Determination of the Levels of 10-HDA in Royal Jelly Preparations Using TLC-UV Spectrophotometry / 中国药房

ABSTRACT

This paper reports the determination of 10-hydroxy-trans-△~2-decenoic acid(10-HDA) levels in royal jelly preparations using TLC-UV spectrophotometry. This method was accurate, fast and simple with a CV of 12. 7%, offering a tool for drug control. It can be used in qualitative of quantitative analysis of 10-HDA in any royal jelly preparation. Thirty-nine royal jelly preparatons were determined and the results showed that 10-HDA was found only in 51. 3% of them. It seems to be necessary to work out a standard for qualitative identification and quantitative determination of 10-HDA in royal jelly prepartions.
