| 摘要: |
| 以广西玉良天坑内的茎花山柚（Champereia manillana BL.）新鲜嫩叶为试材，依据各营养成分测定的国家标准，分别对其主要活性物质、氨基酸及矿质元素含量进行测定，并结合抗氧化活性对其作出综合评价。结果表明，茎花山柚作为一种地道的特色野菜，其嫩叶粗蛋白、粗纤维和粗脂肪含量分别为7.60，7.36，0.53 g/100 g，VC含量为46.7 mg/100 g，均显著高于常见蔬菜（P<0.05）；此外氨基酸总量为4.26 g/100 g，约是香椿芽的1.5倍，其中鲜味氨基酸Asp、Glu、Gly和Ala的含量分别为0.56，0.57，0.23，0.24 g/100 g，其含量占氨基酸总量的37.6%，并且具有显著高钾低钠的特征，K含量约为Na含量的8.07倍；对其嫩叶醇溶液体外抗氧化活性研究表明，其抗氧化能力约为同等浓度VC的一半，抗氧化活性较强。茎花山柚作为特色野菜，其口味鲜美，营养价值较高，可将其作为新型经济植物开发利用。 |

| Abstract: |
| The fresh and tender leaves of the Champereia manillana BL.in Yuliang tiankeng of Guangxi were used as test materials.The contents of its main active substances,amino acids and mineral elements were determined according to national standards for the determination of various nutritional components,and their antioxidant activities were evaluated comprehensively.The results showed that as an authentic featured wild vegetable,the content of crude protein,crude fiber,and crude fat in tender leaves was 7.60,7.36,0.53 g/100 g,respectively,and VC content was 46.7 mg/100 g,which were all significantly higher than those in common vegetables (P<0.05).In addition,the total amount of amino acids was 4.26 g/100 g,which was about 1.5 times that of the Toona sinensis bud.The contents of umami amino acids Asp,Glu,Gly,and Ala were 0.56,0.57,0.23 and 0.24 g/100 g,respectively,the total amount of which accounted for 37.6% of the total amino acids,and had the characteristics of significant high potassium and low sodium.K content was about 8.07 times the Na content.Studies on the in vitro antioxidant activity of Champereia manillana young leaf alcohol solution showed that its antioxidant capacity was about half of the same concentration of VC,and its antioxidant activity was strong.In summary,as a characteristic wild vegetable,the manillana has delicious taste and high nutritional value,so it can be developed and used as a new economic plant. |
