Summary
By the systematic entomological examination of chromotographic fractions of sesame oil two pyrethrum synergists, sesamin and sesamolin, were found to account for practically all the synergistic activity of the oil. Sesamolin, which had not been known to be synergistic, is about five times as active as sesamin and, even though usually present in smaller amount than sesamin, it is believed to account for most of the synergistic activity in sesame oil.
Because of sesamolin’s marked synergistic activity, studies on its chemistry were made, and some of its chemical properties are reported. The studies have indicated a close similarity between sesamin and sesamolin, and a tentative chemical formula for sesamolin has been proposed as a basis for future work.
Infrared absorption spectra of sesamin and sesamolin are reported.
