Abstract:
Phytochemical study on the ethanol extract of the rhizomes of Curculigo breviscapa led to the isolation of two new norlignans, breviscapin C (1) and breviscaside B (2), together with six known norlignans, curcapital (3), capituloside (4), pilosidine (5), curcapitoside (6), crassifoside H (7), and crassifoside F (8). Their structures were elucidated on the basis of extensive spectroscopic analysis and comparisons of their data with literature values. All the compounds were isolated for the first time from this plant.

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.
