Abstract

|
Physico-chemical characteristics and chemical composition of seed oil of Sapium japonicum were determined by various analysis methods. Physio-chemical characteristics of the extracted oil from fresh seed were specific gravity (0.928), refraction index (1.477), acid value (2.30), saponification number (190.0), and iodine value (126.0). Neutral lipid (93%) in seed oil was identified as major components, followed by glycolipid (4.9%) and phospholipid (1.3%). In GC analysis, nine fatty acids were presented in the seed oil. Among fatty acids, predominant fatty acids were oleic acid (45.8%) and linoleic acid (35.6%). The contents of fatty acids of seed oil somewhat varied with their storage period. Composition of fatty acids from lipid fractions which were isolated on silica open column was investigated. Major fatty acids in three lipid fractions were linoleic acid and linolenic acid. The fatty acid contents of fresh seed oil derived from each lipid fraction were generally high comapred to storage seed oil. From the above results, seed oil of Sapium Japonicum could be useful in cosmetics, detergents and a few pharmaceuticals.
