Abstract: | The essential oil properties of spearmint (Mentha spicataL.), one of the most important spice plants, were studied and the essential oil components determined using gas chromatography.
The essential oil content of wild-grown spearmint in the region was found to range from 1.00% to 2.00%, and two chemotypes
were identified, one high in carvone (49.53-80.65%) and the other in pulegone (44.9-49.23%). Agronomic and essential oil properties
of cultivated landraces ofM. spicata were also investigated under field conditions during the 1999 vegetation period. The examined spearmint landraces
showed a great variability for each character studied, including yield and essential oil components. The crop was harvested
twice during the vegetation period, and the essential oil content of the landraces varied from 0.90 to 2.70% in the first
harvest and from 1.00 to 3.00% in the second one. Carvone was constantly present as the predominant essential oil in landraces,
except for one sample, which was high in linalool (82.80%). Superior landraces with carvone contents were discovered; their
maximum content reached 79.70% in the first cutting and 82.97% at the second cutting. The superior landraces were assayed
for future improvement studies. |
