Abstract:
Two alpha-pinene-type monoterpenes, 7-hydroxymyrtenol (1) and 7-hydroxymyrtenal (2), a inositol derivative, (+)-quebrachitol (3) and two p-menthene triols (4 and 5), in addition to two known compounds were isolated from the aerial parts of Artemisia suksdorfii. The structures of the isolated compounds were established by analysis of spectroscopic data (IR, HR-MS, (1)H and (13)C NMR), including high-field 2D NMR techniques ((1)H-(1)H COSY, HMQC, HMBC and NOE) and in case of 3 was confirmed by X-ray analysis.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
