Abstract: Fette und Seifen 563 griin. S a 1 k o w s k i sche Reaktion: Schwefelsaureschicht braungelb, Chloroformschicht farblos. Nach einiger Zeit Schwefelsaureschicht rot, Chloroformschicht farblos. 3,982 mg Sbst.. 12,205 mg CO, und 3,630 mg H,O. Eiiie Probe des Parkeols wurde auf einem Uhr glas mit einigen Tropfen retranitromethan belupft Die Kristalle farbten sich dabei intensiv gelb Parkeol-diyitonid 10 mg Parlteol wurden in 5 ccm Alkohol heili gelost und 200 mg Digitonin, in 10 ccm heigem Alkohol gelost, zugegebcn… Show more

“…The physical and chemical properties of fraction X1S4S establish it asthe straight-chain C17 saturated acid, n-heptadecanoic acid. The occurrence of nomal saturated odd-numbered fatty acids in natural fats was first established by Jantzen & Witgert (1939), who identified minute traces of nnonanoic, n-undecanoic and n-tridecanoic acids in coconut oil. Nobori (1942) later confirmed the presence of n-undecanoic and n-tridecanoic acids in coconut oil.…”
