answer:Well, do you know how much of that is water content? If so, you could use this information: “The mean contents in dry weight (DW) in different carrot preparations ranged from 406.7 to 456.3, from 183.7 to 213.5 and from 29.0 to 39.6 microg/g for beta-carotene, alpha-carotene and lutein.” You might want to note that carrots are not a particularly rich source of lutein although they are high, not surprisingly, in carotenoids.
