Assessment of Species Diversity, Nutritional Content, and Antioxidant Activity of Indigenous Vegetables in the Rice Noodles with Fish Curry Sauce Dish from Nakhon Si Thammarat, Thailand
Main Article Content
Abstract
This study assessed the species diversity, nutritional content, and antioxidant activity of 25 indigenous vegetables used with a traditional dish of rice noodles with fish curry sauce from Nakhon Si Thammarat, Thailand. Significant differences (p < 0.05) were found in energy, protein, fat, carbohydrate, and ash contents. Clausena cambodiana leaves had the highest energy content (448.53±34.44 kcal/100 g), while Peperomia pellucida leaves had the lowest (288.77±0.02 kcal/100 g). Parkia speciosa seeds exhibited the highest protein content (28.61±0.05 g/100 g), while Alpinia malaccensis fruits had the lowest (7.43±0.04 g/100 g). Fat content was highest in P. speciosa seeds (17.18±0.07 g/100 g) and undetectable in its peel (0.00±0.00 g/100 g). Carbohydrates content was highest in Baccaurea ramiflora fruits (82.05±0.12 g/100 g) and lowest in P. pellucida leaves (48.85±0.08 g/100 g). P. pellucida leaves also showed the highest ash content (23.84±0.01 g/100 g). Antioxidant capacity, analyzed by ORAC, FRAP, and DPPH assays, showed distinct variations depending on the plant part. Leaves and young shoots, such as those from Litsea petiolata and Anacardium occidentale, demonstrated the highest antioxidant capacity, which correlated with their high flavonoid and phenolic compound content. Spondias pinnata and Clausena cambodiana leaves also showed high ORAC and FRAP values. Fruits, including Ficus botryocarpa and Baccaurea ramiflora, had moderate antioxidant activity, while P. speciosa seeds displayed lower values. The peel of P. speciosa performed better than its seed, particularly in the FRAP and DPPH assays. Flowers, represented by Etlingera elatior, exhibited relatively low antioxidant and nutrient levels. These findings highlight the superior nutritional and antioxidant properties of leaves and young shoots, emphasizing their importance for functional food and dietary applications.
