TELLEZ-SANCHEZ, C.; OCHOA-RUIZ, H. G.; SANJUAN-DUENAS, R. y RUTIAGA-QUINONES, J. G.. Chemical components of heartwood in Andira inermis (W. Wright) DC. (Leguminosae). Rev. Chapingo ser. cienc. for. ambient [online]. 2010, vol.16, n.1, pp.87-93. ISSN 2007-4018. https://doi.org/10.5154/r.rchscfa.2099.11.046.
A chemical analysis was performed on the heartwood of Andira inermis to identify its main chemical components. The results found were: pH 5.9, 0.71% inorganic substances, 19.1 % extractives, 34.2 % lignin and 65.78 % polysaccharides. In ash, the following components were detected: calcium, magnesium, sulfur and silicon. To obtain the extractives content, the heartwood meal was subjected to sequential extraction with cyclohexane, chloroform, acetone and methanol in Soxhlet equipment and later in hot water under reflux. Heartwood solubility was higher in acetone (8.6 %) and methanol (5.3 %), and the total content of extractives was 19.1 %.
