A new steroid named Phlomiside (1) has been isolated from the whole plant including
roots from the ethylacetate fraction of Phlomis bracteosa along with four known compounds
namely b-amyrin (2), b-sitosterol (3), stigmasterol (4) and oleanolic acid (5). The structure assignments
are based primarily on two-dimensional (2D)-NMR techniques including correlation spectroscopy
(COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple
bond correlation (HMBC) and nuclear overhauser effect spectroscopy (NOESY) experiments.
