%X The unsaturated fatty acids, especially linolenic acid are the main embodiment of the quality of peony seed oil. But so far, in traditional cultivation area of <em>Paeonia ostii</em>, it has not been investigated whether the soil copper content affected the quality of peony seed oil. In this study, we investigated copper content in soil and the composition of the seed oil in 30 <em>P.ostii</em> cultivation areas in Anhui Province. The copper content in the soil was 18.98-298.82 mg&middot;kg<sup>-1</sup>, and the variation coefficient was 83.06%. The contents of palm acid, stearic acid, oleic acid, linoleic acid and linoleic acid were 5.62%, 1.89%, 24.59%, 29.76% and 38.13%, respectively. The variation coefficient was between 5.66 and 9.72, among which the highest one was linoleic acid. There was a significantly negative correlation between copper content and unsaturated fatty acid content, linoleic acid content, and there was no significant correlation between the content of copper and linolenic acid content. And there was a significantly positive correlation between soil copper content and leaf copper content, <em>r</em>=0.778. The cultivation of <em>P.ostii</em> for oil production should avoid the high copper content in the soil to keep the quality of peony seed oil.
