Chemical composition of leaves and branches of Cedrela odorata L. from two forest plantations as a source of lignocellulosic feedstock
Cedrela odorata L., known as red cedar, is one of the most economically valuable species in Mexican forestry production.

| description | Cedrela odorata L., known as red cedar, is one of the most economically valuable species in Mexican forestry production. Although timber is the main product obtained from this species, branches and leaves are generated from thinning and pruning activities, as well as sawdust from sawmilling. These materials are currently considered as waste. This study evaluated the chemical composition of the leaves, branch wood and sawdust of red cedar from samples collected in two experimental forest plantations in El Palmar, Veracruz and San Felipe Bacalar, Quintana Roo. Concentrations of total phenols, flavonoids and their capacity for scavenging free radicals were evaluated, focusing on their potential use as a lignocellulosic source for obtaining biofuels and in applications in biomedical areas. The leaves have high concentrations of extractables with maximum values of 34,78%, polysaccharides 67,11%, lignin 31,10%, reducing sugars 6,52%, phenols 211,91 mgGAE/g, flavonoids 81,05 mgCE/g, but did not show free radical scavenging activity. In contrast, the branch wood and sawdust had low extractable levels with 6,10%, polysaccharides 78,46%, lignin 32,24%, reductor sugars 8,87%, phenols 355,57 mgGAE/g, flavonoids 178,56 mgCE/g and a high capacity for free radical scavenging. Differences were found in lignocellulosic concentrations among the samples collected at the two plantations, with the highest values in those collected at Bacalar, QR. The results obtained indicate that the leaves, branch wood and sawdust are viable for obtaining carbohydrates; while the wood can be a source of phenols and flavonoids with possible therapeutic applications. |

Cedrela odorata L., conocida como cedro rojo, es una de las especies de mayor valor económico en la producción forestal de México. Aunque la madera es el producto principal que se obtiene de esta especie, se generan también residuos como ramas y hojas en los aclareos y podas, así como aserrín y costeras en el aserrío. En este trabajo se evaluó la composición química de hojas, madera de ramas y aserrín de cedro rojo, en muestras colectadas en dos plantaciones experimentales en El Palmar, Veracruz y San Felipe Bacalar, Quintana Roo, así como la concentración de fenoles totales, flavonoides y su capacidad de captación de radicales libres, enfocadas hacia valorar su potencial como fuente lignocelulósica para obtención de biocombustibles y/o hacia la aplicación en áreas biomédicas. Las hojas presentan altas concentraciones de extraíbles con valores máximos de 34,78%, polisacáridos 67,11%, lignina 33,10%, azúcares reductores 6,52%, fenoles 211,91 mgEAG/g, flavonoides 81,05 mgEC/g, pero no presentan actividad de antiradicales libres. En cambio, la madera, tanto de ramas como de aserrín, presenta bajas concentraciones de extraíbles 6,10%, polisacáridos 78,46%, lignina 32,24%, azúcares reductores 8,87%, fenoles 355,57 mgEAG/g, flavonoides 178,56mgEC/g, y alta capacidad de captación de radicales libres. Se encontraron diferencias en las concentraciones lignocelulósicas entre las muestras colectadas en las dos plantaciones, sobresaliendo las colectadas en Bacalar, Q. R. Los resultados obtenidos indican que las hojas, la madera de ramas y aserrín son viables para obtención de carbohidratos, mientras que la madera puede ser una fuente de obtención fenoles y flavonoides con posibles aplicaciones terapéuticas.
