The Chemical Composition of the Essential Oil Obtained from , Wierzb. ap. Heuff monoterpenoid pattern in essential oils are considered to be primarily controlled by genetic factors while compositional variations may result from the differences in ecological conditions. Our present understanding of the relative importance of all the determinants in the formation of secondary me
