| description | Frequent anthocyanin consumption improves health and prevents diseases due to
its antioxidant activity. Exposure of some plants to high concentrations of heavy metals
may increase anthocyanin concentration and thus improve their food quality. This study
determined the effect of Cu spraying on hibiscus (Hibiscus sabdariffa L.) leaves at various
dosages and number of doses on anthocyanin content, physical and chemical characteristics,
and calyces yield. For this purpose, hibiscus genotype Reina Roja was grown
under rainfed conditions. During the vegetative stage, Cu was sprayed two, four or six
times with 150, 300 and 450 mg L-1. The results indicate that four and six sprayings
with 150, 300 and 450 mg Cu L-1 reduced dry calyces yield. Two sprayings at either
Cu dosage did not modify calyces yield. Added Cu increased significantly anthocyanin
content and titratable acidity and decreased ascorbic acid content in the calyces. Anthocyanin
content increased the most (57 and 44%) when Cu was sprayed six times at 300
and 450 mg L-1. The data suggests that two sprayings with 150 mg Cu L-1 could improve
nutritional quality of hibiscus extracts without affecting dry calyces yield. |

El consumo frecuente de antocianinas mejora la salud y previene enfermedades, debido a su actividad antioxidante. La exposición de algunas plantas a concentraciones altas de metales pesados puede incrementar la concentración de antocianinas y mejorar su calidad funcional. Este estudio determinó el efecto de la aplicación foliar de Cu en varias dosis y número de aplicaciones sobre el contenido de antocianinas, características físico-químicas y rendimiento de cálices de jamaica (Hibiscus sabdariffa L.). Para este propósito se cultivó el genotipo Reina Roja que durante la etapa vegetativa, se asperjó al follaje con Cu en dos, cuatro y seis ocasiones con 150, 300 y 450 mg L-1. Los resultados indican que cuatro y seis aplicaciones de cobre redujeron el rendimiento de cálices secos para todas las dosis. Dos aplicaciones no modificaron el rendimiento de cálices. El Cu incrementó significativamente el contenido de antocianinas, acidez titulable y disminuyó el contenido de ácido ascórbico en los cálices. Los aumentos mayores de antocianinas (57 y 44%) fueron con seis aplicaciones de 300 y 450 mg de Cu L-1. Los datos sugieren que dos aplicaciones de 150 mg de Cu L-1 pueden mejorar la calidad nutracéutica de los extractos de jamaica sin afectar el rendimiento de cálices secos.
