| Abstract
Background: Eremostachys macrophylla Montbr. & Auch. is one of the wild growing species of
herbs found in East Azerbaijan province of Iran. These species are used in folk medicine for the
healing of wound, treatment of snake bites, rheumatism and joint pains. The primary aim of this
study was to obtain natural pure compounds and this was done by subjecting the aerial parts of
Eremostachys macrophylla Montbr. & Auch. to phytochemical analysis.
Methods: The air-dried and crushed aerial parts were respectively extracted with n-hexane,
dichloromethane (DCM) and methanol (MeOH) solvents using a soxhlet apparatus. The 10%,
20% and 40% of MeOH in water Sep-Pak fractions of the MeOH extract were subjected to a
preparative reversed- phase high performance liquid chromatography (RP-HPLC). Also, the
isolated pure compounds were identified by one-dimensional nuclear magnetic resonance
(1D-NMR) spectroscopic technique
Results: The results obtained in this study showed the presence of seven pure components; (1)
Lamalbide, (2) Sesamoside, (3) Phlomiol, (4) Verbascoside, (5) Luteolin-7-O- glucoside, (6)
Apigenin-7-O- rutinoside and (7) Kaempferol-3-O- glucoside with iridoid, phenylethanoid and
flavonoid structures.
Conclusion: The results from the study demonstrated that the aerial parts of E. macrophylla
could be a good source of iridoids, phenylethanoids and flavonoids. |
