• I have studied the chemical components, especially polyphenolic substances and caffeine in the leaves of Camellia sasanqua and C. japonica by paper-chromatographic method.<BR>As the results of the study, it was found that paper-chromatogram of C. sasanqua was very resemble to that of C. japonica while it was remarkably different from that of Thea. Only l-epicatechin was a common substance among them. However, the same kinds of flavonoids contained in the tea leaves were detected in C. sasanqua.<BR>It seemed to be the first time that the existence of caffeine in C. sasanqua and C. japonica was acknowledged by paper-chromatographic detection.
