Phytochemical study of the Salvia santolinifolia root extract resulted in the isolation of one new quinone diterpenoid, aegyptinone E (1) as well as two known ones, aegyptinone A (2) and aegyptinone D (3). All the isolated compounds were reported for the first time from S. santolinifolia. Spectroscopic analyses including 1D and 2D NMR and HRESIMS were used to determine the chemical structures. Aegyptinone A (2) showed moderate antibacterial activity against Staphylococcus aureus, Staphylococcus epidermis, and Bacillus subtilis with MIC of 25 lg/mL.
