为开发神秘果叶药理活性，对海南产神秘果叶的营养成分进行了分析，并评价其营养价值。研究结果表明，神秘果叶中粗蛋白、粗纤维和多糖含量较高。共检测出7种脂肪酸，其中3种不饱和脂肪酸占脂肪酸总量的50%，以α-亚麻酸的含量最高，达到0.25 g/100 g。矿物质元素含量丰富，在常量和微量元素分析中，分别以K和Fe的含量最高，潜在的有害元素汞、铅、镉、砷含量均低于《中国药典》（2010版）。氨基酸组成全面、种类齐全，8种必须氨基酸含量占总氨基酸总量的41.50%。因此，神秘果叶是营养价值较高的新资源食品，具有很好的开发前景。%The nutritional compositions of Synsepalum dulcificum (S. dulcificum) leaf were analyzed to exploit the pharmacological activity in local tropical plant from Hainan, along with evaluating the nutritional value of S. dulcificum leaf. The results indicated that S. dulcificum leaf was rich in crude protein, crude fiber and polysaccharide. Meanwhile, 7 fatty acids were identified from the S. dulcificum leaf, including 3 unsaturated fatty acids with a relative content 50 %, and the higher content of these unsaturated fatty was α-linolenic acid, reached 0.25 g/100 g. Moreover, the contents of K and Fe in the tested mineral elements were higher as a relatively abundant macro element and micro element, respectively. The content of potentially toxic micro elements, including Pb, Cd, Hg and As were less than the maximum levels according to Chinese Pharmacopeia (2010). Furthermore, it contained a full range of amino acid, and the 8 essential amino acids accounted for 41.50%of the total amino acids. On the basis of these analyses, it can be concluded that S. dulcificum leaf is an excellent new food resource with a fundamental nutrition value for further research and exploitation.
