was also established.
