Volume 4 of the Encyclopedia of the Alkaloids covers the literature to the end of 1981 and includes those compounds which have been discovered since Volume 3 was published in 1977. There is also a small number of entries giving recently determined structure or addi- tional information regarding alkaloids given in the preceding three volumes. It is a great pleasure to thank the staff of the John Rylands Science Library of the Univer- sity of Manchester for kindly providing me with access to the literature on this subject.

Indefinite I I OAc The root bark of Rauwolfia nitida yields this yohimbine-type alkaloid which has been ob- tained as an off-white amorphous powder having no definite melting point. The base is lae- 2 vorotatory with a specific rotation of [aJ5 -89 (c 0.
01, CHCI ) and gives an ultraviolet 3 spectrum in MeOH with absorption maxima at 225,284 and 290 nm. The structure has been established from chemical and spectroscopic analysis. M. A. Amer, W. E. Court, Phytochem. , 20,2569 (1981) 14-ACETYLBROWNINE ___ :(OMe M. p.
