A new sesquiterpene lactone C15H20O2 with mp 79–79.5°C, [α] D 20 +105° (chloroform) has been isolated from the roots ofInula grandis Schrenk., and we have called it “igalan.” On the basis of chemical and spectral characteristics, it has been established that its most probable structure is eleman-8,11-olide.
