In this paper, two lipid fractions (A and B) were isolated from Sapindus mukorossi seed oil by preparative TLC and their fatty acid compositions were determined by GLC.
Abstract
Two lipid fractions ‘A’ and ‘B’ were isolated from Sapindus mukorossi seed oil by preparative TLC. Fraction ‘A’ (70.4%, Rf value 0.76) is a normal triglyceride and its fatty acid compositions was determined by GLC. Fraction ‘B’ (29.6%, Rf value 0.51) shows the presence of nitrogenous constituents. It develops a reddish brown colour in contact with alkali or alkoxide solution. Percentages of individual acids present in fraction ‘A’ were found to be: palmitic, 5.5; stearic, 3.2; oleic, 64.6; linoleic, 2.9; arachidic, 3.1; eicosenoic, 20.1; minor acids, 0.6. Fraction ‘A’ is composed of 0.1,3.6,29.9 and 66.4 percent trisaturated, monounsaturated-disaturated, diunsaturated-monosaturated and triunsaturated glycerides respectively. On GLC analysis, the percentages of individual acids constituting fraction ‘B’ were found to be:palmitic, 3.8; stearic, 1.5; oleic, 33.6; linoleic, 2.9; arachidic, 11.1; eicosenoic, 30.2; behenic, 2.8; docosenoic, 1.4 and two unidentified acids 7.3 and 5.4. Fraction ‘B’ responded to hydrolysis by pancreatic lipase and the product with polarity equivalent to that of 2-mono-glyceride was isolated by TLC and converted to methyl ester. Percentages of individual acids constituting that methyl esters were found to be:palmitic, 11.8; stearic, 4.1; oleic, 12.8; linoleic, 3.7; arachidic, 8.3; eicosenoic, 10.2; behenic, 6.5; docosenoic, 4.2; and two unidentified acids 22.2 and 16.2. This non-glyceridic component of the S. mukorossi seed oil is a cyanolipid, 1-cyano-2-hydroxymethyl prop-1-ene-3-ol. The structure was confirmed by I. R., N.M.R. and Mass spectral-analysis. Chemische Untersuchungen des Saatols Sapindus mukorossi Zwei Lipidfraktionen ‚A’ und ‚B’ wurden durch praparative DC aus dem Saatol Sapindus mukorossi isoliert. Fraktion ‚A’ (70.4%, Rf-Wert 0.76) ist ein normales Triglycerid. Seine Fettsaure-Zusammensetzung wurde durch GC bestimmt. Fraktion ‚B’ (29.6%, Rf-Wert 0.51) zeigt die Gegenwart von stickstoffhaltigen Bestandteilen. Es entwickelt bei Kontakt mit Alkali oder Alkyloxidlosung eine rotlich braune Farbe. Die prozentualen Anteile in der Fraktion ‚A’ betrugen: Palmitinsaure 5.5%, Stearinsaure 3.2%, Olsaure 64.6%, Linolsaure 2.9%, Arachidonsaure 3.1%, Eicosensaure 20.1%, andere Sauren 0.6%, Fraktion ‚A’ ist aus jeweils 0.1,3.6,29.9 und 66.4% dreifachgesattigten, einfachungesattigt-zweifachgesattigten, zweifachungesattigt-einfachgesattigten und dreifachungesattigten Glyceriden zusammengesetzt. Durch GC-Analyse wurde der prozentuale Anteil der einzelnen Sauren, aus denen Fraktion ‚B’ besteht, wie folgt ermittelt: Palmitinsaure 3.8%, Stearinsaure 1.5%, Olsaure 33.6%, Linolsaure 2.9%, Arachidonsaure 11.1%, Eicosensaure 30.2%, Behensaure 2.8%, Docosensaure 1.4% und zwei unidentifizierte Sauren 7.3% und 5.4%, Fraktion ‚B’ reagiert auf Hydrolyse durch Pankreaslipase. Das Produkt mit einer gleichen Polaritat wie 2-Mono-glycerid wurde durch DC isoliert und zum Methylester umgewandelt. Die prozentualen Anteile der diesen Methylestern zugrundeliegenden Sauren betrugen: Palmitinsaure 11.8%, Stearinsaure 4.1%, Olsaure 12.8%, Linolsaure 3.7%, Arachidonsaure 8.3%, Eicosensaure 10.2%, Behensaure 6.5%, Docosensaure 4.2% und zwei unidentifizierte Sauren 22.2% und 16.2% Dieser nichtglyceridische Bestandteil von S. mukorossi Saatol ist ein Cyanolipid, 1-Cyano-2-hydroxymethylprop-1-en-3-ol. Die Struktur wurde durch IR, NMR und Massenspektroskopie bestatigt.
