• 説明

  Rauwolfia (Luo Fu Mu) is derived from the plants Rauvolfia verticillata (Lour.) Baill. and R. yunnanensis Tsiang, and the root is usually used as its medicinal part. R. verticillata (Lour.) Baill. var. hainanensis Tsiang and R. vomitoria Afzel. ex Spreng have been also used as traditional Chinese herb.
  Rauwolfia is one of the important traditional herbs in southern China. Its scope of treatment includes cold, fever, sore throat, headache, and dizziness caused by hypertension, abdominal pain and diarrhea, scabies, and so on. Rauwolfia is also used to treat insomniac dizziness, bruises, sprains, and venomous snake bites in folk.
  In the “Flora of China,” 135 species of Rauwolfia were recorded, mostly distributed in the tropics and subtropics, a few in the temperate regions. There are nine species, four varieties, and three cultivated species in China.

• 来歴

  Since 1930s, abundant studies have been focused on the Rauwolfia plants. So far, a total of 91 alkaloids were separated from Rauwolfia, and the identification of the chemical structures was obtained, including 2 non-indole alkaloids (thebaine and papaverine) and 89 indole alkaloids . In accordance with the basic framework, indole alkaloids can be divided into seven classes, such as the ajmaline class, the

• 使用

  An antiarrhythmic agent isolated from Rauwolfia serpentina.

• 定義

  ChEBI: A monoterpenoid indole alkaloid that consists of ajmalan substituted at positions 17 and 21 by hydroxy groups.

• 薬理学

  Anti-arrhythmic R. serpentina (She Geng Mu) is the first anti-arrhythmic herbal medicine in the psychiatry history. Ajmaline has a potent anti-arrhythmic effect for treating atrial and ventricular arrhythmias and also has a good effect on the treatment of Wolff-Parkinson-White syndrome. Ajmaline plays a main role in decreasing the permeability of sodium ion on the myocardial cell membrane by moderately inhibiting the sodium channel. The electrophysiological effect of ajmaline is similar to that of quinidine, but it is stronger than quinidine.
  In addition, ajmaline has a mild anti-sympathetic effect. It affects sympathetic nerve endings to release more sodium, dilate the coronary artery, relax vascular smooth muscle, and then decrease blood pressure. Therefore, it is suitable for clinical treatment of atrial and ventricular premature beats, pre-excitation syndrome with supraventricular tachycardia, but not suitable for the treatment of paroxysmal
  atrial fibrillation and sinus tachycardia.

• 臨床応用

  Ajmaline has the anti-arrhythmic effects for the treatment of atrial or ventricular extrasystoles, paroxysmal supraventricular or ventricular tachycardia, and paroxysmal atrial fibrillation. The lethal dose for human ranged from 100 to 500?mg/kg.

• 純化方法

  Ajmaline crystallises from MeOH or EtOAc containing a little H2O to give the trihydrate m 158-160o. This loses 1H2O at 110o and all H2O at 150o. [Beilstein 23 III/IV 3212.]
