In this work the Latex produced by the tree called Euphorbia Laurifola is studied through Photochemical Analysis, Infrared Spectroscopy and Mass Spectrometry. Photochemical analysis shows the presence of phenolic compounds, mainly hydrolyzable tannins. The Latex analysis by Infrared Spectroscopy confirms the results of the Photochemical analysis and determines the Infrared absorption spectrum of the Latex, a unique characteristic of an organic sample. The infrared absorption spectrum of the rubber present in the Latex studied has the best correlation with the commercial compound known as Rubber Cement. Mass spectrometry allows us to obtain data both on some molecular masses present in the Latex. As well as of the molecular structures through the analysis of possible fragments. The previous results. Allow us to deduce the molecule C61-1802, with a Benzene ring as the basic molecular structure of the Latex.
