This paper investigates the total polyphenolic and flavonoid content as well as the antioxidant activity of Ziziphora clinopodioides Lam. extracts of different polarity.
The total polyphenolic content was analysed using the Folin-Ciocalteu method. Total flavonoid content analysis was performed using the colorimetric method.
The total polyphenolic content of Z. clinopodioides is concentrated in parts of ethyl acetate (19.27%), chloroform (4.99%) and n-butanol extracts (3.94%) containing a small amount of the total polyphenolic content. The petroleum ether (0.23%) and ethanol extracts (1.64%) contain almost no polyphenolic content. The total flavonoid content of Z. clinopodioides is concentrated in parts of ethyl acetate (65.61%), chloroform (14.36%) and n-butanol extracts (10.76%) containing a small amount of the total polyphenolic content. The Z. clinopodioides Lam. ethyl acetate extract exhibits a good antioxidant activity.
Ethyl acetate extracts contain a large number of polyphenolic compounds (19.27%) and flavonoids (65.61%) owing to good antioxidant capacity.
本文研究了不同极性的斜生紫堇提取物的总多酚和黄酮含量以及抗氧化活性。
采用福林-酚法分析总多酚含量。采用比色法进行总黄酮含量分析。
斜生紫堇的总多酚含量集中在乙酸乙酯部分（19.27%）、氯仿部分（4.99%）和正丁醇提取物（3.94%），其中总多酚含量较少。石油醚部分（0.23%）和乙醇提取物（1.64%）几乎不含多酚。斜生紫堇的总黄酮含量集中在乙酸乙酯部分（65.61%）、氯仿部分（14.36%）和正丁醇提取物（10.76%），其中总多酚含量较少。斜生紫堇乙酸乙酯提取物具有良好的抗氧化活性。
乙酸乙酯提取物由于具有良好的抗氧化能力，含有大量的多酚化合物（19.27%）和黄酮类化合物（65.61%）。
