A New Ceramide from the Florets of Carthamus tinctorius
A new ceramide, rel-(3S,4S,5S)-3-[(2S)-2-hydroxyheneicosanoylamino]-4-hydroxy-5-[(4Z)-tetradecan-4-ene]-2,3,4,5-tetrahydrofuran (1), was isolated from the florets of Carthamus tinctorius along with two compounds, 10,12-nonacosanedione (2) and apigenin-7-O-β-apiofuranosyl-6,8-di-C-β-glucopyranoside (3), for the first time. Their structures were elucidated by means of spectral techniques including MS and 1D/2D NMR.
