摘要
为探讨陀螺果叶片的进一步开发利用,以来自4个不同种源地A(江西齐云山)、B(四川峨眉山)、C(湖北咸宁)、D(广东乳源)陀螺果的叶片为试验材料,测定叶片的含水量、叶绿素、蛋白质、可溶性糖、维生素C 5种基本营养成分以及重金属含量。结果表明,叶片含水量表现为C>B>A>D,叶绿素含量为B>A>C>D,蛋白质含量为D>A>C>B,可溶性糖含量为A>B>D>C,维生素C含量为C>D>B>A;重金属含量中,As的含量相对略高,Cr、Cu、Zn、Cd、Sb的含量均较低,但均符合国家食用标准范围内。
In order to explore the further development and utilization of M.xylocarpum leaves,the leaves of M.xylocarpum from four different provenances in A(Mount Qiyun of Jiangxi Province),B(Mount Emei of Sichuan Province),C(Xianning,Hubei Province)and D(Ruyuan,Guangdong Province)were taken as the experimental materials to measure the basic nutritional elements such as the leaf water content,chloro-phyll content,protein content,soluble sugar content,vitamin C content,and the contents of heavy metal differences were analyzed.The results showed that the leaf water content of the four provenances was C>B>A>D,the chlorophyll content was B>A>C>D,the protein content was D>A>C>B,the contents of soluble sugar were A>B>D>C,and the content of vitamin C was C>D>B>A.Among the heavy metal content,the content of As was relatively high,and the content of Cr,Cu,Zn,Cd and Sb were all low,but all met the national edible stand-ards.
