摘　　要：对米邦塔仙人掌的营养成分、活性成分分析。结果表明：粗蛋白含量为0．65％～0．68％，脂肪含量为0．30％～0．31％；氨基酸总量为6．81％～7．38％，其中谷氨酸含量达1．08％～1.52％；果胶、膳食纤维分别为1．47％～1．68％和0．87％～1．22％；干样的钙含量可达5．6％，铁8．06mg／100g，锌3．30mg／100g；B族维生素丰富，其中干样VB6含量可达5．62mg／100g；单宁0．02％～0．04％；不舍草酸；生理活性物质如粗多糖、多酚、黄酮类物质分别约为1．27％、0．063％、0．036％，半乳糖约占多糖中单糖总量的80％。在不同生长期，米邦塔仙人掌矿物质、果胶、纤维素的含量逐月增长，6个月生长期的有机酸、氨基氮、单宁的含量低，而黄酮、多酚的含量高，其他营养活性成分的差异较小。Nutritional components and bioaetive components of edible Opuntia Milpa Aha were analyzed. The results showed that the content of crude protein and fat were 0. 65%～0.68% and 0. 30%～0.31% respectively. The total content of the amino acids was 6.81%～7.38%, and Glu was 1.08%～1.52%. The contents of pectin and cellulose were 1.47%～1.68% , 0. 87% ～ 1.22% respectively. They are oxalate free and rich in Ca 5.6%, Fe 8.06 mg/100g, Zn 3.30 mg/100g, Vp,6 5.62 mg/100 g,low in tannin 0. 02% ～0. 04%. The bioaetive matter content such as polysaccharide, polyphenol, and flavone is high, about 1.27%, 0. 063% , 0. 036% respectively. 80% monosaeeharide is galaetose. In different period of growth, the content of mineral elements, pectin and cellulose increase month by month, the organic acids, amino nitrogen and tannin are low in 6 months of growth, and that polyphenol, flavone are high at that period of growth, and other nutrient components have little difference.
