Abstract

The seed oil of Ternstroemia gymnanthera. a species of the Ternstroemiaceae, is mainly composed of triglyceride(92.4%), followed by polar lipids(5.9%), sterol(1.2%) and pigments(0.5%). This oil contains 4.8% of cis-11, 12-methylene octadecanoic acid(lactobacillic acid) in the fatty acid composition of the total oil. This identification is based on information from non-urea inclusion formation, silver nitrate impregnated silica gel column and gas liquid chromatography, $^1H-&\;^{13}C-nuclear$ magnetic resonance and mass spectroscopy. Smaller amounts(0.1%) of presumptive 9, 10-methylene hexadecanoic acid(dihydro malvalic acid) is also detected. The major fatty acids in this oil are C18 : 1(36.1%), C18: 2(30.9%), C16: 0(15.1%), C16: 1(7.6%) and C18: 0(3.4%).

차과의 일종인 후피향의 종실유에는 틀리글리세리드가 92.4%로 대부분을 차지하고 있었으며, 소량성분으로 극성지절이 5.9%, 스테롤이 1.2%, 색소가 0.5%였다. 지방산 조성을 보면 C18 : 1(36.1%), C18 : 2(30.9%), C16 : 0(15.1%) C16 : (7.6%) 및 C18 : 0(3.4%)가 중요한 성분이었으며, 매우 흥미롭게도 cyclopropane 고리가 탄소 11, 12에 위치한 cis-11, 12-methylene octadecanoic acid가 4.8% 함유되어 있었다.
