Outline
Thirteen compounds were isolated from Armeniacae Semen Amarum using macroporous resin column chromatography combined with semipreparative high performance liquid chromatography. Their structures were identified as trans-4-O-(β-D-gentiobiosyl)-p-coumaric acid (1), trans-4-O-(β-D-gentiobiosyl) ferulic acid (2), hazelnutin F (3), amygdalinamide (4), prunasinamide (5), benzyl-β-gentiobioside (6), (S)-mandelamide (7), amygdalinic acid (8), L-phenylalanine (9), L-tryptophan (10), amygdalin (11), L-amygdalin (12), and prunasin (13) by spectroscopic methods including high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and nuclear magnetic resonance (NMR), as well as comparison with literature data. Among them, compounds 1 and 2 were identified as new compounds.
