A simple, sensitive and accurate method for separation and determination of the alkaloids, 1-formyl-β-carboline (Ⅰ),. 4, 5-dimethoxycanthin-6-one (Ⅱ), 1-vinyl-4, 8-dimethoxy-β-earboline (Ⅲ) and 1-formyl-4-methoxy-β-carboline (Ⅳ), in Ku-Mu [Picrasma quassioides (D. Don) Benn.] is described.Sample solution was applied at a point 1 cm from the bottom edge of the HPTLC silica gel plate (10 × 10cm). Chloroform (water saturated)—methanol (40:0.5) was used as the developing solvent. The plate was…

Dehydrocrenatidine Inhibits Voltage-Gated Sodium Channels and Ameliorates Mechanic Allodia in a Rat Model of Neuropathic Pain
Electrophysiological characterization and dose-dependently attenuated the mechanic allodynia demonstrated that the analgesic effect of dehydrocrenatidine was likely though the inhibition of neuronal excitability.
