To underline the importance of alkaloids in this respect, the chapter “Antitumor Alkaloids,” written by internationally known experts, became Volume XXV of The Alkaloids. ‘‘Antitumor Alkaloids, containing more than 2000 literature references, dis- ” cusses the biological properties of alkaloids isolated from 120,000 plant extracts representing over 6000 genera of plants in antitumor screenings and presents data on the therapeutic evaluation of interesting candidates in humans. The chapter does not discuss the therapeutically important group of dimeric Vinca alkaloids, which will be presented in similar detail in a future volume of The Alkaloids. Arnold Brossi
