A relatively small amount of space was devoted to the triterpenes in volume 14 of the encyclopedia, but the recent increase in research on these compounds has necessitated a separate book to bring the data up-to-date. Thus, the literature in this supplement covers the period 1937 to 1946, and with regard to chemical structures the literature is reviewed up to 1952. The book covers derivatives of the pentacyclic terpenes of the α- and β-amyrin groups, lupane and heterolupane groups, the tetracyclic triterpenes, and triterpenes with an unknown number of atom rings.
