Objective:
To study the chemical constituents from Astilbe myriantha.
Methods:
The constituents were isolated and purified by column chromatography methods and recrystallization. Their structures were identified on the basis of physiochemical properties and special analysis.
Results:
Ten compounds were isolated from 95% ethanol extract of Astilbe myriantha and their structures were identified as: beta-sitosterol (1), methyl p-hydroxy benzoate (2), ferulic acid (3), bergenin (4), gallic acid (5), (+)-catechin (6), 3beta-acetoxy-6beta-hydroxyolean-12-en-27-oic acid (7), 3beta-hydroxyolean-12-en-27-oic acid (8),3beta,6beta-dihydrolean-12-en-27-oic acid (9) and 3beta-hydroxyurs-12-en-27-oic acid (10).
Conclusion:
Compounds 1-7 are isolated from this plant for the first time.

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.
