Aromatic Biodiversity among Three Endemic Thymus Species of Iran

Abstract

The arom. content of three Thymus species, T. persicus, T. daenensis, and T. kotschyanus, was assessed using gas chromatog. (GC) and GC-mass spectrometry anal. Aerial parts of T. persicus, T. daenensis, and T. kotschyanus yielded 0.2, 0.7 and 1.1% of essential oils, resp. The major components in the oil of T. persicus are thymol, p-cymene, γ-terpinene, carvacrol, linalool and borneol. T. daenensis contain 73.9% thymol, 6.7% carvacrol, 4.6% p-cymene, 1.5% β-bisabolene and 1.4% terpinen-4-ol. T. kotschyanus oil contain 69.8% carvacrol, 6.8% thymol, 3.9% γ-terpinene, 3.2% p-cymene, 3.2% borneol and 1.3 β-caryophyllene. [on SciFinder(R)]
