Abstract
Free and bound lipids of both inner and outer part in the edible portion of 3 varieties of chestnuts(Castanea crenata) were extracted and fractionated into neutral lipid, glycolipid and phospholipid, by silicic acid column chromatography. Fatty acid composition of each fraction was examined with gas chromatography. Lipid contents in chestnut on dry weight basis were 1.84% in inner part(1.26%-free lipid and 0. 58% bound lipid) and 1.95% in outer part (1.63%-free lipid and 0.32%-bound lipid). Free lipid content was
은기(銀寄), 녹조(鹿鳥), 상피(霜被)의 3가지 밤 품종(品種)을 시료(試料)로 하여 과육(果肉)을 내과육(內果肉)과 외과육(外果肉)으로 나눈 후에 유리지질(遊離脂質) 및 결합지질(結合脂質)을 추출(抽出) 하고 그의 지질조성(脂質組成) 및 구성지방산(構成脂肪酸)을 column chromatography, gas chromatography에 의하여 분리(分離), 정량(定量)하였다. 밤의 총지질(總脂質)의 평균함량(고형물당(固刑物當))은 내과육(內果肉)에 1.84%, 외과육(外果肉)에 1.95%였으며 이 중에서 유리지질(遊離脂質)은 내과육(內果肉)에 1.26%, 외과육(外果肉)에 1.63%이나 결합지질(結合脂質)은 내과육(內果肉)에 0.58%, 외과육(外果肉)에 0.32%로서 유리지질이 결합 지질보다
