El Huanglongbing (HLB) es una enfermedad de los cítricos que se caracteriza por causar áreas moteadas en hojas, generar frutos deformes y decolorados, semillas abortivas, causar pérdida paulatina de la producción y provocar que la muerte de los árboles infectados sea inevitable. El agente asociado a esta enfermedad es la bacteria Candidatus Liberibacter ssp., y en México es dispersada por el vector Diaphorina citri Kuwayama (Hemiptera: Liviidae). En el presente estudio, mediante el método de microextracción en fase solida (SPME) se recolectaron compuestos volátiles emitidos de brotes vegetativos (menores a 3 cm) sanos, así como de brotes infectados con Ca. L. asiaticus, de limón persa (Citrus latifolia Tanaka) y limón mexicano (Citrus aurantifolia... |

In this work lime essential oils were extracted by hydrodistillation and supercritical carbon dioxide. In the case of hydrodistillation, the parameters evaluated were extraction time and characteristics of the plant material. In supercritical extraction, the parameters evaluated were temperature, pressure, CO2 flow, extraction time and material characteristics. Considering citral content, the best results for hydrodistillation were obtained with a distillation time of 3 hours using whole peels. The best results for supercritical extraction were found using 60ºC, 90 bar, at a CO2 flow rate of 1 mL/ min for 30 minutes using milled peels. The best yields of lime oil were obtained by hydrodistillation (5.45% w/w) and supercritical extraction (7.93% w/w) for... |
