The provitamin A contents of 16 vegetables grown in Taiwan were analyzed by high-performance liquid chromatography with photodiode-array detection. The amounts of the major provitamin A compounds, beta-cryptoxanthin, alpha-carotene, and beta-carotene ranged from 0-6.8, 0-27.7, and 0.6-104.9 micrograms/g, respectively. The highest beta-carotene content was found in basil, followed by onion fragrant, kale, carrot, spinach, water convolvulus, mustard, green onion, garland chrysanthemum, sweet potato, green pepper, yellow corn, mustard stem, lettuce, cabbage, and celeriac. Carrot was the only vegetable found to contain alpha-carotene while corn was the vegetable to contain beta-cryptoxanthin.
