Analysis of antioxidant nutrients in green yellow vegetable juice

摘要

The present study was attempted to investigate the contents of antioxidant nutrients in green juice of Angelica keiskei, kale, carrot, celery, cucumber. All 5 green juice were found to contain antioxidant nutrients such as #beta#-carotene, vitamin E, vitamin C, Se, Cu, Mn, Zn and phenols. #beta#-carotene contents of carrot, kale, Angelica keiskei, celery and cucumber juice were 5909.0, 3285.3, 1398.4, 176.7 and 61.4 mg/100 g, respectively, #alpha#-toco-pherol contents of 5 green juices were 0.04 approx 1.41 mg/100 g. Kale juice had highest #alpha#-tocopherol and celery juice contained lowest, kale juice also contained highest vitamin C (105.1 mg/100 g) and Angelica keiskei, cucumber, celery and carrot had vitamin C contents of 31.4, 9.3, 7.5 and 5.2 mg/100 g, respectively. Angelica keiskei had highest amount of antioxidant minerals among the sample such as Cu (0.40 mg/100 g), Mn (0.5 mg/100 g), Zn (0.24 mg/100 g), Se (0.61 #mu#g/kg). Kale was the second best source of antioxidant minerals which wore Gu (0.45 mg/100 g), Mia (0.22 mg/100 g), Zn (0.24 mg/100 g), Se (0.33 #mu#g/kg). However, celery and cucumber wcrc poor in antioxidant minerals. Total phenolic contents of 5 green juices were 0.01 approx 0.05%, kale juice also had highst total phenolics among the samples.
