“…In Tunisian propolis, dl-limonene was found in small amounts of 0.54%, 1.42% and 1.20%, respectively, in the samples of Zouarine, Zelligua and Beni Khalled. These results were different comparing to Croatian [13] and Brazilian propolis from Jaguari region [36], where high percentages of dl-limonene were detected, using hydrodistillation method. This compound is known with its anti-anxious and antidepressant benefits [35] [36] [37].…”

“…Only 6 volatile compounds present with low proportions (0.53% -0.082%) were not identified. Propolis sample collected from Zouarine was characterized by the highest number of compounds identified (47), followed by Zelligua (36) and Bizerte (30), while the lowest one was observed in the sample collected from Beni Khalled (24). The low quantity of volatile compounds identified in the Beni Khalled propolis could be due to the presence of waxes or may be related to flora.…”

In this study, four samples of Tunisian propolis were analyzed for their volatile compounds. Static Headspace technique coupled with gas chromatography-mass spectrometry (GC/MS) was used for the volatile profile characterization. Statistical investigation of the samples was made applying hierarchical clustering method, K-Means cluster and principal component analysis. Results showed that 47, 36, 30 and 24 different compounds were identified, respectively, in the samples from Zouarine, Zelligua, Bizerte and Beni Khalled. Propolis volatiles were dominated by monoterpene hydrocarbons. α-pinene was the major compound representing 81.14%, 82.67% and 90.74%, respectively, of the total propolis volatiles collected from Zelligua, Beni Khalled and Zouarine and only 45.22% of the sample from Bizerte which had a very different composition. The in vitro antifungal activity of the volatiles from all samples against Candida albicans was also assayed and reported.

“…Although the propolis envelope may not come into direct contact with larval food, volatile compounds present in propolis can diffuse through the hive, and possibly into the larval food, contributing to the complex way in which bees fight infections. Several studies have confirmed the activity of propolis volatiles against Gram-positive 15 , 34 – 36 , and Gram-negative bacteria 35 – 37 , as well as the inhibitory activity of non-volatile compounds against P . larvae 19 .…”

Honey bees have immune defenses both as individuals and as a colony (e.g., individual and social immunity). One form of honey bee social immunity is the collection of antimicrobial plant resins and the deposition of the resins as a propolis envelope within the nest. In this study, we tested the effects of the propolis envelope as a natural defense against Paenibacillus larvae, the causative agent of American foulbrood (AFB) disease. Using colonies with and without a propolis envelope, we quantified: 1) the antimicrobial activity of larval food fed to 1–2 day old larvae; and 2) clinical signs of AFB. Our results show that the antimicrobial activity of larval food was significantly higher when challenged colonies had a propolis envelope compared to colonies without the envelope. In addition, colonies with a propolis envelope had significantly reduced levels of AFB clinical signs two months following challenge. Our results indicate that the propolis envelope serves as an antimicrobial layer around the colony that helps protect the brood from bacterial pathogen infection, resulting in a lower colony-level infection load.

“…This compound has been reported to have a significant inhibitory effect on bacteria and contributes to the antimicrobial activity of propolis. [84]. Therefore, it can be said that M4 and M8 samples containing α-pinene probably have high antimicrobial activity.…”

Propolis is a resinous substance produced by honey bees from various plants they visit. Sixty-four propolis samples were collected from different localities of four districts (Merkez, Yüksekova, Şemdinli, and Çukurca) in Hakkari territory. Ethanol extracts of the propolis samples were prepared, and their chemical contents were determined by gas chromatography-mass spectroscopy (GC-MS). Flavonoids were generally found in a high concentration in Şemdinli samples of Turkey. Twenty-seven coumarins were identified in the 28 propolis samples among studied 64 ones. Except suberosin, the coumarins were never reported before in any propolis sample with Turkish origin. The propolis samples belonging to Yüksekova were found to be richer in coumarins than the others, and the most richest one among the Yüksekova apiaries, was found to be Akocak sample (Y2) with 41.99% total yield, followed by Akçalı sample (Y5) (30.86%). This is a first comprehensive and original report about the chemical profile of propolis samples from Hakkari. The propolis samples from Hakkari exhibited a chemical content rich in flavonoids including coumarins and furocoumarins.
