This study examined the nutritional compositions of seven raw and blanched green vegetables: Amaranthus mangostanus L. (AM), Aster scaber Thunberg, Taraxacum platycarpum H. Dahlstedt (TP), Oenanthe javanica (Blume) DC, Allium tuberosum Rottler, Ligularia fischeri (Ledeb.) Turcz (LF), and Euonymus alatus (Thunb.) Siebold (EA). Proximate compositions (moisture, protein, ash, dietary fiber, and fat), minerals (calcium, phosphorus, iron, potassium, sodium, and magnesium), and vitamins (riboflavin and vitamin C) were analyzed in the study. In this study, moisture contents of raw and blanched green vegetables were 71.28~92.68 g/100 g and 76.90~92.09 g/100 g, respectively. The protein and fat contents of raw LF (33.38 g/100 g and 4.50 g/100 g dry weight basis, respectively) were higher than those of other cultivars. Ash contents of AM were significantly higher than those of their respective raw samples. Potassium, magnesium, calcium, and sodium contents of AM were 7,710.63 mg/100 g, 1,786.67 mg/100 g, 1,534.44 mg/100 g, and 743.18 mg/100 g, respectively. In the case of raw green vegetables, iron content of TP was 55.23 mg/100 g, which was the highest value among tested green vegetables. Total dietary fiber content of EA was 59.75 g/100 g, which was the highest value. Riboflavin content was highest in the raw and blanched LF (3.10 mg/100 g and 3.05 mg/100 g, respectively). Vitamin C contents of raw and blanched EA were 468.28 mg/100 g and 471.42 mg/100 g, respectively, which were higher than the other values. There were differences in nutritional ingredients according to different types of green vegetables. Therefore, it is advisable to evenly ingest various green vegetables.
