Liu Ling Jin Tongming (Beijing Vegetable Research Center,Beijing 100081)
Reversed phase high pressure liquid chromatography (RP HPLC) in 454nm was used to determine the content of β carotene for 29 different carrot varieties,and the total average content was found to be 3.56mg·100g -1 .β carotene content of nantura from U.K. was the highest,6.92mg·100g -1 of U.K. varieties,2 exeeded 6.0mg·100g -1 which were 2 times of the total average. Chinese and French varieties were relatively low.The total average of 4 Chinese varieties was only 56% of that of the samples,while French B180 was the lowest,lower than 7ng·100g -1 which could not be detected by this method.
