Antibacterial Mechanism of 10-HDA Against Bacillus subtilis
201510-HDA (10-hydroxy-2-decenoic acid) is an unsaturated medium-chain fatty acid, which is the main active component of royal jelly. It has been shown to possess biological activity in antibacterial, immunoregulation, and antitumour. However, the underlying antibacterial mechanism of 10-HDA is unclear.

Absence of 10-Hydroxy-2-Decenoic Acid (10-HDA) in Bee-Collected Pollen
1986Much attention has been paid to the survival of bee-collected pollen in pellets as well as those sticking to body hairs. This interest stems from plant breeders concern to prevent contamination when using bees for pollination purposes in isolation cages on the one hand and, on the other hand, one would like to use bee-collected pollen to improve seed ...

Abstract The attenuated total reflectance-Fourier transform mid-infrared (ATR-FTMIR) and near-infrared (NIR) spectra of royal jelly samples were collected. Low- and mid-level data fusion strategies in combination with the partial least squares (PLS) regression algorithm were used for quantitative modeling analysis of 10-hydroxy-2-decenoic acid (10 ...

Antibacterial Activity and Mechanism of Action of 10-HDA Against Escherichia coli
201310-HDA (10-hydroxy-2-decenoic acid), an unsaturated fatty acid, is the main active component of royal jelly. It has been demonstrated that 10-HDA possesses remarkable antibacterial activities. However, it is unclear in terms of the underlying antibacterial mechanism of 10-HDA.

[Determination of 10-HDA in honeybee body by HPLC].
Se pu = Chinese journal of chromatography, 2010In the present work we found that in the honeybee body there exists an unsaturated fatty acid, trans-10-hydroxy-2-decenoic acid (10-HDA), which was known only to be present in royal jelly. We established the analytical method of 10-HDA in honeybee body by HPLC and simplified the extraction method of 10-HDA. In the optimum conditions the linear range of

Functional and health properties of 10-HDA acid – a unique component of the royal jelly
58 Croatian and 18 International Symposium of Agriculture : Proceedings, 2023Royal jelly is a special biologically active substance, with an extremely complex chemical composition, and is produced as a product of worker bees. The basic ingredient of royal jelly is 10-hydroxy-2-decenoic acid (10-HDA). It belongs to the group of unsaturated fatty acids and is not found anywhere in nature and cannot be synthesized.

SummaryWe report the analysis of Brazilian commercial bee products using high performance liquid chromatography, and a faster method, to detect trans-10-Hydroxy-2-Decenoic Acid or 10-Hydroxy-2-E-decenoic acid (10-HDA) in royal jelly. Determination was carried out using aqueous phosphoric acid 0.1% (pH 2.5)/methanol (50/50) as the mobile phase, and a ...

This paper reports the quantitative determination of 10-HDA in Chinese traditional medicine preparations by HPLC. Spherisorb C18 column was used. The mobile phase consisted of methanol-distilled water and phosphoric acid(45:55:0.5, V/V). The elute was monitored at 210 nm. The good linearity was shown between the concentration of 10-HDA and peak area in
