摘要：
The structures of two new compounds from the root bark of Turraeanthus mannii (Meliaceae) were determined as (3R,4R,3'R,4'R)-6,6'-dimethoxy-3,4,3',4'-tetrahydro-2H,2'H-[3,3']bichromenyl-4,4'-diol (1) and 15-acetoxy-labda-8(17), 12E, 14Z-trien-16-al (2) by means of spectroscopic analysis. Five further known compounds including one coumarin derivative, one chromenone, two labdane diterpenes and one pregnane steroid have been isolated from the same source. In antifungal and cytotoxic assays, 15-acetoxy-labda-8(17), 12E, 14Z-trien-16-al (2) was highly active against Mucor miehei and Artemia salina, respectively. (C) 2012 Phytochemical Society of Europe.
