The Chemical Constituents of Piper Methysticum Or, The Chemical Constituents of the Active Principle of the Ava Root

"The Chemical Constituents of Piper Methysticum" by Alice A. Ball is a scientific publication presented as a master's thesis in the early 20th century. It discusses the chemical properties and constituents of the kava root, specifically focusing on the active ingredients responsible for its physiological effects. The work is grounded in original research and exploration of the extraction and analysis of the substances found within the kava plant. In this detailed exploration, Alice A. Ball lays out a comprehensive study of the methods used to extract the active components of the kava root, including the techniques of resin separation and the identification of various chemical compounds like methysticin and its derivatives. The thesis not only describes the chemical analysis and the methods of experimentation but also delves into the physiological actions observed in preliminary tests, particularly on rabbits. Through her meticulous research, she concludes that the kava root lacks alkaloidal substances and discusses its psychoactive effects, primarily linked to resinous elements rather than traditional alkaloids. This pioneering work significantly contributes to the understanding of kava's chemical makeup and its implications in both scientific and cultural contexts.

Alice Augusta Ball was an American chemist who developed the "Ball Method" for making ethyl ester derivatives of chaulmoogra oil, which were used as a treatment for leprosy during the early 20th century. She was the first woman and first African American to receive a master's degree from the University of Hawaiʻi, and was also the university's first female and African American chemistry professor. She died at age 24 and her contributions to science were not recognized until many years after her death.
