 Title    Propolis from the Mediterranean Region: Chemical Composition and Antimicrobial Activity  
 Abstract    The chemical composition of propolis from Bulgaria, Turkey, Greece and Algeria was investigated by GC-MS. All of them contained mainly flavonoids and esters of caffeic and ferulic acids, which indicated that their main source are buds of poplars of the taxonomic section Aegieros. Some Turkish samples contained a low percent of diterpenic acids, while in Algerian samples significant amounts of a hydroxyditerpenic acid (M=322, its structure not determined by its MS) were found. All samples showed significant antibacterial and weak to moderate antifungal activity.

 Title    Egyptian Propolis: 1-Antimicrobial Activity and Chemical Composition of Upper Egypt Propolis  
 Abstract    The antimicrobial activity of four propolis samples collected from Upper Egypt against Staphylococcus aureus; Escherichia coli and Candida albicans was evaluated. There was a variation in the antimicrobial activity according to the propolis origin. Banisweif propolis showed the highest antimicrobial activity against Staphylococcus aureus, Escherichia coli and Candida albicans, but Fayoum propolis had moderate activity against all tested pathogens. Propolis collected from Assiut and Souhag gave lower antimicrobial activity. Propolis samples were investigated by GC/MS, 71 compounds were identified, 14 being new for propolis. Banisweif propolis is characterized by the presence of 7 caffeate esters and 4 triterpenoids. Fayoum propolis showed the highest amount of lactic acid and the presence of 3 chalcones. But Assiut propolis is characterized by the presence of 4 prenylated coumar-ates. Souhag propolis is characterized by the presence of 5 aliphatic dicarboxylic acids and some other new compounds to propolis.

 Title    Antibacterial Activity and Chemical Composition of Turkish Propolis  
 Abstract    The antibacterial activities of propolis samples have been examined in vitro, according to the principles accepted for the determination of a similar activity of antibiotics with the use of solid and liquid media. It has been found that propolis extracts showed antibacterial activ­ ity through a range of commonly encountered gram positive cocci (5. aureus, beta hem. Streptococus), but had weak activity against gram negative bacteria (E . coli, P. aeruginosa). GC/MS analysis showed that propolis samples contain a variety of chemical compounds in­ cluding aromatic compounds, fatty acid esters and sesquiterpenes.

 Title    A Novel Caffeic Acid Derivative and Other Constituents of Populus Bud Excretion and Propolis (Bee-Glue)  
 Abstract    E ck h a rd W ollenw eber, Y oshinori A sakaw a*, D etlef Schillo, U lrich L eh m an n , and H eid ru n W eigel The bud exudates of Populus nigra, P. trichocarpa, and P. grandidentata x tremuloides were analyzed for the presence of phenolics and flavonoids. A novel natural product, caffeic acid y.y-dimethylallyl ester, was identified from P. nigra, along with further phenolics such as /?-hydroxy-acetophenone, dimethyl caffeic acid, cinnamoyl cinnamata and vanillin. The flavonoid aglycones correspond to those reported earlier. Propolis samples from the Sonoran Desert were shown to exhibit the flavonoid pattern that is typical for poplar bud exudates, thus confirming this material as the major source for bee-glue. Only a single flavonoid might originate from the leaf exudate of a desert shrub.

 Title    Synthesis of Two Allergenic Constituents of Propolis and Poplar Bud Excretion  
 Abstract    The prenyl ester and the phenylethyl ester of caffeic acid, formed in the bud excretion of poplar species, were shown recently to be the major contact allergens in bee-glue. An unambiguous synthesis of these compounds, based on the reaction of caffeic acid with l-bromo-3-methyl-2-butene and with ß-bromoethylbenzene, respectively, is reported. The synthetic products confirm the previously described structures of the natural products and allow further testing of their allergenic properties.

