Separation and determination of 10-hydroxy-2-decenoic acid in royal jelly by capillary electrophoresis

Chromatographia, 1995
The application of capillary electrophoresis (CE) to the separation and determination of the active ingredient, 10-hydroxy-2-decenoic acid, in royal jelly with direct on-column UV detection at 214 nm is described. Using a cathodic injection and anodic detection scheme, 10-hydroxy-2-decenoic acid (10-HDA) was separated and detected in less than 10 min ...

Absence of 10-Hydroxy-2-Decenoic Acid (10-HDA) in Bee-Collected Pollen

1986
Much 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 ...

10-Hydroxy-2-decenoic acid inhibiting the proliferation of fibroblast-like synoviocytes by PI3K–AKT pathway

International Immunopharmacology, 2015
To reveal the mechanism of 10H2DA inhibiting the proliferation of fibroblast-like synoviocytes (FLSs) of RA patients. Cell proliferation, HDAC activity and histone acetylation level of FLS cells treated with 10H2DA were detected by MTT assay, Colorimetric HDAC Activity Assay and Western-blot.

Production of 10‐Hydroxy‐2‐decenoic Acid from Decanoic Acid via Whole‐Cell Catalysis in Engineered Escherichia coli

ChemSusChem, 2021
Abstract10‐Hydroxy‐2‐decenoic acid (10‐HDA) is a terminal hydroxylated medium‐chain α,β‐unsaturated carboxylic acid that performs various unique physiological activities and has a wide market value. Therefore, development of an environmentally friendly, safe, and high‐efficiency route to synthesize 10‐HDA is required.

Comparative proteomic analysis provides insight into 10-hydroxy-2-decenoic acid biosynthesis in honey bee workers

Amino Acids, 2017
10-Hydroxy-2-decenoic acid (10-HDA) is the major compound produced from the mandibular glands (MGs) of honey bee workers. However, little information is available on the molecular mechanisms of 10-HDA biosynthesis. In our study, based on investigating the 10-HDA secretion pattern and the morphological characteristics of MGs from honey bee workers of ...

Determination of 10‐Hydroxy‐2‐Decenoic Acid of Royal Jelly Using Near‐Infrared Spectroscopy Combined with Chemometrics

Journal of Food Science, 2019
Abstract A rapid quantitative analysis model for determining the hydroxy‐2‐decenoic acid (10‐HDA) content of royal jelly based on near‐infrared spectroscopy combining with PLS has been developed. Firstly, near‐infrared spectra of 232 royal jelly samples with different 10‐HDA concentrations (0.35% to 2.44%) were be

[The research of 10-hydroxy-2-decenoic acid on experiment hyperlipoidemic rat].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2004
To study the pharmacological effect of 10-hydroxy-2-decenoic acid(10-HDA) in experiment hyperlipoidemic rat.Preventive and therapeutic effects of 10-HDA were tested on hyperlioidemic rat model induced by high fat food.10-HDA could reduce the content of TC, TG and beta-lioprotein, raise the content of HDL, which showed 10-HDA had preventive and ...
