I am looking for a purification protocol for a fatty acid found in royal jelly, namely 10-HDA (10-hydroxy-2-decenoic acid). Does anyone have experience with the separation and purification of this bioactive compound?
You can use a preparative LC equipped with a UV detector and any C18/C8 semi-prep or prep column (depending on your concentration target). Following an in-house developed Isocratic or gradient separation protocol using D.I water and methanol 10-HDA can easily be fractionated from royal jelly. Afterward, you can preserve your sample by applying lyophilization. The improved resolution is important not to include any impurity, therefore other than column chromatography, I would prefer to use an MPLC instrument and automated purification. I also suggest checking the final purified molecule at MS in non-targeted mode to see if non-UV absorbing impurity exists or not...
