To investigate changes in fatty acid and lipid composition of maturing perilla (Perilla frutescens var. japonica Hara) seeds, Suweon 10 and Jeju varieties were subjected to lipid analysis. The results were summarized as follows; As perilla seeds matured, content of glycolipid and phospholipid decreased. Glycolipid and phospholipid of mature seed were 25.4% and 4.5% of total lipids in Suweon 10 and those from Jeju were 44.5%, 4.0%, respectively. Cerebroside, galatosyl diglyceride and monogalatosyl diglyceride were major constitutents of ether-extractable glycolipids in developing perilla seeds. Monogalatosyl diglyceride, the richest constitutent in the early stage of seed development, decreased rapidly as seeds matured. In ether-extractable glycolipid of mature Suweon 10 seeds, content of linolenic acid was 51.1% which was higher than 19.4% of oleic acid of total acids. However, in Jeju variety, content of oleic acid was 31% which was higher than 18.6% of linolenic acid. Phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl glycerol and lysophosphatidyl inositol were major constituents of phospholipids. Content of phosphatidyl glycerol in developing seeds showed irregular changes in Jeju but in Suweon 10, it decreased after rapid increase in the early stage of seed development. Olieic acid ranges $28.7{\sim}35.2%$, linolenic acid $8.2{\sim}11.2%$, linoleic acid $16.4{\sim}32.5%$ and Palmitic acid $22.7{\sim}29.9%$ of total fatty acids in methanol-ertractible phospholipid of mature perilla seeds.
