摘　　要：该研究对石榴红曲保健果醋的主要营养成分进行检测,并考察果醋的降糖、降脂及体内抗氧化活性。结果表明,该果醋营养丰富,从中共检测出17种氨基酸,总氨基酸含量为171.9 mg/100 g,其中9种(包括组氨酸)属于人体必需氨基酸,占游离氨基酸总量的49%;总黄酮、总酚、还原糖、总酸和可溶性固形物含量分别为8.25 mg/mL、20.82 mg/mL、15.74 g/100 mL、5.82 g/100 mL、18.67 g/100 mL。果醋在10.0 mL/kg的剂量下能明显降低高糖高脂小鼠的空腹血糖、总胆固醇、甘油三酯和低密度脂蛋白胆固醇含量,提高高密度脂蛋白胆固醇含量及机体胰岛素敏感指数,具有一定的降糖、降脂功能;同时,还能明显降低D-半乳糖氧化损伤小鼠血清的丙二醛含量,升高过氧化氢酶、谷胱甘肽过氧化物酶、超氧化物歧化酶活性及谷胱甘肽含量,具有体内抗氧化活性。Taking pomegranate Monascus health fruit vinegar as the research object,the main nutritional components of fruit vinegar were determined,and the hypoglycemic,lipid-lowering and antioxidant activities in vivo of fruit vinegar were investigated.The results showed that 17 kinds of amino acids were detected in the fruit vinegar,the total amino acid content was 171.9 mg/100 g,among which 9 kinds(including histidine)were essential amino acids for human body,accounting for 49%of the total free amino acids.Meanwhile,the contents of total flavonoids,total phenols,reducing sugar,total acid and soluble solids in the fruit vinegar were 8.25 mg/ml,20.82 mg/ml,15.74 g/100 ml,5.82 g/100 ml,and 18.67 g/100 ml,respectively.The fruit vinegar reduced the content of fasting blood glucose,total cholesterol,triglyceride and low density lipoprotein cholesterol of high-glucose and high-fat mice,increased the content of high-density lipoprotein cholesterol and the insulin sensitivity index of mice at the dose of 10.0 ml/kg,which had certain hypoglycemic and lipid-lowering functions.At the same time,it could significantly decrease the content of malonaldehyde in serum of mice injured by D-galactose oxidation,and increase the activity of catlase,glutathione peroxidase,superoxide dismutase,and glutathione,which had antioxidant activity in vitro.
