Abstract: In this experiment, the leaves of Vitis vinifera L.cv.Cabernet Sauvignon were used as materials, and the effect of Ultraviolet-C on the concentration of total phenol, total flavonoids, and the flavanols were studied.The results showed that the concentration of total phenol, flavonoids, and flavanols in the leaves was higher than the control.Compared to CK, the concentration of total phenol, flavonoid, and flavanols in the leaves treated with UV-C were increased by 2.39%, 5.75%, 33.16%;1.47%, 8.74%, 18.50%;1.53%, 10.03%, 8.98%;1.23%, 7.04%, 5.13% and 0.86%, 3.31%, 0.73% at 2, 4, 6, 8, 10 h, respectively.The result of variance analysis indicated that the difference of total phenols at 2 h reached the significance level, the difference of total flavonoids at 6 h was not up to the level of the significance, the difference of flavanols at 2, 4 h reached the significant level.

Key words: Grape leaves, UV-C radiation, Total polyphenols, Total flavonoids, Flavanols
