Recent advances in chemical studies on the active principles from plants for fertility regulation

Abstract

Recent results of studies on the active principles from Chinese medicinal plants for fertility regulation in our Institute will be presented. These include abortion principles tanguticacin, daphnegiraldicin,’ daphnegiraldin and 15,16-dihydrodaphnetoxin from some Daphne species; early pregnancy-terminating components pseudolaric acid type compounds from Pseudolarix kaempferi and cycloartane triterpenic acid from Gardenia jasminoides. It also includes separation of optical active d- and l-gossypol—a male’s antifertility agent. The chemical transformation and structure elucidation of these principles will be discussed. © 1986 IUPAC
