Chemical constituents from Phlomis bovei Noë and their chemotaxonomic significance
2020
Abstract A phytochemical investigation of the leaves and roots of Phlomis bovei Noe (Lamiaceae) led to the isolation of sixteen compounds, including iridoids (1, 2, 3), megastigmanes (4, 5), phenylpropanoids (6, 7, 8, 9, 10), lignans (11, 12, 13, 14), a nortriterpene (15), and a phenyl glucoside (16). Compounds (1, 2, 4, 5, 6, 10) were obtained from the leaves and compounds (1, 2, 3, 7, 8, 9, 11, 12, 13, 14, 15, 16) were isolated from the roots. Compounds 1 and 2 were found both in the leaves and in roots. The compounds were identified by analysis of 1D- (1H, 13C), 2D-NMR (1H–1H COSY, TOCSY, ROESY, HSQC, HMBC) spectroscopic data, mass spectrometry (ESI- and HR-ESI-MS), and by comparison wit…
