M. Kawase et M. Takahashi, CHEMICAL-COMPOSITION OF SPOROPOLLENIN IN MAGNOLIA-GRANDIFLORA (MAGNOLIACEAE) AND HIBISCUS-SYRIACUS (MALVACEAE), Grana, 34(4), 1995, pp. 242-245
The chemical composition of sporopollenin from pollen of Magnolia gran
diflora Linn. (Magnoliaceae) and Hibiscus syriacus Linn. (Malvaceae) w
as investigated by several spectroscopic methods, such as X-ray photoe
lectron spectroscopy (XPS), infrared spectroscopy (IR) and UV-VIS abso
rption spectroscopy (UV-VIS). The results suggest that sporopollenin c
onsists of only three kinds of element, C, H and O. We could not find
any metalic components in sporopollenin. The derail study by XPS sugge
sts that the carbon atom in sporopollenin is mainly aliphatic carbon.
The present study implies that the main structure of sporopollenin is
a simple aliphatic polymer containing aromatic or conjugated side chai
ns.
