摘　　要：以蜜本南瓜为材料，对其花后10～50d南瓜多糖、β-胡萝卜素、氨基酸、抗坏血酸、蛋白质、总糖、还原糖、矿质元素等营养成分含量的变化规律进行了研究。结果表明，南瓜多糖、β-胡萝卜素、氨基酸、蛋白质、总糖、还原糖含量增加，但各成分不同阶段增加幅度不同；抗坏血酸含量下降，但在果实生长发育的最后阶段又稍上升；矿质元素含量变化较为复杂；部分营养成分含量之间存在着一定的相关性。The change of nutrition content of Miben pumpkin was studied in 10- 50 d after flowering, including pumpkin-amylase,β-carotene, amino acid, Vitamin C, protein, gross sugar, reductive sugar, minerals etc. The result showed that the contents of pumpkin-amylase, β-carotene, amino acid, protein, gross sugar and reductive sugar increased, but the increase extent of each component was different. The content of Vitamin C decreased but it increased a little at the end of fruit development. The change of mineral content is complicated. There was a certain relationship between some nutrient components.
