Abstract The stem bark of Zanthoxylum rubescens has furnished two new amides identified as N-methyl, N-(3, 4-dimethoxyphenylethyl)-3′, 4′-dimethoxycinnamamide (rubemamide) and N-(3, 4-dimethoxyphenylethyl)-3, 4′-dimethoxycinnamamide (rubemamin). Two other novel amides, N-methyl, N-(3, 4-methylenedioxyphenylethyl)-3′, 4′- methylenedioxycinnamamide (dioxamide) and N-(3, 4-methylenedioxyphenylethyl)-3′, 4 ...
