چکیده

Bee colonies were dosed with chloramphenicol (CAP) 1.0 g per hive (single dose in sucrose solution). Samples of honey were then collected at intervals over a 48-week period and samples of royal jelly, beeswax, honeybees and brood collected at intervals over a 12 week period. The mean concentration of CAP in the honey at 7 days after dosing was 26 μg/g, declining to 1.0 μg/g at 332 days. Application of the shook swarm procedure resulted in a mean concentration of CAP in honey of 26 μg/g at 7 days, declining to 0.1 μg/g at 332 days. The mean concentration of CAP in non-honey samples was in the range of 0.5 to 6.8 μg/g, and 0.2 to 3.3 μg/g at 7 days and 56 days, respectively. These results indicate that use of CAP can be detected up to 332 days after dosing even if the shook swarm procedure is used in an attempt to clean the hives. There was no evidence of any significant formation of bound CAP-glucose conjugates in honey.

چکیده

The present study determined the genetic variation at mrjps loci (mrjp3, mrjp5 and mrjp8) and evaluated the potential use of MRJPs as molecular markers for higher royal jelly production in Africanized honeybee colonies. The three analyzed loci produced a total of 17 alleles. This high allelic polymorphism indicated these loci could serve as genetic markers. The potential use of MRJPs as molecular markers for royal jelly production was evaluated by analyses of multiple linear regressions with EPD (expected progeny differences) values for royal jelly production. The variance analyses indicated that the mrjp3 repetitive region influenced the genetic value of queen’s offspring for royal jelly production. The determination coefficient (R2) for the significant alleles of the repetitive region of mrjp3 indicated that 36.85% of the EPD variation is explained by the variation of C, D and E alleles. Therefore, these three alleles present a considerable genetic effect on the variation of RJ production.

چکیده

Most of the studies on royal jelly (RJ) composition or properties as well as quality standards of commercially available royal jelly are based on RJ harvested three days (72 h) after grafting. In China, some beekeepers produce RJ harvested one (24 h) or two (48 h) days after grafting. There is a lack of knowledge about the quality of the royal jelly harvested earlier than 72 h. This study compared 32 colonies for their chemical compositions of RJ harvested at 24, 48 and 72 h after grafting, according to the proportion of moisture, protein, 10-HDA, total sugar and the value of acidity and superoxide dismutase activity. The analysis of RJ samples revealed that the composition varied significantly (for both fresh and dehydrated samples) and on some occasions above and below the range of present Chinese and Swiss standards. The results suggest that harvesting time should be considered when defining new quality standards of RJ. Keywordshoneybee–royal jelly–chemical composition–quality standard

چکیده

In this research, several royal jellies and commercial products containing royal jelly were analysed for their trans-10-hydroxy-2-decenoic acid (10-HDA) content by using a column liquid chromatography technique. Ten samples claimed to be pure royal jelly, containing 10-HDA between 0.75 and 2.54%. Seven samples claimed to contain royal jelly as an ingredient which ranged from non-detectable to 0.054%. The technique was found to be rapid with high recovery.

چکیده

Given the exceptional biological properties attributed to it, royal jelly (RJ) has considerable commercial appeal and is today utilised in many sectors, ranging from the pharmaceutical and food industries to the cosmetic and manufacturing sectors. This has resulted, among other things, in large-scale importation in countries where production is insufficient to meet domestic demand. Research capabilities thus need to be reinforced to permit both a reliable qualitative and quantitative evaluation of the different components and the implementation of analytical tests on commercially available products – RJ on its own or as an additive to new or traditional products – also for the purpose of identifying possible adulteration.

چکیده

Only one carboxylic acid, 10-hydroxy-2-decenoic acid, has previously been isolated from royal jelly. Small amounts of two additional acids, sebacic and 2-decendioic acid, have now been found in the ether-soluble portion of this special bee foodstuff. Evidence is presented in favor of the trans-configuration for naturally occurring 10-hydroxy-2-decenoic acid. Chromic acid oxidation of the hydroxy acid yields 2-decendioic acid.

چکیده

OBJECTIVES: To compare the effects of a single nocturnal dose of 3 honey products (eucalyptus honey, citrus honey, or labiatae honey) to placebo (silan date extract) on nocturnal cough and difficulty sleeping associated with childhood upper respiratory tract infections (URIs).

METHODS: A survey was administered to parents on 2 consecutive days, first on the day of presentation, when no medication had been given the previous evening, and the following day, when the study preparation was given before bedtime, based on a double-blind randomization plan. Participants included 300 children aged 1 to 5 years with URIs, nocturnal cough, and illness duration of ≤7 days from 6 general pediatric community clinics. Eligible children received a single dose of 10 g of eucalyptus honey, citrus honey, labiatae honey, or placebo administered 30 minutes before bedtime. Main outcome measures were cough frequency, cough severity, bothersome nature of cough, and child and parent sleep quality.

RESULTS: In all 3 honey products and the placebo group, there was a significant improvement from the night before treatment to the night of treatment. However, the improvement was greater in the honey groups for all the main outcome measures.

CONCLUSIONS: Parents rated the honey products higher than the silan date extract for symptomatic relief of their children’s nocturnal cough and sleep difficulty due to URI. Honey may be a preferable treatment for cough and sleep difficulty associated with childhood URI.
