摘要: |
采用紫外-可见分光光分度法测定裸花紫珠等7种紫珠属植物水提液中总黄酮、总酚酸的含量及清除自由基的能力。结果表明:7种植物中的总黄酮、总酚酸含量差异很大,均以红紫珠含量最高,其黄酮、总酚酸含量分别为3.75%和2.93%; 清除自由基能力与总黄酮、总酚酸含量呈正相关性,亦以红紫珠清除自由基能力最强。研究结果将为紫珠属植物资源的开发与利用提供理论基础。 |

Abstract: |
The content of total flavonoids,total phenols and antioxidant activity in aqueous extract of 7 Callicarpa species were detected with uv-visible spectrophotometric. The results showed that flavonoid and phenol contents of these Callicarpa species were significantly different and Callicarpa rubella possessed the highest contents,3.75% and 2.93%,respectively. Moreover,the results of correlation analysis indicated that there was a positive correlation between the antioxidant capacity and the content of total flavonoids and total phenols,and Callicarpa rubella also showed strongest scavenging DPPH· radical activity. This research could provide theoretical basis for the development and utilization of Callicarpa resources. |
