播種과 收穫時期에 따른 들깨(Perilla ocymoides)의 脂肪酸 組成變化 = Studies on Effects of Sowing and Harvesting Dates on Fatty Acids Compositions of Perilla (Perilla ocymoides)

국문 초록 (Abstract)

播種 및 收穫時期에 따른 들깨의 脂肪酸 組成 變化를 要約하면 다음과 같다.
1.油脂含量은 5月30日 播種區와 10月5日 收穫區에서 가장 높았다.
2.總 脂質의 主要脂酸은 palmitic, oleic, linoleic, linolenic acid로 이中linolenic acid의 含量이 가장 많았다.
3.不飽和度 및 C?/C? 比는 播種적기인 5月30日과 10月5日이 가장 높았다.
4.結合形態別 脂質은 植物脂質의 저장形態인 triglyceride의 含量이 가장 높았으며 主要脂?은 linolenic acid였는데 播種時期가 늦어질수록 增加하는 傾向이었다.
5.本 硏究의 結果로 南部地方의 播種 및 收穫 적기는 各各 5月30日과 10月5日로 생각된다.

This experiments are carried out obtain the effects of different snowing and harvesting dates on the oil contents and fatty acids compositions of perlla cultivar.
Total lipid was extracted from perilla seed with diethylether and sepsarated into glycolipid, sterylester, triglyceride, free fatty acid and phospholipid.
Fatty acids compositions of each fraction of lipid were analyzed by gas chromatography(GLC).
The results are summrized as follow:
Oil contents were the highest at snowing treatment on May 30 and harvesting treatment on Oct, 5.
Main fatty acid Compositions of total lipid were palmitic, oleic, linoleic and linolenic acid.
Linolenic acid was the highest.
Ratio of UFA/SFA and C?/C? were the highest at sowing date May 30 and harvesting date Oct.5.
Trglyceride was predominant composition of total lipid and main fatty acid was linolenic acid as snowing dates delayed, its contents decreased.
As a result of study, an opportunity of sowing and harvesting dates were regarded as on May 30 andOct. 5 in Southern District.
