采用3,5-二硝基水杨酸法、2,6-二氯酚靛酚法及高效液相色谱法等方法测定了木瓜中糖、维生素C、超氧化物歧化酶(SOD)、多酚、三萜酸等的含量,结果表明:在测定的3个品种中,打通天星木瓜品种糖含量在发育过程中不断增加,成熟时总糖和还原糖含量分别达到129.03 mg/g,52.32 mg/g鲜质量;大罗老木瓜多酚含量呈下降趋势,从生长早期的133.22 mg/g鲜质量,降至成熟时的0.37 mg/g鲜质量;打通下沟木瓜品种糖、维生素C、三萜酸含量呈现上升的趋势,且营养丰富,具有较好的开发潜力.
The content of glucose, vitamin C, superoxide dismutase (SOD) in papaya was determined by 3,5-dinitrosalicylic acid method, 2,6-dichlorophenol indophenol method and high performance liquid chromatography Phenol and triterpenic acid. The results showed that in the three tested varieties, the sugar content of the star papaya variety increased continuously during the development, and the content of total sugar and reducing sugar reached 129.03 mg / g and 52.32 mg / g fresh mass; Charolai papaya polyphenol content decreased, from the early growth of the 133.22 mg / g fresh quality, down to maturity of 0.37 mg / g fresh quality; access to the next ditch papaya varieties of sugar, vitamin C, tris The content of terpene acid showed an upward trend, with rich nutrition and good development potential.
