Two new abietane diterpenes with rearranged skeleton; aegyptinol and aegyptinone C; have been isolated and identified for the first time from the anti-microbial petroleum ether extract of the roots of Salvia aegyptiaca L. Their chemical structures have been elucidated by interpretation of the detailed 1D-and 2D-NMR spectra, as well as other spectroscopic tools. In addition, full assignment of $^{13}C-NMR$ of aegyptinone B was also conducted for the first time.
