Two new sesquiterpenes (1–2), and one diterpene (3) were isolated from the roots of Salvia palaestina Bentham (Lamiaceae), together with eight known diterpenes and two triterpenes. Their structures were elucidated by 1D and 2D NMR spectroscopy, including 1D-TOCSY, DQF-COSY, ROESY, HSQC, and HMBC experiments, as well as ESIMS and chemical analysis.
