摘　　要：目的:通过氨基酸组成及含量研究,发掘黑老虎优良特性,为黑老虎优良品种筛选奠定基础。方法:采集广西植物研究所种质资源圃、桂林龙胜、湖南通道黑老虎成熟的果实,对其果肉和果皮进行氨基酸组成成分、氨基酸总量进行分析。结果:黑老虎果肉和果皮中必需氨基酸亮氨酸(Leu)、赖氨酸(Lys)含量较高,非必需氨基酸谷氨酸(Glu)含量较高,黑老虎的果皮氨基酸总量明显高于果肉,但果肉的E/T,E/N和1973年FAO/WHO提出理想蛋白质的标准更接近,黑老虎果皮和果肉的甜味氨基酸(SAA)丝氨酸、丙氨酸2种氨基酸含量较高,黑老虎果皮的甜味氨基酸(SAA)苏氨酸、鲜味氨基酸谷氨酸(也有的称药用氨基酸)相对苹果、梨、葡萄、桃、橙含量较高。结论:黑老虎果肉、果皮均含有人体所需的氨基酸,既可以帮助人体增强免疫功能,也可以作为水果鲜食,是一种极具有开发前景的药食兼用保健水果。Objective: Through the study of amino acid composition and content, the fine characteristics of Kadsura coccinea (Lem.) A. C. Smith were explored, which laid a foundation for the selection of fine varieties of black tiger. Methods: The mature fruits of Kadsura coccinea (Lem.) A. C. Smith in Guangxi Institute of Botany, Longsheng of Guilin and Tongdao of Hunan were collected. The composition and total amount of amino acids in the pulp and pericarp were analyzed. Results: Leucine and lysine were the essential amino acids in the pulp and pericarp of Kadsura coccinea (Lem.) A. C. Smith. The total amino acid content of Kadsura coccinea (Lem.) A. C. Smith was significantly higher than that of pulp, but the E/T, E/N of pulp were closer to the standard of ideal protein proposed by FAO/WHO in 1973. The content of sweet amino acid (SAA), serine and alanine of Kadsura coccinea (Lem.) A. C. Smith pulp and pericarp were higher, The content of sweet amino acid (SAA) threonine and delicious amino acid glutamic acid (also called medicinal amino acid in Kadsura coccinea (Lem.) A. C. Smith pericarp is higher than that in apple, pear,grape, peach and orange. Conclusion: The pulp and pericarp of in Kadsura coccinea (Lem.) A. C. Smith contain amino acids needed by human body, which can not only help human body enhance immune function, but also be used as fresh fruit. It is a kind of health fruit with great development prospect for both medicine and food.
