Two new sesquiterpene lactones, (+)-β-frullanolide and (+)-brothenolide, have been isolated from the liverwort Frullania brotheri STeph. One of them, (+)-brothenolide, has an allergenic property. The absolute structures of these lactones have been established by spectroscopic analysis and chemical transformation.
