Methyl b-D-arabinopyranoside is a fluorine containing molecule that has been shown to be an excellent marker for suberin. It is insoluble in water, and can be detected by resonator diffraction. The chemical composition of methyl b-D-arabinopyranoside was determined using liquid crystal composition and plates. A polymer particle with a macroscopic size was used to determine the fluorescence of methyl b-D-arabinopyranoside. Fluorescence analysis showed that methyl b-D-arabinopyranoside is a green fluorescent material with a maximum emission wavelength of 514 nm. Hydroalcoholic extraction was used to isolate this compound from the plant Ricinus communis L., where it was found in constant proportions.
