| 通过研究蔬菜营养成分及自由基清除能力，揭示不同蔬菜营养价值差异，为指导大众日常饮食
健康奠定理论基础。以深圳市7 种常见叶菜类蔬菜为材料，测定其9 种营养成分含量及蔬菜汁对DPPH 和
ABTS 自由基的清除活性。结果表明，番薯叶含有极高的总酚、总黄酮和较高的膳食纤维，使其自由基清除
能力明显强于其他蔬菜。上海青、菠菜和小白菜次之。而麦菜和生菜由于极低的生物活性物质含量，导致其
综合评价最低。相关分析结果显示，蔬菜汁自由基清除能力与其总酚、总黄酮含量存在显著性强相关，其次
为膳食纤维和色素，而维生素C 与自由基清除能力相关性偏弱。本次测试蔬菜中番薯叶和上海青营养价值
最高，其次为菠菜、菜心和小白菜，最后为麦菜和生菜。 |

| In order to reveal the differences of nutritional value od different vegetables，and guide people
daily diet healthy，the vegetable nutritional components and free radical scavenging ability were studied. In this
experiment，7 kinds of common leafy vegetables sold in Shenzhen were used as materials，nine kinds of nutrient
contents and scavenging activity of vegetable juice on DPPH and ABTS were determined. The results showed that
the Ipomoea batatas（ L.） Lam contained extremely high content of total phenol，total flavonoid and higher dietary
fiber content，had the strongest free radical scavenging activity，followed by Brassica campestris L. ssp. chinensis
（L.） Makino，Spinacia oleracea L. and B. chinensis L. While Lactuca sativa var longifoliaf. Lam and L. sativa L.
var. ramosa Hort. had the lowest nutritional value，due to very low levels of bioactive substances. The correlation
coefficient analysis showed that the free radical scavenging ability of vegetable juice was positively correlated with the
content of total phenol and total flavonoid，then dietary fiber and pigment. However，the correlation between vitamin
C and free radical scavenging capacity was weak. The comprehensive analysis indicated that the nutritional value of
I. batatas（ L.） Lam and B. campestris L. ssp. chinensis（ L.） Makino was the highest，followed by S. oleracea L.，B.
parachinensis Bailey. and B. chinensis L.，and finally for L. sativa var longifoliaf. Lam and L. sativa L. var. ramosa
Hort. |
