Royal jelly fermented by honeybee queen (Apis mellifera)-derived Lactobacillus panisapium M1 enhances macrophage phagocytosis through the TLR2/MAPK/SR signaling pathway [PDF]
Background Royal jelly (RJ) has traditionally been used to maintain health, and its fatty acids (10-hydroxy decanoic acid and 10-hydroxy-2-decenoic acid) are reported to have immunomodulatory effects.

Oleic Acid Promotes the Biosynthesis of 10-Hydroxy-2-decenoic Acid via Species-Selective Remodeling of TAGs in Apis mellifera ligustica. [PDF]
This study aimed to assess the impact of oleic acid (OA) supplementation on the biosynthesis of 10-hydroxy-2-decenoic acid (10-HDA) in Apis mellifera ligustica. In experiment 1, varying concentrations of OA (2%, 4%, 6% and 8%) were added to an artificial diet for newly emerged bees reared in cages.

Effects of 10-Hydroxy-2-decenoic Acid and 10-Hydroxydecanoic Acid in Royal Jelly on Bone Metabolism in Ovariectomized Rats: A Pilot Study. [PDF]
Although previous studies have demonstrated that royal jelly (RJ) may have estrogenic properties and prevent postmenopausal bone loss, the underlying mechanisms are not fully understood. This animal study aimed to investigate the effects of specific fatty acids of RJ, 10-hydroxy-2-decenoic acid (10H2DA) and 10-hydroxydecanoic acid (10HDAA), in ...

10-Hydroxy-2-Decenoic Acid Prevents Ultraviolet A-Induced Expression of Lamin AÄ150 in Human Dermal Fibroblasts. [PDF]
10-Hydroxy-2-decenoic acid (10-HDA) as the main component of royal jelly has pharmacological characteristics. But the influence of 10-HDA on skin photoaging and photo damage is poorly understood. In the present study, we used 10-HAD immediately after UVA exposure and tested the effects on the attenuation of LMNAÄ150 expression in cultured human dermal ...

Down-regulation of aquaporin 9 gene transcription by 10-hydroxy-2-decenoic acid: A major fatty acid in royal jelly. [PDF]
Abstract10‐Hydroxy‐trans‐2‐decenoic acid (10H2DA) is a unique lipid component of royal jelly produced by worker honeybees that exerts insulin‐like effects. We herein investigated the effects of 10H2DA on the gene expression of aquaporin 9 (AQP9), which functions as a glycerol transporter in the liver, to clarify whether 10H2DA modulates energy ...

DETERMINATION OF 10 - HYDROXY - 2 - DECENOIC ACID IN ROYAL JELLY BY CAPILLARY ELECTROPHORESIS [PDF]
ABSTRACT Two commercial samples of Royal Jelly sold in Chile, consisting of two imported sample and another sample of known origin obtained freshly harvested from beekeepers were analyzed. The application of capillary electrophoresis (CE) for the separation and determination of the active compound, 10 hydroxy –2 – decenoic acid, in Royal Jelly (RJ) in ...

Synthesis of 10-Hydroxy-2-decenoic Acid (Royal Jelly Acid) from the Butadiene Telomer [PDF]
Abstract Ethyl 2-acetyl-4,9-decadienoate obtained by palladium catalyzed reaction of butadiene and ethyl acetoacetate was converted to 4,9-decadienoate. Hydroboration of the terminal olefin gave 10-hydroxy-4-decenoate. After hydrogenation and protection of the hydroxyl group, the double bond was created at the conjugated position by ...
