Abstract: The isolation and HPLC detection methods of two main 5-hydroxytryptamine(5-HT) derivatives contained in safflower (Carthamus tinctorius L.) oil cake were set up.The total 5-HT derivatives were extracted from safflower oil cake by alcohol. Two compounds were isolated and purified by macroporus resin and C18 columns and identified by HPLC-MS, 1H-NMR and 13C-NMR. The results showed that purity of N-feruloylserotonin(S1) and 1N-(p-coumaroyl)serotonin separately were 96.76% and 90.29% assayed by HPLC-PDA.

Key words: safflower, N-feruloylserotonin, N-(p-coumaroyl)serotonin, HPLC-MS, NMR
