Analysis on nutrient components of seed kernel of Eurycorymbus cavaleriei

无患子科（Sapindaceae）伞花木属（Eurycorymbus Hand.-Mazz.）单科单属植物伞花木〔Eurycorymbus cavaleriei（Lévl.）Rehd.et Hand.-Mazz.〕为中国特有种,分布于湖南、江西、广东、广西、云南、贵州、福建和台湾等省（区）[1],为国家Ⅱ级重点保护野生植物[2]。

Contents of protein and total sugar, composition and content of amino acids, and contents of K, P, Mg, Ca, Fe, Zn, Mn, Cu, Na, Hg, Pb and Cd in seed kernel of Eurycorymbus cavaleriei （L6vl.） Rehd. et Hand.-Mazz. were analyzed. The results show that contents of protein and total sugar are 25.10% and 3.80% , respectively. Content of total amino acids is 208.70 g · kg-1 , in which, content of seven essential amino acids accounts for 36.03% of content of total amino acids. In mineral elements, content of K is the highest （8.89×103 mg· kg-1） ; contents of P, Mg and Ca are also relatively high （3.70×103, 3.14×103 and 1.78×103 mg · kg-1 , respectively） , while contents of harmful elements Hg, Pb and Cd are low. Overall, contents of protein, amino acids and mineral elements in seed kernel of E. cavaleriei are rich, so its nutritional value is relatively high.
