Yield and composition of the essential oil of Mentha piperita L. (Lamiaceae) grown with biosolid Braz. J. Plant Physiol.
Scavroni,Joseane; Boaro,Carmen Sílvia Fernandes; Marques,Márcia Ortiz Mayo; Ferreira,Leonardo Cesar.
This research evaluated the effects of biosolid levels on yield and chemical composition of Mentha piperita L. essential oil. Mint plants were grown in a greenhouse in pots containing the equivalent to 0, 28, 56, and 112 t.ha-1 biosolid. Three evaluations were made at 90, 110, and 120 days after planting (DAP). The oil was extracted from the dry matter of shoots by hydrodistillation, and composition was determined by GC/MS. Oil production was slightly affected by the biosolid, increasing when plants were grown with 28 t.ha-1, a condition which did not result in quality improvement. Menthyl acetate was the component obtained at the highest percentage in all treatments. At 90 DAP, plants showed a higher percentage of menthol, the second-highest oil...
