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.

사람주나무 (Sapium japonicum) 종실유의 물리 화학적 특성과 구성성분을 다양한 분석법으로 구명하였다. 사람주나무의 종실유를 구성하는 지질은 중성지질이 93% 로 가장 높고 , glycolipid 가 4.9%, phospholipid가 1.3%로 나타났다. GC 분석 결과 사람주나무의 종실에는 9종의 지방산이 존재하였다. 종실유에서 지방산의 함량은 저장기간 등에 따라 약간의 차이를 보였다. 종실유 중 3종의 지질은 silica open column을 통해 분획하고, 이들의 지방산 성분을 조사하였다. 3종의 지질 중 주요 지방산은 linoleic acid와 linolenic acid로 나타났다. 채취직후의 종실유에서 지방산의 함량은 저장된 종실유의 지방산에 비해 전반적으로높았다. 이상의 결과로 보아 사람주나무의 종실유는 화장품, 세정제, 의약품 등으로의 이용이 기대된다.
