Produção e composição química da macela em função da época de colheita

Abstract: A macela (Egletes viscosa (L.) Less.) é uma planta herbácea, anual, de caule cespitoso, toda pilosa, glandulosa, com folhas pinatífidas, de 2-5 cm de comprimento e subpecioladas. Possui capítulos florais solitários, curtopedunculados, dispostos em corimbos axilares e terminais com invólucro largo campanulado, brácteas pilosas, lanceoladas e agudas; a corola é alvo-BEZERRA AME; MEDEIROS FILHO S; OLIVEIRA LDM; SILVEIRA ER. 2008.

“…According to Koshima et al (2006), the concentration of citral essential oil of lemongrass varied depending on plant age (6, 9, 12 and 15 months), and is produced in higher concentrations at 6 and 15 months of age. Similar results were observed by Bezerra et al (2008), who noted changes in the chemical composition of the essential oil of Egletes viscosa according to the plant age. Santos et al (2012) studied the plant age (3, 6, 9 and 12 months) on the chemical composition of the essential oil of A. zerumbet and verified variations in chemical composition of this oil between six and nine months.…”

“…De fato, os metabólitos secundários representam uma interface química entre as plantas e o ambiente. Os estímulos decorrentes do ambiente, no qual a planta se encontra, podem redirecionar a rota metabólica, ocasionando a biossíntese de diferentes compostos (Bezerra et al, 2008). A composição do óleo essencial de L. alba apresenta variação quantitativa e qualitativa, levando à separação em quimiotipos (Matos, 1996;Frigheto et al, 1998;Zoghbi et al, 1998), os quais poderiam apresentar atividades farmacológicas distintas, bem como diferenças morfológicas (Matos, 1996;Correa, 1992).…”
