Chemical Investigations on Celastrus paniculatus Seed Oil I

Fatty acid compositions of four lipid fractions of Celastrus paniculatus seed namely normal triglycerides (20.2%), polar triglycerides (44.4%), polar nonglyceridic ester (23.5%), and nonpolar nonglyceridic ester (11.9%), have been determined by gas liquid chromatography. Percentage contents of major component acids in these fractions are: palmitic, 25.1, 42.0, 12.7, 58.2; stearic, 6.7, 4.5, 15.8; oleic, 46.1, 24.8, 4.7, 14.2; linoleic, 15.4, 14.7, 10.0; and linolenic, 3.0, 13.1, 43.0, respectively. The major molecular species constituting the normal triglycerides are: palmitooleopalmitin, 6.8%; palmitooleostearin, 5.6%; palmitodiolein, 14.7; palmitooleolinolein, 7.0%; stearodiolein, 6.1%; triolein, 8.0% and dioleolinolein 7.6%. Lipolysis of the polar triglyceride indicated as high as 59.6% of saturated acids linked to the 2-position of glycerol. Chemische Untersuchungen des Saatols von Celastrus paniculatus I Mit Hilfe der Gaschromatographie wurden die Fettsaure-Zusammensetzungen von vier Lipidfraktionen der Saat von Celastrus paniculatus bestimmt, und zwar normale Triglyceride (20.2%), polare Triglyceride (44.4%), polare nichtglyceridische Ester (23.5%) und nichtpolare nichtglyceridische Ester (11.9%). Die prozentualen Gehalte der Hauptbestandteile der Sauren in diesen Fraktionen sind: Palmitinsaure 25.1, 42.0, 12.7, 58.2; Stearinsaure 6.7, 4.5, 15.8; Olsaure 46.1, 24.8, 4.7, 14.2; Linolsaure 15.4, 14.7, 10.0 und Linolensaure 3.0, 13.1, 43.0. Die Haupttriglyceride, die die normalen Triglyceride ausmachen, sind: Palmitooleopalmitin 6.8%, Palmitooleostearin 5.6%, Palmitodiolein 14.7%, Palmitooleolinolein 7.0%, Stearodiolein 6.1%, Triolein 8.0% und Dioleolinolein 7.6%. Die Lipolyse der polaren Triglyceride ergab 59.6% gesattigte Sauren, die an die 2-Position des Glycerins gebunden sind.
