Fatty oil obtained from the ripe seeds of Prunus dulcis (Mill.) D.A. Webb var. dulcis or Prunus dulcis (Mill.) D.A. Webb var. amara (DC.) Buchheim or a mixture of both varieties by cold expression. It is then refined. A suitable antioxidant may be added.<\/p>\n
Pale yellow, clear liquid.<\/p>\n
Slightly soluble in ethanol (96 per cent), miscible with light petroleum.<\/p>\n
About 0.916.<\/p>\n
It solidifies at about -18 \u00b0C.<\/p>\n
A. Identification of fatty oils by thin-layer chromatography (2.3.2).<\/p>\n
Results\u00a0 The chromatogram obtained is similar to the corresponding chromatogram shown in Figure 2.3.2.-1.<\/p>\n
B. Composition of fatty acids (see Tests).<\/p>\n
0.2 to 6.0, determined at the absorption maximum at 270 nm.<\/p>\n
To 0.100 g add cyclohexane R and dilute to 10.0 mL with the same solvent. Adapt the concentration of the solution so that the absorbance lies between 0.5 and 1.5, measured in a 1 cm cell.<\/p>\n
Maximum 0.5, determined on 5.0 g.<\/p>\n
Peroxide value (2.5.5, Method A) Maximum 5.0.<\/p>\n
Maximum 0.9 per cent, determined on 5.0 g.<\/p>\n
Use the mixture of calibrating substances in Table 2.4.22.-3.<\/p>\n
