What is the the scientific name of the chemical in the coca plant from wich cocaine is produced that causes the subject to feel under the influence of this narcotic?, also is this the only species of plant thet contains this chemical?

Answer 1

Pharmacological aspects of Coca.


The pharmacologically active ingredient of coca is the alkaloid cocaine which is found in the amount of about 0.2% in fresh leaves.

Besides cocaine, the coca leaf contains a number of other alkaloids, including Methylecgonine cinnamate, Benzoylecgonine, Truxilline, Hydroxytropacocaine, Tropacocaine, Ecgonine, Cuscohygrine, Dihydrocuscohygrine, Nicotine and Hygrine.

Some of these non-psychoactive chemicals are still used for the flavouring of Coca-Cola. When chewed, Coca acts as a stimulant to help suppress hunger sensations, thirst, and fatigue. Some anesthetics such as Novocaine are derived from the coca plant. The LD50 of coca extract is 3,450 mg/kg, however, the LD50 of the extract based on its cocaine content is 31.4 mg/kg, indicating that the coca leaf contains constituents other than cocaine that may contribute to a toxic effect of the plant.

Answer 2

Cocaine (or crack in its impure freebase form) is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant.

Tropane alkaloids occur in plants of the families Solanaceae (mandrake, henbane, deadly nightshade, Datura species) and Erythroxylaceae (coca).
