Abstract

The leaves of "saluyot" Corchorus olitorius Linne (Fam. Tiliaceae) were extracted with boiling water and the resulting mucilage was characterized. The relative viscosity of a 1.0% solution of the mucilage was determined to be 20 cps at room temperature. The mode of gelling was demonstrated through calcium ions. The results of the identification tests revealed the resemblance of mucilage with commercially available pectin. The degree of esterification and percent anhydrogalacturonides were computed to be 49.44% and 74.31%, respectively, classifying it as a low methoxy pectin. Molecular weights were approximated to be 1700 g/mole for the "saluyot" mucilage and 800 g/mole for the reference pectin sample. FTIR spectra of the saluyot mucilage and the reference pectin sample were comparable.
