Flavonoids And Essential Oils Of T. Vulgaris And T. Schimperi

The essential oils of the leaves of Thymus species ( I vulgaris and T. schimperi) grown inrndifferent parts of Ethiopia were investigated using GC and GC-MS. The results indicated thatrnT. vulgaris was rich in thymol (>40%) while the components of the oil of T. schimperi grownrnin different regions vary considerably. The major components of T. schimperi obtained fromrnDinshu, Maichew and Science Faculty Arobertum were thymol (42-50%) linalool (30%) andrncarvacrol (44%) respectively. Plant material purchased from Debre Sina was similar in itsrncomposition with that from Dinshu.rnSolvent extraction of the aerial parts of T. vulgaris yielded the flavonoids naringenin andrneriodicytol. Their structures were determined by spectroscopic methods
