3 acetylaconitine/aconitum

The effect of the Aconitum alkaloids aconitine, 3-acetylaconitine, lappaconitine, and N-desacetyllappaconitine to inhibit [3H]noradrenaline uptake was investigated in rat hippocampal synaptosomes. Aconitine and 3-acetylaconitine, which are known to activate sodium channels, had comparable inhibitory

The chemical constituents from Aconitum richardsonianum var. pseudosessiliflorum were investigated. The roots of this plant were extracted three times with 90% EtOH at the room temperature. The ethanol extracts were combined and concentrated under reduced pressure to yield residue, which was

Three diterpenoid alkaloids were isolated from Aconitum sinomontanum var. angustius distributed in south Gansu. They were identified as ranaconitine (I), lappaconitine (II), 3-acetylaconitine (III) on the basis of spectral evidences (UV, IR, HNMR, 13CNMR, MS).

OBJECTIVE To study the processing principles of different processed products of Aconitum pendulum. METHODS Using high performance liquid chromatography and acute toxicity test to compare the changes in chemical composition and toxicity of the roots and processed products of A. pendulum. RESULTS The

Five constituents were isolated from Aconitum szechenyianum Gay. The structures of these compounds were identified as beta-sitosterol (I), aconitine (II), 3-acetylaconitine (III), songorine (IV) and a new compound whose structure was elucidated to be szechenyine (V) on the basis of UV, IR, 1HNMR,

Three new C19-norditerpenoid alkaloids (1-3), along with two known C19-norditerpenoid alkaloids (4-5) have been isolated from Aconitum szechenyianum. Their structures were established by extensive spectroscopic techniques and chemical methods as szechenyianine A (1), szechenyianine B (2),

Extracts of the plant Aconitum spec. are used in traditional Chinese medicine predominantly as anti-inflammatory and analgesic agents, the latter allegedly equally potent as morphine but without any habit-forming potential. As the only pharmacologically active compounds, the C19 diterpenoid alkaloid

We have recently studied several natural product constituents which have effects on the CNS. (1) Tetrahydropalmatine (THP) and its analogues were isolated from Corydalis ambigua and various species of Stephania. (+)-THP and (-)-THP possess not only analgesic activity, but also exert
