ABSTRACT
Two new phenylpropanoid amide glycosides and ten analogues were isolated from the CH_2Cl_2 layer of 95% ethanol extract of the whole plants of Corydalis racemosa by using various chromatographic techniques, including silica gel, Sephadex LH-20, ODS column chromatographies, and semi-preparative HPLC. Their structures were identified on the basis of physicochemical properties, MS, NMR, and IR spectroscopic data as N-cis-sinapoyltyramine-4'-O-β-glucoside(1), N-cis-sinapoyl-3-methoxytyramine-4'-O-β-glucoside(2), N-cis-sinapoyltyramine(3), N-cis-feruloyltyramine(4), N-trans-cinnamoyltyramine(5), N-trans-feruloylphenethylamine(6), N-trans-p-methoxycinnamoyl-3-hydoxyoctopamine(7), N-cis-feruloyl-3-methoxytyramine(8), N-trans-feruloyltyramine(9), N-trans-feruloyl-3-methoxytyramine(10), N-trans-sinapoyltyramine(11), and N-trans-p-coumaroyltyramine(12). Compounds 1 and 2 are new compounds. Compounds 3-7 are obtained from the plants of Papaveraceae for the first time, and compounds 8-12 are firstly isolated from C. racemosa.
