The xanthophyll cycle components in fresh leaves of tea plant (Camellia sinensis cv. Fudingdabai)were extracted by acetone. The pigments were analyzed with a Spherisorb column （C18 , 5μm,250㎜×4.6βmm）,and were eluted using acetonitrile: methanol(85:15) and methanol:ethyl acetate(68:32) by a linear gradient. The pigments were detected by their absorbance at 445βnm. It was showed that violaxanthin, antheraxanthin and zeaxanthin from fresh leaves of tea plant were detected by HPLC, respectively, under temperatures of 15℃, 22℃ and 30℃, meanwhile, the pigments were separated well, and it is a sensitive, well-reappeared method. Tea plant had a larger xanthophyll cycle pool and a larger de-epoxidation state in higher sun-light, which indicated xanthophyll cycle plays an important role in photo-protection in tea plant.
