title: A new rearranged tricyclic abietane diterpenoid from Salvia chloroleuca Rech. f. & Allen.
abstract: Phytochemical investigation of the roots of Salvia chloroleuca led to the isolation and identification of a new rearranged abietane diterpenoid (1). Its structure was elucidated by interpretation of the 1D and 2D NMR spectra and completed by the analysis of the HR-ESI-MS data. Compound 1 is the secondly reported compound on a rearranged tricyclic abietane (4,5-seco-5,10-friedo-abietane) diterpenoid with a ketal functionality between C-2 and C-11. A plausible biosynthetic pathway of 1 was also proposed.
