잣기름을 TLC에 의하여 트리 - 글리세리드를 분리하고, HPLC에 의하여 PN별(別)로 트리 - 글러세리드를 분획(分劃)하여 분취(分取)하였다. 분취(分取)한 각획분(各劃分)을 GLC 에 의하여 아실탄소수별(炭素數別)로 재분획(再分劃)하는 한편, 각획분(各劃分)의 지방산조성(脂肪酸組成)을 분석(分析)하였다. 주요(主要) 트리 - 글리세리드를 들면 다음과 같다. $(C_{18:2},;C_{18:2},;C_{18:3},;34.9%)$, $(C_{18:1},;C_{18:2},;C_{18:3};;;10.8%)$, $(C_{18:1},;C_{18:1},;C_{18:2};;;9.9%)$, $(C_{18:1},;C_{18:1},;C_{18:1};;;6.5%)$, $(C_{18:1},;C_{18:1},;C_{18:2};;;6.3%)$, $(C_{18:1},;C_{18:1},;C_{18:3};;;4.8%)$, $(C_{16:0},;C_{18:2},;C_{18:3};;;3.3%)$, $(C_{18:0},;C_{18:1},;C_{18:2};;;2.7%)$, $(C_{16:0},;C_{18:1},;C_{18:2};;;2.6%)$, $(C_{16:0},;C_{18:2},;C_{18:2};;;2.2%)$, $(C_{16:0},;C_{18:1},;C_{18:3};;;1.9%)$, $(C_{16:0},;C_{18:2},;C_{18:2};;;1.7%)$, $(C_{16:0},;C_{18:1},;C_{18:1};;;1.7%)$, $(C_{18:1},;C_{18:3},;C_{18:3};;;1.5%)$.
The present study was directed to define the triglyceride composition of pine nut oil. The triglycerides were separated from pine nut oil by thin layer chromatography, and fractionated by high performance liquid chromatography on the basis of partition numbers. Each of these collected fractions were fractionated again by gas liquid chromatography (GLC) according to the acyl carbon number of the triglyceride, and fatty acid composition of the triglyceride was also analyzed by GLC. The pine nut oil consisted of thirty two kinds of triglycerides, and the major triglycerides of pine nut oil were those of $(C_{18:2},;C_{18:2},;C_{18:3};;;34.9%)$, $(C_{18:1},;C_{18:2},;C_{18:3};;;10.8%)$, $(C_{18:1},;C_{18:1},;C_{18:2};;;9.9%)$, $(C_{18:1},;C_{18:1},;C_{18:1};;;6.5%)$, $(C_{18:1},;C_{18:1},;C_{18:2};;;6.3%)$, $(C_{18:1},;C_{18:1},;C_{18:3};;;4.8%)$, $(C_{16:0},;C_{18:2},;C_{18:3};;;3.3%)$, $(C_{18:0},;C_{18:1},;C_{18:2};;;2.7%)$, $(C_{16:0},;C_{18:1},;C_{18:2};;;2.6%)$, $(C_{16:0},;C_{18:2},;C_{18:2};;;2.2%)$, $(C_{16:0},;C_{18:1},;C_{18:3};;;1.9%)$, $(C_{16:0},;C_{18:2},;C_{18:2};;;1.7%)$, $(C_{16:0},;C_{18:1},;C_{18:1};;;1.7%)$, $(C_{18:1},;C_{18:3},;C_{18:3};;;1.5%)$.
