Psidium guajava L. (Myrtaceae) is a native plant of Central America and is now widely cultivated in many tropical regions of the world for the fruit production. In Mexico, in the guava orchards common practices to control fruit production are: water stress, defoliation and pruning. In this study, we report the chemical composition of the biomass (branches and leaves) generated in the pruning practices. The results ranged as follows: pH (4.98-5.88), soda solubility (39.01-70.49%), ash (1.87-8.20%); potassium and calcium were the major inorganic elements in ash. No heavy metals were detected in the studied samples; total solubility (15.21-46.60%), Runkel lignin (17.77-35.26%), holocellulose (26.56 -69.49%), α-cellulose (15.53-35.36%), hemicelluloses (11.02-34.12%), tannins in aqueous extracts (3.81-9.06%), and tannins in ethanolic extracts (3.42-15.24%).
