DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) An optimized reversed-phase high-performance liq. chromatog. method was developed to detect the trans-10-hydroxy-2-decenoic acid (10-HDA) content in royal jelly cream and lyophilized powder. 14113-05-4 is the cas registry number. This chemical is also mentioned in this article. The sample was extd. using abs. ethanol. Chromatog. sepn. of 10-HDA and Me 4-hydroxybenzoate as the internal std. was performed on a Nova-pak C18 column. The av. recoveries were 95.0-99.2% (n = 5) with relative std. deviation (RSD) values of 1.3-2.1% for royal jelly cream and 98.0-100.0% (n = 5) with RSD values of 1.6-3.0% for lyophilized powder, resp. The limits of detection and quantitation were 0.5 and 1.5 mg/kg, resp., for both royal jelly cream and lyophilized powder. The method was validated for the detn. of practical royal jelly products. The concn. of 10-HDA ranged from 1.26 to 2.21% for pure royal jelly cream samples and 3.01 to 6.19% for royal jelly lyophilized powder samples. For 30 royal jelly products, the 10-HDA content varied from not detectable to 0.98%. .
