들깨기름의 트리-글리세리드조성(組成)을 밝히기 위하여 TLC에 의하여 시료유(試料油)로부터 트리-글리세리드를 분리하고, 이것을 ${mu}-Bondapak;C_{18}$ column을 사용한 HPLC에 걸어 PN별(別)로 트리-글리세리드를 분획(分劃)하였으며, 각획분(各劃分)을 분취(分取)하여 GLC로 아실 탄소수별(炭素數別)로 분획(分劃)하였다. 또한 PN별(別) 획분(劃分)의 지방산조성(脂肪酸組成)을 GLC에 의하여 분석하였다. 이들 분석 결과로부터 들깨기름을 구성하는 트리-글리세리드조성(組成)을 산정(算定)하였는데 그 수(數)는 15종류이며, 그 중 주요(主要)한 트리-글리세리드 및 그 비율은 다음과 같다. 즉, $(C_{18:3},;C_{18:3},;C_{18:3},;68.0%)$, $(C_{18:2},;C_{18:3},;C_{18:3},;6.7%)$, $(C_{18:1},;C_{18:2},;C_{18:3},;5.9%)$, $(C_{16:0},;C_{18:3},;C_{18:3},;4.3%)$, $(C_{18:1},;C_{18:2},;C_{18:3},;3.8%)$, $(C_{18:1},;C_{18:1},;C_{18:3},;3.2%)$, ($C_{16:0},;C_{18:2},;C_{18:3},;2.0%)$, $(C_{18:2},;C_{18:2},;C_{18:3},;1.5%)$ 및 $(C_{16:0},;C_{18:1},;C_{18:3},;1.0%)$ 등이다.
The triglyceride composition of perilla oil was investigated by high performance liquid chromatography (HPLC) in combination with gas liquid chromatography (GLC). The triglycerides were separated from perilla oil by thin layer chromatography (TLC), and fractionated into five groups on the basis of their partition numbers by reverse phase HPLC on a column packed with ${mu}-Bondapak;C_{18}$ using methanol-chloroform mixture as a solvent. Each of these collected fractions gave one to three peaks in the GLC chromatograms according to the acyl carbon number of the triglyceride, and fatty acid composition of the triglyceride was also analyzed by GLC. The results indicate that the perilla oil consists of fifteen kinds of triglycerides, and the major triglycerides in perilla oil were as follows: 68.0% of $(C_{18:3},;C_{18:3},;C_{18:3})$, 6.7% of $(C_{18:2},;C_{18:3},;C_{18:3})$, 5.9% of $(C_{18:1},;C_{18:3},;C_{18:3})$, 4.3% of $(C_{16:0},;C_{18:3},;C_{18:3})$, 3.8% of $(C_{18:1},;C_{18:2},;C_{18:3})$, 3.2% of $(C_{18:1},;C_{18:1},;C_{18:3})$, 2.0% of $(C_{16:0},;C_{18:2},;C_{18:3})$, 1.5% of ($C_{18:2},;C_{18:2},;C_{18:3})$, 1.0% of $(C_{16:0},;C_{18:1},;C_{18:3})$.
