Abstract
Seventy constituents were identified by GC and GC/MS analysis of the oils from the leaves and flower tips, stalks and roots of Elyonurus hensii Schum. The compounds p-cymene, p-mentha-2,8(9)-dien-1-ol, p-mentha-1(7), 8-dien-2-ol, 2-undecanone, 2-tridecanone, intermedeol and aristolone characterize and discriminate the underground and aerial parts of the plant.
