Abstract

Carotenoid composition of green leafy vegetables (GLVs, n=30) with medicinal value was analyzed by HPLC; vitamin A activity (as retinol equivalent, RE) of provitamin A carotenoids was calculated. Results show that among GLVs studied, the level of beta-carotene (50-130mg/100g dry wt) was higher in nine GLVs than other carotenoids while lutein (50-187mg/100g dry wt) and zeaxanthin (1-5mg/100g dry wt) were higher in 12 GLVs than other xanthophylls. alpha-Carotene was detected only in nine GLVs, ranging from 1 to 37mg/100g dry wt. Interestingly, Chenopodium album, Commelina benghalensis and Solanum nigrum were found to contain higher levels of both lutein and beta-carotene in the range of 84-187 and 50-115mg/100g dry wt, respectively. The values of retinol equivalents (RE) ranged from 641 to 19101 and were higher (>10,000) in six GLVs of the 30. The results demonstrate that GLVs studied contained higher levels of RE and lutein.
