Abstract:
SummaryEmodin and its glycoside frangulin B were isolated from the plant Rhamnus formosana. Emodin inhibited the aggregation of rabbit platelets induced by arachidonic acid and collagen, without affecting that by ADP or PAF, while emodin acetate had no any antiplatelet effect. Frangulin B inhibited selectively and concentration-dependently collagen-induced aggregation and ATP release in rabbit platelets, without affecting those induced by arachidonic acid, ADP, PAF and thrombin. Frangulin B also inhibited the platelet aggregation induced by trimucytin which was reported to be a collagen receptor agonist isolated from Trimeresurus muscrosquamatus snake venom. The aggregability of platelets inhibited by frangulin B could be recovered after washing the platelets. Frangulin B also selectively suppressed the thromboxane B2 formation caused by collagen, but not those by arachidonic acid and thrombin. Similarly, the formation of inositol phosphate caused by collagen was also suppressed by frangulin B, while that of PAF or thrombin was not affected. In the presence of PGE1, frangulin B also decreased Mg2+-dependent platelet adhesion to collagen. It is concluded that frangulin B may be an antagonist of collagen receptor in platelet membrane.

Abstract:
The use of medicinal plants is becoming increasingly appreciated in suppressing cancer growth and cancer prevention. In this study the antiproliferative effects of the water extracts of previously obtained ethanolic dry extracts of three different medicinal plants (Camellia sinensis, Frangula alnus from two different places and Rosmarinus officinalis) using cell lines derived from human cervix adenocarcinoma (Hela cells) were investigated. The extract of Camellia sinensis exhibited significant cytotoxic effect against Hela cells (IC50 40.88 ?g/ml). Screening in Hela cells revealed a moderate cytotoxic effect (IC50 80.26?g/ml) of the extract of Rosmarinus officinalis, a mild cytotoxic effect (IC50 148.05 ?g/ml) of the extract of Frangula alnus (originating in Bosnia), and the extract of Frangula alnus (originating in Serbia) did not show active cytotoxicity (IC50 > 200 ?g/ml). The best antiproliferative properties are those of Camellia sinensis, followed by Rosmarinus officinalis, and the least effective was Frangula alnus. As regards geographic origin, the Frangula alnus from Bosnia possessed better antiproliferative effects than Frangula alnus from Serbia.

U poslednjoj fazi rada, izvršeno je određivanje sposobnosti pulvisa i etanolnog ekstrakta komercijalnog  preparata Vitalplant® da inhibiraju oksidaciju lipida u keksu, primenom spektrofotometrijskih testova “skevindžer“ aktivnosti  na DPPH˙ radikale i MDA testa. Ispitane biljne sirovine, kao i komercijalni preparat Vitalplant® su bogat izvor jedinjenja iz klase biljnih fenola. Sve ispitane biljne droge poseduju antioksidantnu aktivnost, koja se značajno ne menja usled termičkog tretmana. Dodatak biljne mešavine Vitalplant® , upravo proporcionalno njenom sadržaju,  dovodi do povećanja antioksidantne aktivnosti keksa i smanjenja stepena lipidne peroksidacije. 
In this paper, quantitative determination and identification of plant phenolics and flavonoids of ethanolic extracts obtained from parsley fruit (Petroselini fructus), buckthorn bark (Frangulae cortex), mint leaves (Mentha piperitae folium), caraway fruit  (Carvi fructus), birch leaves (Betulae folium), as well as from commercial preparation Vitalplant® ((Frangulae cortex(35 %), Mentha piperitae folium (20%), Carvi fructus(20 %), Petroselini fructus (25 %)) was performed. In addition, antioxidant  activity of ethanolic extracts was tested, by applying direct, ESR “spin trap“  spectroscopic methods for the determination of scavenging activity on superoxide anion and hydroxyl radicals, and indirect, spectrophotometric methods for the determination of DPPH˙ radical scavenging activity, reducing power, chelating activity and antioxidant activity in  β-carotene-linoleic acid model system. Moreover, thermal stability of the ethanolic extracts was tested in order to get insight into possible application of the extracts in bakery products. Finally, the ability of the commercial preparation Vitalplant®, in the form of powder and extract, to inhibit oxidative changes of cookies was tested by applying spectrophotometric DPPH radical scavenging and MDA tests.According to obtained results, investigated plant samples, including commercial preparation Vitalplant®, are rich source of plant phenolics. Investigated plant drugs possess antioxidant activity, which is not significantly changed after the thermal treatment. Cookie supplementation with commercial preparation Vitalplant® results in  better oxidative stability of lipids and enhanced antioxidant activity of the cookies.

