Momordicine

Last updated

A momordicine is any of several compounds found in the bitter melon vine, Momordica charantia. They are glycosides of cucurbitane derivatives. [1] They include

Momordicine II and IV can be extracted from the leaves of M. charantia by methanol. They have been found to deter egg-laying of the leaf mining fly (Liriomyza trifolii) at a combined concentration of 96 μg/cm2. [1]

Momordica foetida is a perennial climbing vine native of tropical Africa, closely related to the bitter melon and balsam apple. Its species name ("bad-smelling") refers to its unpleasant smell. It was previously named M. morkorra and M. cordata (Cogn.)

Charantin is a chemical substance obtained from the Asian bitter melon, reputed to be responsible for the hypoglycaemic properties of those plants. It was identified by Lolitkar and Rao in 1960. It was also found in the similar African species M. foetida, by A. Olaniyi in 1975, under the name foetidin.
