Abstract
Perilla frutescens seeds are a good source of polyunsaturated fatty acids (PUFAs). The seeds of perilla are small end globular weight about 4 g/1000, contained approximately 35–45% oil. However the leaves are a very poor source of oil, since they contain only 0.2%. In addition, only the seed oil contains the omega 3 fatty acid alpha-linolenic acid (ALA). In comparing to other plant oils, perilla seed oil consistently contains the one of the highest proportion of omega-3 (ALA) fatty acids, at 54–64%. The omega-6 (linoleic acid) component is usually around 14% and omega-9 (Oleic acid) is also present in perilla oil. These polyunsaturated fatty acids are most beneficial to human health and in prevention of different diseases like cardiovascular disorders, cancer, inflammatory, rheumatoid arthritis etc.

Introduction
General description of Perilla frutescencs
Perilla frutescens, is a member of the Lamiaceae/Labiatae family and commonly called perilla. The crop is annual and is native to India and China. Major producing countries of perilla are China, India, Japan, Korea, Thailand, other East Asian countries. The herb is about 1 m high with small flowers, a gray-brown fruit, and glossy, downy-haired leaves. Cultivation of the crop is grown from seed and sown in May. Harvesting is usually between the end of September and beginning of October. The applicable parts of perilla plants are the leaves and seeds. There are two main types: red and green perilla. Perilla seeds, also called EBARA seed. This oil is a kind of light yellow clear and transparent liquid, with aromatic odor and slight soluble in ethanol. Major fatty acids of the oil are unsaturated fatty acids like Oleic acid 14–23%, linoleic acid 11–16%, linolenic acid 54–64% (Graph 1). This oil also contains saturated fatty acids 6.7–7.6%. Perilla seeds contain different polyphenols or flavones (rosemarinic acid, luteolin, chrysoeriol, quercetin, catcehin, apegenin and shishonin). Perilla seed oil is used as cooking oil, fuel. It is dry oil used as in paint, varnish and ink manufacturing or as a substitute for linseed oil. The seed cakes are used as animals and birds feed (Gediminas et al. 2008; Talbott and Hughes 2006; Longvah et al. 2000; Borchers et al. 1997; Narisawa et al. 1994).
