Strychnos nux vomica Loganiaceae

L. was first isolated in 1884 from an extract of the poison nut tree Strychnos nux-vomica, Loganiaceae). The poison nut tree is indigenous to tropical India and Sri Lanka. L. also occurs in European bog bean (water trefoil) Menyanthes trifoliata, Menyanthaceae) and in... 

Methamphetamine, derived from ephedrine, and cocaine [1], and caffeine are known as CNS stimulants, though the strength of each activity is different. On the other hand, strychnine isolated from the seed of Strychnos nux-vomica (Loganiaceae) stimulates the reflex function of the spinal cord. That is to say, it is a stimulant of the spinal cord in the CNS. 

Strychnos nux-vomica (Loganiaceae) is a tree that grows wild in India, Sri Lanka, and the northern area of Australia. The seeds of this plant are known as Machin-shi (in Japanese) or vomica (Strychni Semen), and they are used for maintaining health of the stomach at a medicinal dose. The seeds are also the source of strychnine nitrate, and have found use for heart and lung diseases and for Raynaud s disease.

The chemical structure of cycloartanes is based on the 9b,19-cyclo-5a-lanostane (cycloartane) (I) skeleton. The term cycloartane evolved from the first representative of this class to be structurally characterized, cycloartenol, which was prepared from the corresponding ketone cycloartenone. Barton gave these names to the compounds because the ketone was isolated from latex of Artocarpus integrifolia L. (Moraceae) fruit [1]. Then, Spring et al. isolated cycloartenol from Strychnos nux-vomica L. (Loganiaceae) [2]. It sorni became clear that cycloartenol and its slightly polar analogs were widely distributed in the plant world.
