Seedlings of wheat, oat and red cabbage and flower buds of petunia were supplied with ʟ-methionine (methyl- 14 C). Cinnamic acids and anthocyanins were purified by thin layer chromatography to constant specific activity. The methylated compounds had an 16-30 fold higher activity than the non-methylated ones. By splitting with hydroiodic acid it was shown that the methyl groups of cinnamic acids and anthocyanins contained radioactivity. Therefore the O-methylgroups of both cinnamic acids and anthocyanins had arisen from the methyl group of methionine.
