GC-MS analysis of honeybee products derived from medicinal plants

Abstract

Background Honeybees provide a wealth of valuable natural products containing health-promoting bioactive compounds, including honey, bee bread, bee venom, bee pollen, propolis, and royal jelly. In the present study, we investigated the chemical composition of four honeybee products (bees, honey, royal jelly, and bee bread) derived from three medicinal plants (marjoram, trifolium, and citrus) using headspace GC-MS. Results GC-MS analysis coupled with the headspace method resulted in identification of 24 volatile compounds in marjoram honey, 14 volatile compounds in trifolium honey, and 25 volatile compounds in citrus honey, e.g., some of these compounds appeared in all three types of honey aroma, which are 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one, 2-furancarboxaldehyde, 5-(hydroxymethyl) and other unique compounds specific for each type where 23 compounds were from marjoram bees, 38 compounds from trifolium bees, and about 37 compounds were identified in citrus bees where 2,4-decadienal, (E, E) and methyl N-methyl anthranilate were common in all. Furthermore, the volatile compounds of all three types of royal jelly aroma were acetic acid, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one, 8-nonen-2-one and furfural where one compound appeared in both marjoram and trifolium royal jelly that is 2-furancarboxaldehyde,5-(Hydroxymethyl) and the volatile compounds in marjoram and citrus are 2,3-butanediol and 5-methylfurfural also only one volatile compound appear in both trifolium and citrus royal jelly that is furfur alcohol, Finally, 3 compounds from marjoram bee bread, 30 volatile compounds from trifolium bee bread, and 3 volatile compounds in citrus bee bread were identified. Conclusions A detailed metabolomic analysis of the four honey product groups revealed an intriguing chemical diversity, with each sample exhibiting its own chemical fingerprint.

“…On the other hand, the compound 5-(hydroxymethyl)-2-furancarbaldehyde, identified by GC/MS in this work, has been reported in several sources, including the fruit of Gardenia gummifera (Vinaykumar et al, 2020), extracts of Callistemon lanceolatus with anticancer properties (Ahmad et al, 2018) and in honey (Montaser et al, 2023). It has also been found to exhibit potent antioxidant effects in aged garlic (Wang et al, 2016).…”
