Abstract
Three new diterpenoids, 12,16-epoxy-11-hydroxy-17(15 → 16)-abeo-abieta-8,11,13-trien-7-one (1), 7,12-dihydroxy abieta-6,8,10(5),11,13-quien-20-oic acid 1,20-lactone (2), labda-5(10),13(E)-dien-15-ol (11), one new natural product (2E,6E)-3,7-dimethyl-9-[(1S,6R)-1,2,6-trimethylcyclohex-2-enyl]nona-2,6-dien-1-ol (16) and thirteen known compounds were isolated and elucidated from the excellent antimicrobial active fractions of Rosmarinus officinalis ethanol extract. The structures of the isolated compounds were determined by spectral data analysis and combined with literature reports. Among them, monocyclic diterpenoids (16 and 17) were discovered from rosemary for the first time. All isolated compounds were tested for antimicrobial activity against four strains (B. subtilis, S. aureus, P. aeruginosa, and Fusarium spp.), with six compounds showing very strong inhibitory activity against B. subtilis and four compounds showing strong inhibitory activity against P. aeruginosa.
期刊介绍:
STEROIDS is an international research journal devoted to studies on all chemical and biological aspects of steroidal moieties. The journal focuses on both experimental and theoretical studies on the biology, chemistry, biosynthesis, metabolism, molecular biology, physiology and pharmacology of steroids and other molecules that target or regulate steroid receptors. Manuscripts presenting clinical research related to steroids, steroid drug development, comparative endocrinology of steroid hormones, investigations on the mechanism of steroid action and steroid chemistry are all appropriate for submission for peer review. STEROIDS publishes both original research and timely reviews. For details concerning the preparation of manuscripts see Instructions to Authors, which is published in each issue of the journal.
