Loganiaceae

The existence of alkaloids in the rhizome and roots of the North American plant Gelsemium sempervirens Ait (Loganiaceae) was first demonstrated by Wormley and later a crystalline alkaloid, gelsemine, was isolated by Gerrard. Thompson found in addition to gelsemine an amorphous alkaloid, gelseminine. Gelsemine was later examined by... 

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. 

Such alkaloids can be found particularly in the Myristicaceae, Malpighiaceae, Rutaceae, Apocynaceae, Rubiaceae, Loganiaceae, and Convolvulaceae. Such compounds are also found in mushrooms from the genera Conocybe, Panaeolus, Psilocybe, and Stropharia (Agaricaceae), which where used by the Aztecs of pre-Columbian America for their psilocin.

The majority of indole alkaloids have been isolated from the three plant families, Loganiaceae, Apocynaceae, and Rubiaceae. Among this last family, the genus Pauridiantha has received limited attention, although about 30 different species have been identified and some of them are still being used in native medicine.
