New axane and oppositane sesquiterpenes from Teclea nobilis.
Two new isomeric axane and oppositane sesquiterpene derivatives, named teclenone A (1) and teclenone B (2), were isolated from the aerial parts of Teclea nobilis. Their structures have been established on the basis of (1)H and (13)C NMR spectral data, notably 2D NMR (1)H-(1)H COSY, (1)H-(13)C HMQC, (1)H-(13)C HMBC, and (1)H-(1)H NOESY experiments. This appears to be the first report of the rare axane and oppositane sesquiterpenes from the plant family Rutaceae.
