alkaloids isolated from Voacanga africana staph and the Nuclear Magnetic Resonance (NMR) Spectroscopy Characteristics were summarized. At present

69 alkaloids have been isolated and identified

all are monoterpenoid indole alkaloids. 46 of them are monoterpenes indole alkaloids

and 23 of them are bis (monoterpenes) indole alkaloids. These alkaloids have complex skeletons

rich types

classify them according to the changes of monoterpene structure. Through summarizing the rules of spectroscopic characteristics about alkaloids from Voacanga africana staph

it plays an important role to identify structure and attribution spectral data of this type of compounds.
