Abstract:  The red carotenoid was separated into 5 peaks by HPLC with 5μm,25cm×4.6mm ODS RP-C18 column,flow phase: methanol-water(99.5:0.5 V/V),flow velocity: 0.5ml/min,sample size: 5μl,determinating wavelength 480nm,column temperature: 18℃. The 5 peaks had the same molecular weight 562 identified by ESI-MS. The results indicated that the red carotenoid could be separated into 5 isomers by RP-C18-HPLC with the conditions above.
