A total of 37 varieties of fresh fruits obtained from six representative markets in Bangkok, Thailand, were
determined for their beta-carotene, lycopene, and alpha-tocopherol contents using high performance
liquid chromatography. Beta-carotene content ranged from undetectable up to 616 lg/100 g of edible
portion, lycopene content from undetectable up to 6693 lg/100 g and vitamin E content from not undetectable
up to 1.43 mg/100 g. Red watermelon, Citruluss vulgalis (‘‘jin-trarah” variety) was the richest
source of dietary beta-carotene (1040 lg/serving) and lycopene (11,378 lg/serving), whilst the highest
alpha-tocopherol content was found in unripe mango, Mangifera indica (‘‘keosawoei” variety) with
approximately 0.90 mg/75 g of edible portion, providing 9% of the Thai recommended daily intake of vitamin
E.
