Uses

An antiarrhythmic agent isolated from Rauwolfia serpentina.

Uses

For use as an antiarrhythmic agent.

Definition

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

Manufacturing Process

Ajmaline isolated from Rauwolfia sp. roots: Rauwolfia serpentine Benth., Rauwolfia vomitoria Afr., Rauwolfia canescens L.
Threshed roots of Rauwolfia canescens L. extracted with 5% solution of acetic acid at room temperature for 24 h. Then extract was decanted to flask. This extract was alkalified with ammonia (alkaloid salts were converted to alkaloid bases). The obtained thus method solution was extracted with chloroform 3 or more times. Then chloroform extract was chromatographed on column through Al2O3 sorbent. After chromatography ajmalin was obtained, which had melting point at 205°C (recyrstallization from methanol).

Therapeutic Function

Antiarrhythmic

Purification Methods

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.]
