Abstract

Abstract: The distribution characteristics of 16 Polycyclic Aromatic Hydrocarbon(PAHs) in different fresh tea leaves of different tea cultivars in different seasons were analyzed by using HPLC. Results showed that Zhenghedabaicha has lowest concentration of 16 PAHs and lowest standard deviation between Zhenghedabai, Taoyuandaye and Xiangfeicui, the average content is 126.92 μg·kg^-1, the standard deviation is 17.59 μg·kg^-1, the concentration of 16 PAHs and standard deviation in different part of tea leaves is expressed as: the bud< the second leaf< the fourth leaf< the sixth leaf, the PAHs′ concentration in bud is 119.13 μg·kg^-1, standard deviation is 14.36 μg·kg^-1. The concentration of 16 PAHs in different seasons is expressed as autumn<spring<summer in one year. The concentration of PAHs in autumn is 112.75 μg·kg^-1, standard deviation is 11.97 μg·kg^-1, 16 PAHs in fresh tea leaves are mainly composed of 2, 3 rings, account for about 80%. The proportion of 4-6 rings PAHs is lower.

Key words: fresh tea leaves, compounds of polycyclic aromatic hydrocarbon, distribution characteristics
