英文摘要:

      Objective To investigate the nutritional components in Rosa dianhong. Methods According to the Chinese Food Composition, the basic nutrients such as protein, crude fiber, minerals and amino acids were selected and tested by the national food safety standard methods, and compared with common vegetables to evaluate the nutritional value of the eight-street rose. Results The content of fats was 0.5 g/100 g, crude fiber was 2.5 g/100 g, carbohydrate was 12.4 g/100g in Rosa dianhong. The contents of these nutrients in Rosa dianhong were higher than in Bok choi (white), cabbage and Chinese cabbage. The minerals were rich in phosphorus and potassium, which were 46.3 mg/100 g and 243 mg/100 g, respectively. The trace elements of iron, copper and manganese are 1.02, 0.10 and 0.81 mg/100 g, respectively, which were superior to common vegetables. Rosa dianhong had no significant advantage in protein, amino acid and vitamin C content compared to common vegetables. Conclusion Rosa dianhong has high crude fiber content and rich minerals, which can be used as a dietary source for those nutrients and has good potential development value.
