目的分析我国各地区常见食物样品中白藜芦醇及其衍生物的含量。方法采集华南、华北、华西及华中四地区常见蔬菜水果前处理后,用HPLC方法分析样品中的白藜芦醇及白藜芦醇苷含量。结果华西地区的芹菜白藜芦醇总量最高,总量约7.85 g/g。不同地区的同一种食物中白藜芦醇及白藜芦醇苷含量不同,同一地区的同一类蔬果中白藜芦醇及白藜芦醇苷含量也有差异,但其含量无明显的地区及种类特异性。白藜芦醇苷是蔬菜水果中的主要存在形式,且其含量多高于白藜芦醇。结论蔬菜瓜果是居民摄入白藜芦醇及白藜芦醇苷的主要食物来源,含量以红提皮和芹菜最高。
Objective To analyze the contents of resveratrol and its derivatives in common food samples in various regions of China. Methods Pretreatment of common fruits and vegetables in South China, North China, West China and Central China was conducted. The contents of resveratrol and polydatin in the samples were analyzed by HPLC. As a result, the total amount of resveratrol in celery was the highest in West China with a total amount of about 7.85 g / g. Different regions of the same food resveratrol and polydatin levels, with the same region of the same type of fruits and vegetables resveratrol and polydatin levels are also different, but its content was not significantly different regions and species Specificity. Polydatin is the main form of fruits and vegetables, and its content higher than resveratrol. Conclusion Vegetables and fruits are the main source of food for inhalation of resveratrol and polydatin, and the contents are the highest in red extract and celery.