 Title    Trace Elements in Propolis and in its Ethanolic Extract (E E P ) as Determined by Neutron Activation Analysis  
 Abstract    Propolis is a natural composite balsam, manufactured by honey bees, and active biochemically. Some of its biologi­ cal effects are attributed to its ability to stimulate enzymatic systems, which in many instances involve trace elements. In the present study we assayed propolis and its ethanolic ex­ tract (EEP) for trace elements, and quantified them with the aid of neutron activation analysis. Four elements that have been detected in propolis and EEP for the first time are Na. Cr, Co (ppm) and Ag (ppb). The wide concentra­ tion range of the inorganic components in various batches of propolis and EEP is due to the difference in their extrac­ tion capacities, and to the variability in the environmental pollutants and the flora at the beehive sites.

 Title    Biochemical Activities of Propolis Extracts I. Standardization and Antioxidative Properties of Ethanolic and Aqueous Derivatives  
 Abstract    Ethanolic extracts of Propolis are used as antiinflammatory and wound healing drugs since ancient times. In order to facilitate a comparison of different extracts, the standardization on the basis of quantitative determination of prominent components of these extracts has been substituted for simple biochemical "activity" tests. One of these activity tests bases on the in­ hibition of peroxidase-catalyzed oxidation of indole acetic acid indicating the presence of a defined mixture of monophenolic and diphenolic compounds. Other tests (diaphorase-cata-lyzed reductions and xanthine oxidase-catalyzed oxidations) demonstrate significant radical scavenging properties. Water-soluble extracts of propolis exhibit higher antioxidative and inhibitory activities as compared to the ethanolic extract.

 Title    Phenolic Composition of Propolis from China and from South America  
 Abstract    Flavonoids and other phenolic compounds were determined in 15 samples of propolis originating from China, from Brazil, and from Uruguay. A total of 24 compounds were identified using mainly HPLC and a few other analytical methods. The most abundant com­ pounds found were benzoic acid and benzaldehyde derivatives, flavones, flavonols. and flava-nones. 80% of the samples contained at least 22 g/100 g of flavonoids, primarily acacetin, isorhamnetin, apigenin, and pinocembrin. The flavonoid patterns were sufficiently distinctive to permit discrimination between propolis from China, from Uruguay, and from Brazil.

 Title    Potent Free Radical Scavenging Activity of Propol Isolated from Brazilian Propolis  
 Abstract    We evaluated free radical scavenging activity of the water, methanol and chloroform ex­ tracts of propolis in l,l-diphenyl-2-picrylhydrazyl (DPPH) free radical and xanthine-xanthine oxidase (XO D) generated superoxide anion assay systems. The free radical scavenging activ­ ity guided fractionation and chemical analysis led to the isolation of a new compound, propol {3-[4-hydroxy-3-(3-oxo-but-l-enyl)-phenyl]-acrylic acid) from the water extract, which was more potent than most common antioxidants such as vitamin C and vitamin E (a-tocopherol) in these assay systems.

 Title    A New Benzo-y-pyran Derivative Isolated from Propolis  
 Abstract    The methanol extract of Brazilian propolis was fractionated by HPLC, based on human hepatocellular carcinoma (HuH 13) cell cytotoxicity assay. A new benzo-y-pyran derivative (PM-3) with a molecular formula of Q 9 H 2 2 O3 (MW: 298.38) was isolated. The structure of this colorless compound was determined as 3-[2-dimethyl-8-(3-methyl-2-butenyl) benzopy-ran]-6 -propenoic acid. This compound was chemically synthesized by cyclisation of artepillin C (3-[4-hydroxy-3,5-bis (3-methyl-2-butenyl) phenyl]-2-propenoic acid).

 Title    Preliminary Report on the Effects of Propolis on Wound Healing in the Dental Pulp  
 Abstract    The purpose of this investigation was to determ ine the antimicrobial and healing potential of propolis on direct dental pulp exposures. This study used 25 adult male rats. Pulp expo­ sures were perform ed and animals were allocated to propolis and calcium hydroxide (C a(O H) 2 groups. Animals were killed on days 5, 7, 10, and 14. The teeth were routinely processed for histological evaluation. N on-param etric tests were employed to analyze the data. No significant differences were found between study groups on the wound healing of the dental pulp. Both substances were com parable in exhibiting normal reorganization of the pulp and no increased vascularity, and were equally efficacious in maintaining a low inflam­ matory and microbial cell population as well as in stimulating the formation of reparative dentin.
