Avarol effectively inhibits bacillus cereus growth

This work extends in vitro screening of antibacterial activity of avarol on four selected pathogenic bacteria associated with psoriasis (Bacillus cereus, Clostridium sporogenes, Enterococcus faecalis and Staphylococcus aureus). Avarol exhibited a moderate activity with minimum inhibitory and minimum bactericidal concentrations ranged from 0.78-1.56 and 3.12-18.75 μg/mL, respectively. It proved to be more effective against B. cereus in comparison to the both positive controls applied, gentamycin and ampicillin. According to the experimental data, this marine natural product may inspire development of new antibiotics with an enhanced therapeutic index, at first place those targeting B. cereus

An Insight Into Selected Properties of Merlot Wines Obtained from Three New Clone Candidates

Covering the period 2009-2012, the quality of Merlot wines obtained from three new clone candidates (namely Nos. 022, 025 and 029, respectively; fourth phase of clonal selection) developed in the Republic of Serbia was examined. The following parameters were determined: Folin-Ciocalteu (FC) index, pH value, total acidity, volatile acids, aldehydes, esters, relative density and ash. In comparison with the standard Merlot wine (originating from mother vine), FC index (from 35.73 to 37.15) and tasting score (from 17.89 to 17.95) were higher for the wines of all three clone candidates tested. These findings are in good agreement with the observed trend for the viticultural parameters indicating better properties of the new Merlot clone candidates versus mother

Flavonoidi iz nadzemnih delova Onobrychis montana subsp. scardica

Rutin (1, main constituent) and two flavone C-glycosides, vitexin (2) and vitexin 2 ''-O-alpha-rhamnopyranoside (3) were isolated from the aerial parts of Onobrychis montana subsp. scardica. They were identified by (1)H-NMR, (13)C-NMR and UV-Vis spectroscopy (procedure with shift reagents), and high resolution ESI-MS. A relatively high content of 1 (5.27 mg/g of dry plant material), measured by HPLC, indicated O. montana subsp. scardica as a new natural source of this biologically active compound. The isolated flavonoid compounds might be of value as chemotaxonomic markers.Iz nadzemnih delova Onobrychis montana subsp. scardica izolovani su rutin (1, glavni sastojak) i dva flavonoidna S-glikozida, viteksin (2) i njegov 2''-O-α-ramnopiranozid (3). Njihova struktura je određena primenom 1H-NMR, 13C-NMR i UV spektroskopije (procedura sa reagensima UV-pomeranja) i masene spektrometrije visokog razlaganja (HR-ESI-MS). Relativno visok sadržaj rutina (5.27 mg/g suvog materijala) određen pomoću tečne hromatografije (HPLC), ukazuje na O. montana subsp. scardica kao nov prirodni izvor ovog biološki aktivnog jedinjenja. Izolovana jedinjenja mogu biti i od vrednosti kao hemotaksonomski markeri

In vitro Radioprotective Activity of the Bryozoan Hyalinella punctata

The objective of the present study was in vitro evaluation of radioprotective activity of the freshwater bryozoan Hyalinella punctata on cultured human peripheral blood lymphocytes after irradiation with 2 gy of Co-60 gamma-rays. Since its water extract at concentration 0.001 mg/mL reduced the incidence of radiation-induced micronuclei for almost 30 %, it could be considered as a promising source of new natural products with the aforementined activity. Both the content of sulphur (1.17%) determined by gravimetric method and infrared absorption frequences (76 % similarity with those of bacitracin) of the investigated extract indicate the presence of organic sulphur compound(s) such as cyclic peptides and polypeptides which might be responsible for the observed radioprotectio
