Abstract:
Two new sesquiterpenoid glycosides, nicotabalactonecoside (1) and nicotabadiolcoside (2), along with four known terpenoids (3-6) were isolated from the leaves of Nicotiana tabacum. The structures of compounds 1 and 2 were determined as dihydrodeacetylphytuberin-2-one 11-O-β-D-glucopyranoside and 1,2-dehydro-4-epieremophil-9-ene-11,12-diol 12-O-β-D-glucopyranoside by extensive spectroscopic analyses (HR-ESI-MS, UV, IR, 1D, and 2D NMR) and chemical method. Compound 1 is an unusual phytuberin-type sesquiterpenoid with a 6/5/5 tricyclic system.

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...
