한국산(韓國産) 식물식용유지(植物食用油脂)의 성분(成分)에 관(關)한 연구(硏究) -제2보(第2報) : HPLC에 의(依)한 면실(綿實), 대두(大豆), 호마(胡麻), 소마(蘇麻), 옥배(玉胚) 및 채종유(菜種油)의 Triglyceride 조성(組成)에 관(關)하여-

Triglyceride compositions of cottonseed, soybean, sesame, perilla corn and rapeseed oils have been determined by a high performance liquid chromatographic analysis. An optimum condition was obtained by using a ALC/GPC 244 type, from Waters Association, Japan with $\mu$ Bondapak $C_{18}(1/4^{'}\times1^{'})$ column. A similar distribution pattern of triglycerides was found in cottonseed, soybean, sesame, rapeseed and corn oils. It was noted that $C_{40}$, $C_{42}$ and $C_{44}$ were the major components in these seed oils, except perilla oil. The results showed that contents $O_{40}-C_{48}$ triglyceride types in cottonseed, sesame and corn oil were within $2.23{\sim}41.24%$ and $C_{38}-C_{48}$ triglyceride types in soybean oil were within $3.01{\sim}10.02%$ and $C_{34}-C_{46}$ triglyceride types in rapeseed oil were within $2.38{\sim}28.68%$.
