Studies on the lipids of royal jelly

Biochimica et Biophysica Acta (BBA) - Specialized Section on Lipids and Related Subjects, 1964
Abstract A chromatographic study has been conducted on the lipid components of the food of queen larvae (royal jelly) of the honeybee, Apis mellifera L. In addition to previously characterized decanoic acid derivatives, this material is shown to contain small amounts of a number of uncharacterized hydroxy acid components, two of which have been ...

Physicochemical characterisation of French royal jelly: Comparison with commercial royal jellies and royal jellies produced through artificial bee-feeding

Journal of Food Composition and Analysis, 2013
A reliable database is established from the analysis of 500 French royal jellies (RJ). Diversity of geographical origins, harvesting seasons, and forage sources were taken into account. Authenticity intervals for numerous physicochemical parameters have been established from French RJs, obtained without bee-feeding with artificial sugars or proteins ...

Royal jelly in focus

Insectes Sociaux, 2018
Honey bee (Apis spp.) royal jelly, a glandular secretion used to raise young larvae to future queens, has long been considered merely as food. Since queen larvae are raised upside down in their vertically oriented queen cells, royal jelly also needs to adhere the larvae to the cell ceiling to prevent the prospective queen from dropping out.

Neuroregulatory effect of royal jelly

The Journal of Nutritional Biochemistry
Royal jelly (RJ), a nutrient-rich secretion fed exclusively to queen honeybees, exhibits diverse biological activities. Due to limited insights into its effects on central nervous system (CNS)-related functions and pathologies, this review attempts to recapitalize the recent advances of neuroregulatory function of RJ in mammals and humans.

Some Phosphorus Compounds in Royal Jelly

Nature, 1964
SYSTEMATIC investigations, mainly during the past decade, have led to the discovery of a number of biologically highly valuable substances in the jelly of the honeybee. Comparatively little is known so far as its contents of phosphorus compounds are concerned.

Quantitative Analysis of Sugars in Royal Jelly

Nature, 1962
THE amount of carbohydrate in royal jelly, determined in terms of total reducing substances, has been investigated. The results are seen in tabular form in a review by Johansson1 and show concentrations of carbohydrate in fresh royal jelly ranging from 8.3 to 29.1 per cent by weight. During one of these investigations2 an additional test was conducted,
