The seeds of 16 domestic plants were studied for their moisture, total lipids and fatty acid composition. Of the 16 seeds, chestnut, corn, mungbean and ginko nut yielded less than 9% by weight of total lipids compared to others that gave 20-73%. The identified fatty acids from the seed lipids ranged from lauric acid (12:0) to lignoceric acid(24:0). It was intended in this study to classify the seed lipids according to their major fatty acids: Group t-Oleic acid; Group 2-0leic acid and linoleic acid; Group 3-linoleic acid; Group 4-linolenic acid ; Group 5-erucic acid ; Group 6-ricinoleic acid. The saturated fatty acid content of mungbean (33%) was the highest among the seed lipids studied. The highest value for the P/S fatty acid ratio(10) was in perilla.