In this project, we undertook to explore the action mechanism of Frangulin B, a main extract of Rhamnus formosana Matsumb, suppresses thrombin, endothelin-1 (ET-1) or bradykinin (BK)-induced connective tissue growth factor (CTGF) expression in human lung fibroblasts (WI-38). Pretreatment of cells with Frangulin B (1-10 ?嵱) attenuated thrombin, ET-1 and BK-induced CTGF expression in a concentration dependent manner. Cell were treated various concentrations of Frangulin B (1-100?嵱) , Frangulin B has no effect on WI-38 cell viability. Moreover, Frangulin B (1-10 ?嵱) inhibited signal transducer and activator of transcription 3 (STAT-3) and janus kinase 2 (JAK-2) phosphorylation in a concentration-dependent manner. However, Frangulin B (1-10 ?嵱) could not inhibit mitogen-activated protein kinases (MAPKs) including extracellular regulated protein kinase (ERK) and c-Jun-N-terminal kinase (JNK) phosphorylation. Using in vitro JAK-2 kinase assay, we found that Frangulin B directly inhibitied the JAK-2 kinase activity. In addition, Frangulin B inhibited thrombin-induced collagen I and ??-SMA expression. Taken together, we demonstrate Frangulin B inhibited thrombin-induced profibrosis protein in WI-38 cells; this inhibition is mediated by suppressing JAK-2 enzyme activity. Our results suggest that Frangulin B is a novel JAK-2 inhibitor and may be an effective anti-fibrosis drug.

Abstract:
Le nerprun bourdaine (Rhamnus frangula L.) est une espèce exotique qui envahit plusieurs régions du sud du Québec, et plus particulièrement la région administrative de l'Estrie. Actuellement, on connaît encore peu l'écologie de l'espèce dans le contexte québécois et il n’existe pas de portrait d’ensemble de sa distribution dans les forêts tempérées de cette région. Dans ce contexte, le premier objectif du projet était de cartographier par télédétection la distribution du nerprun bourdaine dans deux secteurs de l'Estrie. Un second objectif était d'évaluer les variables environnementales déterminantes pour expliquer le recouvrement de nerprun bourdaine. La phénologie du nerprun bourdaine diffère de celle de la plupart des espèces indigènes arborescentes puisque ses feuilles tombent plus tard en automne. Cette caractéristique a permis de cartographier, par démixage spectral, la probabilité d'occurrence du nerprun bourdaine grâce à une série temporelle d'images du capteur OLI de Landsat 8. Le recouvrement du nerprun bourdaine a été calculé dans 119 placettes sur le terrain. La cartographie résultante a montré un accord de 69% avec les données terrain. Une image SPOT-7, dont la résolution spatiale est plus fine, a ensuite été utilisée, mais n’a pas permis d'améliorer la cartographie, puisque la date d’acquisition de l’image n’était pas optimale dû à un manque de disponibilité. Concernant le second objectif de la recherche, la variable la plus significative pour expliquer la présence de nerprun bourdaine était la densité du peuplement, ce qui suggère que l’ouverture de la couverture forestière pourrait favoriser l’envahissement. Néanmoins, les résultats tendent à démontrer que le nerprun bourdaine est une espèce «généraliste» qui s’adapte bien à plusieurs conditions environnementales.
Glossy buckthorn (Rhamnus frangula L.) is an exotic species invading many areas in southern of Quebec, particularly in the Eastern Townships. Currently, we do not know very much about the species ecology and no thorough study of its distribution in temperate forest has been performed. Therefore, the first objective of the project was to map the spatial distribution of glossy buckthorn in two areas of the Eastern Townships, using remote sensing techniques. The second objective was to evaluate the environmental variables, or predictors, best explaining the presence of glossy buckthorn. The phenology of glossy buckthorn differs from most of the indigenous tree species found in this area because its leaves fall later in autumn. This characteristic allowed to map, using spectral unmixing, the probability of occurrence of glossy buckthorn, with temporal Landsat 8 (OLI) imagery data series. Glossy buckthorn coverage was calculated on 119 plots on the field. The resulting maps showed an agreement of 69% with field data. A SPOT-7 image, which has a finer resolution than Landsat 8 (OLI), was then used but it did not improve the quality of the map, since its acquisition date was not optimal, due to a lack of availability. Concerning the second objective of the research, the best variable explaining the presence of glossy buckthorn was stand density, which leads to believe that forest cover openings could ease the establishment of buckthorn. However, the results tend to show that glossy buckthorn is a generalist species, easily adapting to various environmental conditions.
