ABSTRACT
14 Evidence from epidemiological studies has strongly suggested that diets rich in fruits and
15 vegetables play a vital role in disease prevention. The aim of this study was to determine
16 nutrient and antioxidant content for 15 varieties of indigenous vegetables and fruits collected
17 from southern Thailand. The data indicated that indigenous vegetables provided small to
18 moderate amounts of macronutrients and minerals. The highest content of β-carotene was found
19 in Indian lettuce (Lactuca indica; 3575.54 μg/100g), whereas water dropwort (Oenanthe
20 javanica; 7439.11μg/100g) had the highest lutein content. Ripe cashew apple (Anacardium
21 occidentale; 178.34 mg/100g) and Spanish joint fir (Gnetum gnemon; 109.43 mg/100g) were
22 excellent sources of vitamin C. Mon-pu (Glochidion perakense) and young cashew leaves
2
(Anacardium occidentale) were rich sources of β-carotene, 23 lutein, total polyphenol, especially
24 gallic acid, and had relatively high ORAC and FRAP activities. In conclusion, Thai indigenous
25 vegetables provide diverse natural bioactive compounds that may contribute health benefits to
26 the consumer.
