Resumen


Se estudió el efecto de varios métodos de secado (planta fresca, secado a la sombra, secado al sol y secado en horno a 30 y 60 °C) sobre la composición del aceite esencial (AE) de geranio con aroma a rosas. Los aceites esenciales de las muestras fueron extraídos por hidrodestilación y analizados mediante GC y GC-MS. Los mayores contenidos de AE los obtuvo la planta fresca (1,98%), seguido del secado a la sombra (1,34 %) y secado en estufa a 30 °C (1,20 %). Los principales componentes fueron citronelol (23,99-39,87 %), geraniol (4,15-17,09 %), mentona (4,48-8,34 %), linalol (1,96-7,42 %), β-cariofileno (2,63-4,32 %), geranil tiglato (0,99-4,52 %), butirato de citronelilo (0,53-5,31 %) y óxido de cis-rosa (0,71-3,15 %), los métodos de secado mostraron un marcado impacto en los constituyentes de las muestras de EO. Los resultados demostraron que el secado de las partes aéreas del geranio fresco, y el secado a la sombra y el secado en horno a 30 °C fueron los mejores métodos óptimos para obtener el mayor rendimiento de aceite y contenido de citronelol, geraniol y linalool en el aceite.
