山楂果实中水溶性维生素和可溶性游离糖的分析测定

Analysis and Determination of Water-Soluble Vitamins and Soluble free Sugars in Hawthorn Fruits

采用HPLC法,分析测定了山楂原种(Crataegus pinnatifida Bge.)的8个单株、山里红(C.pinnatifida Bge.var.major N.E.Br.)和伏山楂(C.praecox Dai. & Fu.)果实中水溶性维生素和可溶性游离糖。结果测得5种水溶性维生素和4种可溶性游离糖。山楂原种维生素C含量很高,平均为142.25mg/100g,鲜果在所有被测山楂果实中均含有较重要的游离糖—山梨糖。
