ABSTRACT
The present study was directed to determine the chemical composition of 37 woody trees at Linares, of Tamaulipas Thorn Scrub, Northeast Mexico.
The results show large variability among the species in wood chemical composition, such as neutral detergent fiber (NDF), digestible detergent fiber (ADF), lignin, cellulose, hemicellulose. In these aspects, maximum of amount NDF (94.8%) is observed in Celtis pallida, Parkinsonia aculeata, and Guaiacum angustifolium. High amount of ADF was found in three species: Celtis pallida, Parkinsonia aculeata, Lantana macropoda. With respect to lignin, Sideroxylon celastrina, Ebenopsis ebano, Ehretia anacua, Amyris texana, Leucophyllum frutescens, Cordia boissieri, and Condalia hookeri have high lignin content (over 24%). On the other hand, maximum of cellulose was observed in Parkinsonia aculeata, Celtis pallida, and Lantana macropoda have also high levels of cellulose.
130Similarly, maximum amount of cellulose was observed in Bernardia myricifolia. Close to the maximum content of hemicellulose was revealed in Celtis laevigata. With respect to fiber, maximum of fiber is observed in Celtis pallida. Close to the maximum content of fiber was found in Parkinsonia aculeata and Guaiacum angustifolium. The variations in chemical compositions could be related to quality determination and utility of timbers of different woody species.
