“…Propolis is a resinous mixture used to protect hives from many diseases and threats. The composition of propolis depends mainly on the floral source; it contains nearly 40-50% resins, 30% wax, 5-10% essential oils and 3-10% phenolic substances, such as phenolic acids, flavonoids, tannins and so on 14,15 . Propolis contains a number of bioactive substances such as phenolic compounds and essential oils.…”

“…For these reasons, propolis is a good pharmaceutical agent and propolis extracts have been used for different purposes such as throat sprays, cosmetics and toothpaste to boost the immune system 19,20 . The antioxidant and anticancer activities of propolis samples cited in the literature make propolis attractive for scientific enquiry and screening as a novel therapeutic natural agent 14,15,19,20 . Taking into account the circumstantial literature, we endeavored to undertake an in vitro assessment of ethanolic propolis extracts (EPEs) to determine their effect on H. pylori growth inhibition and urease inhibition.…”

There is considerable interest in alternative approaches to inhibit Helicobacter pylori (H. pylori) and thus treat many stomach diseases. Propolis is a pharmaceutical mixture containing many natural bioactive substances. The aim of this study was to use propolis samples to treat H. pylori. The anti-H. pylori and anti-urease activities of 15 different ethanolic propolis extracts (EPEs) were tested. The total phenolic contents and total flavonoid contents of the EPE were also measured. The agar-well diffusion assay was carried out on H. pylori strain J99 and the inhibition zones were measured and compared with standards. All propolis extracts showed high inhibition of H. pylori J99, with inhibition diameters ranging from 31.0 to 47.0 mm. Helicobacter pylori urease inhibitory activity was measured using the phenol-hypochlorite assay; all EPEs showed significant inhibition against the enzyme, with inhibition concentrations (IC 50 ; mg/mL) ranging from 0.260 to 1.525 mg/mL. The degree of inhibition was related to the phenolic content of the EPE. In conclusion, propolis extract was found to be a good inhibitor that can be used in H. pylori treatment to improve human health.

“…Despite the great diversity of honeys produced in Anatolia, there have been limited studies for the characterization and classification by botanical or geographical origin. In addition, most of the studies are limited for the compositional analysis (29)(30)(31)(32)(33)(34)(35)(36)(37)(38).…”

Chaste tree and pine honeys were bought from three different producers (natural) and three local markets (commercial). The honey samples were stored for 30 months at room temperature. The shelf life of the samples was estimated for indices of HMF and diastase activity. The values for HMF formation and diastase deactivation fitted to a zero-order reaction. The highest rate of HMF formation was observed in the chaste tree honey as 2.674±0.013 mg/kg/month while the least value was observed in the pine honey as 0.435±0.037 mg/kg/month. The maximum diastase deactivation was determined in the natural chaste tree honey as 0.613±0.000 DU/kg/months and the minimum was 0.318±0.002 DU/kg/month for the commercial chaste tree sample. In terms of HMF, all honeys except commercial chaste tree honey, have exhibited longer shelf life than 30 months of storage. The results showed that the shelf life of the commercial honeys depend on the botanical origin, pH, electrical conductivity, temperature and storage.Keywords: Chaste tree, pine honey, shelf life, HMF, diastase. HAYIT (Vitex agnus castus) VE ÇAM BALININ RAF ÖMRÜNÜN BELİRLENMESİ ÖzHay›t ve çam ballar› üç farkl› üretici (do¤al) ve üç farkl› yerel marketten (ticari) sat›n al›nm›fl ve bal örnekleri 30 ay oda s›cakl›¤›nda depolanm›flt›r. Bal örneklerinin raf ömrü HMF miktar› ve diastaz aktivite indeksleri üzerinden tahmin edilmifltir. HMF oluflumu ve diastaz deaktivasyonu s›f›r›nc› dereceden kinetik modele uyumlu bulunmufltur. En yüksek HMF oluflum h›z› hay›t ballar›nda 2.674±0.013 mg/kg/ay olarak hesaplan›rken en düflük h›z çam bal›nda 0.435±0.037 mg/kg/ay olarak belirlenmifltir. Diastaz say›s› bak›m›ndan ise, en yüksek (0.613±0.000 DU/kg/ay) ve en düflük (0.318±0.002 DU/kg/ay) deaktivasyon h›z› do¤al ve ticari hay›t ballar›nda belirlenmifltir. Ballar›n 30 ay depolanmas› sonunda HMF bak›m›ndan ticari hay›t bal› hariç di¤er tüm ballar daha uzun raf ömrüne sahip olmufltur. Bu sonuçlar ticari ballar›n raf ömrünün botanik orjin, pH, elektriksel iletkenlik, s›cakl›k ve depolamaya ba¤l› oldu¤unu göstermektedir.Anahtar kelimeler: Hay›t bal›, çam bal›, raf ömrü, HMF, diastaz.
