Objective:
To study the chemical constituents of Gentiana striata.
Methods:
The constituents were isolated from the whole herb of Gentiana striata by recrystalization, silica gel column chromatography, polyamide column chromatography and Sephadex LH-20,etc. Their structures were elucidated through MS, 1H-NMR, 13C-NMR.
Results:
-8 compounds were isolated and identified as: Desoxyloganin (1), Gmephiloside (2), 5,7,4'-trihydroxy-3'-methoxyflavone (3), (+)-8-hydroxypinoresinol (4) 3S,5R, 6R, 9S-tetra-hydroxymegastigmane (5), Quercetin-3-O-beta-D-glucoside (6), Ferulic acid (7) and Ursolic acid (8).
Conclusion:
All the compounds are isolated for the first time from Gentiana striata.

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.

A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also promote...
Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
