Physicochemical Properties and Fatty Acid Composition of Two Kinds of Perilla frutescens Seeds Oil

The oil was extracted by solvent extraction from two new cultivars of Perilla frutescens seed and the physicochemical properties and fatty acid compositions of the oils were studied.Results showed that the two kinds of oil were of good quality and the content of unsaturated fatty acid was significantly higher than saturated fatty acid.As the main constituent,the contents of α-linolenic were 62.91% and 61.57% respectively.Zhengning P.frutescens was more suitable for planting in local.
