The objective of this work is to analyze and identify the components in propolis samples collected from the South-Eastern Mediterranean region of Anatolia (Hatay province) and South Marmara region (Bursa province) during 2007. The components of both propolis samples were identified by GS-MS analysis. The results of chemical composition show that aromatic acids, aromatic acid esters, flavanols, cinnamic acid esters have been found in two different propolis samples. Biologically active chemical constituents of propolis are highly variable, depending on the plant species, geographic area, and on the season of collection. The antifungal, antibacterial and antiviral properties of the studied samples were microbiologically analyzed for candida strains and the results are presented in the second part of this paper. Keywords: Bursa propolis, Hatay propolis, components identification. INTRODUCTION Recently, new drug researches are focused on natural products. Among these kinds of natural products, one of the most interesting natural product is propolis. Propolis is a bee product which has many pharmacological properties and also used in traditional medicine. Various pharmacological properties of propolis have been reported such as antifungal, antibacterial and antiviral properties. Some natural products like propolis are especially candidates to be new antimicrobial substances in these works. In previous studies, propolis has been reported to be effective against yeast-like fungi (Aksoy et al., 2007; Duran et al., 2008; Onlen et al., 2007a; Duran et al., 2006; Oksuz et al., 2005; Allahverdiyev, 2004; Onlen et al., 2007b). The pharmacological properties of propolis are main attributed to the presence of various components (Banskota, Tezuka and Kadota, 1978). Biologically active chemical constituents of propolis are highly variable, depending on the plant species, geographic area, and on the season of collection (Ghisalberti, 1978). The fungi, especially yeasts belonging to the genus Candida are potentially pathogenic agents for human. Candida species especially C.albicans is found in the normal flora of mouth and gastrointestinal tract of human. Candida strains are opportunistic pathogenic fungi in humans which can cause either septicaemic or mucosal infections (Odds, 1994). These kinds of fungal infections are an important cause of morbidity and mortality hospitalized patients (Beck-Sague and Jarvis, 1993; Edmond et al., 1999; Pittet et al., 1997; Safdar and Armstrong, 2001). 211
In this study, we aimed to investigate the existance of synergistic activities of Hatay and Bursa propolis with Amphotericin B against some azole-resistant Candida strains. MATERIALS AND METHODS Sample Collection Propolis samples were collected from the South-Eastern Mediterranean region of Anatolia (Hatay province) and South Marmara region (Bursa province) during 2007. Hand-collected propolis samples were kept in a dry and dark place and stored at 4 C until their processing. Each of the propolis samples were sliced into small pieces after cooling at -40 C and then grated. The samples were dissolved in 96% ethanol (1:10, w/v) at 25 C for 14 days in clean dark-brown glass bottles. Airtight bottles shaked up for 3 minutes in every 6 hours for a period of 15 days. After extraction period, the supernatant was filtered twice with Whatman No.4 and No.1 filter papers. The ethyl alcohol extract was then evaporated to dryness under vacuum. Five micrograms of residue were mixed with 75 µl of dry pyridine and 50 µl bis (trimethylsilyl) trifluoroacetamide, heated and supernatant was analyzed by GC-MS (Sorkun, Suer, and Salih, 2001).

Substances Bursa Propolis Hatay Propolis Hinokione 0.96-2-Heptadecanoate - 0.33 The variability of constituents of propolis in two samples showed that they were collected from different plants depending on the geographic location. The pharmacological properties of propolis are principally attributed to the presence of various components (Banskota, A.H., Tezuka, Y. and Kadota, 1978). Biologically active chemical constituents of propolis are highly variable, depending on the plant species, geographic area, and on the season of collection (Ghisalberti, 1978). In the literature, the antimicrobial activity of propolis was reported to associate with the presence of flavonoids and derivatives of caffeic acid (Salomao et al., 2004; Prytzyk et al., 2003). It was reported that aromatic acids, aromatic acid esters, flavanols, cinnamic acid esters have been found in two different propolis samples. CONCLUSIONS Propolis may be an important prospect in the treatment of azole-resistant yeast. Although the effects of these two kinds of propolis against the Candida spp. in vitro are promising, further investigation such as microbiological, pharmacological and clinical trials are required.
