Strychnos Loganiaceae

An alkaloid present in the seeds of Strychnos nux-vomica and other species of Strychnos (Loganiaceae). 

As described previously, the origins of the three types of curare are the extracts of Chondodendron (Menispermaceae) and/or Strychnos (Loganiaceae) plants. Among them, the toxic components of Strychnos plants are C-curarine and C-toxiferine I, etc.These constituents are alkaloids derived from tryptophan and are described in the next (Section 2.15).The C- is the initial of calabash. On the other hand, the toxic principle of tubocu-rare is d-tubocurarine, an alkaloid derived from phenylalanine. The alkaloid was first isolated as a hydrochloride from tubocurare and is preserved in the Museum of the British Society of Pharmacy [1]. The chemical structure of d-tubocurarine was first proposed as a bisbenzylisoquinoline with two quaternary ammonium moieties. This was revised in 1970 to be the structure with one tertiary and one quaternary amine after X-ray crystallographic analysis [2]. 

Alkaloids are particularly important in arrow poisons based on Chondrodendron (Menispermaceae) and Strychnos (Loganiaceae) species, but they are the active ingredients of arrow poisons from many other species as well (Cordell, 1978). 

This association of sempervirine with yohimbine is of biological interest since the former alkaloid is derived from a plant of the Loganiaceas in which alkaloids of the strychnos group seemed to be characteristic, whereas the yohimbine group of alkaloids have so far only been found in the Apocynaceae and Rubiace c.

Strychnos madagascariensis Spreng. ex. Baker, [umkhwakhwa, blak monkey orange] (Loganiaceae) leaf decoction is the only Swazi plant documented that is used for snakebite. The leaf contains alkaloids, flavonoids, glycosides, polyphenols, saponins and steroids (15). The frait is edible (23). The stem bark is for stomachache (11).
