Phytochemical investigation on the stems of Trigonostemon flavidus resulted in the isolation of five new 3,4-seco-diterpenoids, trigoflavidones A-E (1-5), structurally related to the main co-occurring known 3,4-seco-sonderianic acid (6) and 3,4-seco-sonderianol (7). Compound 4 possesses new 3,4-seco rearranged ent-pimarane skeletal type, characteristic of a vinyl group at C-8, while 5 features a unique five-membered ring (C-1) fused with a cyclopropane ring (C-2). The structures of the new compounds were established by a combination of spectroscopic data and computational methods. Compounds 1-7 were tested for their cytotoxicities on HL-60, SMMC-7721, A-549, MCF-7, and SW480 human tumor cell lines. (c) 2012 Elsevier Ltd. All rights reserved.
