Abstract:
The Amaranthaceae plant, Pfaffia glomerata, which is so-called as Brazil ginseng, is widely distributed in South American countries. Three new noroleanane-type triterpenes and four known oleanane-type triterpenes were isolated from the roots of P. glomerata. Their structures were determined by spectroscopic methods including 1D and 2D NMR experiments. Their effects on melanogenesis were also reported.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
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.
