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.

Antioxidant capacity of major royal jelly proteins of honeybee (Apis mellifera) royal jelly
Journal of Asia-Pacific Entomology, 2020Abstract Major royal jelly proteins (MRJPs) of honeybee royal jelly (RJ) exhibit antimicrobial and antioxidant activities. Although MRJPs of Apis mellifera RJ (AmMRJPs) responsible for antibacterial activity have been identified, AmMRJPs with antioxidant effects remain to be elucidated.

Experientia, 1984
A compound with immunoreactivity, and TLC and GLC mobility of testosterone was isolated from royal jelly of honeybee (Apis mellifera). This is the first demonstration of vertebrate steroid hormone in this species.

Some Phosphorus Compounds in Royal Jelly
Nature, 1964SYSTEMATIC 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.

Year Round Royal Jelly Production Determining the Best Season of Producing Royal Jelly
DMMMSU Research and Extension Journal, 2020This research was conceptualized to determine the preeminent season for the production of royal jelly from the honeybee Apis mellifera. Three strong double-chambered colonies of equal strength were utilized throughout the duration of the study and the grafting method was applied to facilitate the production of the jelly by the bees.

Today, interest in functional foods is increasing. Royal jelly, one of the bee products, is among the functional foods. Royal jelly (RJ) is secreted by worker bees at a young age (5-15 days) and enables worker bee larvae to turn into queen bee larvae in the colony, it is also known as caste determinant food . The content of RJ mainly includes water (60

New synthesis of royal jelly acid
Journal of Chemical Ecology, 1982A new synthesis of (E)-10-hydroxy-2-decenoic acid (royal jelly acid) is described, starting from 8-bromo-1-octanol via condensation of malonic acid with 8-hydroxyoctanal or 8-acetoxyoctanal.

Biologically Active Substances in Royal Jelly
1966Publisher Summary This chapter discusses biologically active substances in royal jelly. The composition of royal jelly must be compared with that of worker jelly to determine whether there are qualitative and quantitative differences in these foods. Such analyses would serve as a basis for the development of partial or complete synthetic larval foods.

Royal jelly counteracts bucks’ “summer infertility”
Animal Reproduction Science, 2010Exposure of male rabbits to heat stress during summer adversely affects their fertility leading to major production losses. A total number of 24 male rabbits were randomly divided into four experimental groups exposed to temperatures ranging from a high of 32 degrees C to a low of 23 degrees C.
