Popis:	Analyses of oils obtained by hydrodistillation of foliage of E. youmonii, E. macrorhyncha, and E. macarthuri from India revealed that the three oils are chemically alike, but for the quantitative differences of the main components. The eudesmol (α- and β-) content in E. macrorhyncha and E. macarthuri is rather similar (15.38% and 18.91% respectively), but much higher in E. youmonii (50.04%). The 1,8-cineol content in E. youmonii (30.70%) and E. macrorhyncha (29.83%) are alike while geranyl acetate (23.84%) content in E. macarthuri is highest amongst the three. E. cinerea oil contains cineol (64.65%), α-terpineol (11.56%) and limonene (12.51%) as the major components. On the whole E. macrorhyncha, E. macarthuri and E. cinerea oils are rich in monoterpenoids (71.16%, 71.90% and 94.55%) whereas that of E. youmonii is rich in sesquiterpenoids (53.37%).
