| The air- dried and ground rhizomes of Eremostachys macrophylla Montbr.
& Auch., as wild-growing plant in East Azerbaijan province, of Iran, were
extracted with n-hexane, dichloromethane (DCM) and methanol (MeOH)
solvents using a soxhlet apparatus. The 10% MeOH in water Sep-Pak
fractions of the MeOH extract was subjected to preparative reversed-
phase high performance liquid chromatography (RP-HPLC) and the
isolated pure compounds were identified by one- dimensional nuclear
magnetic resonance (1D
NMR) spectroscopic technique. The obtained
results showed the presence of two pure components, 6- Hydroxyl
Loganin, (1) and Lamalbide (2) with iridoid structures. The results
demonstrated the rhizomes of E. macrophylla could be a good source of
iridoids. |
