This study evaluates the antibacterial activity of the Copaifera duckei Dwyer oleoresin and two isolated compounds [eperu-8(20)-15,18-dioic acid and polyalthic acid] against bacteria involved in primary endodontic infections and dental caries and assesses the cytotoxic effect of these substances against a normal cell line. MIC and MBC assays pointed out the most promising metabolites for furthe...

The aim of the present study was to assess the clinical efficacy of a one week/month treatment with a phytocompound with antimycotic properties (K-712, with following 100 mg composition: 10 mg of oleoresin from Pseudowintera colorata at 30 percent concentration in Polygodial together with trace amounts of Olea europea) in recurrent vulvo-vaginal candidiasis (RVVC), as compared to once a week tr...

4apillary gas chromatography and mass spectrometry were used to quantify the amounts of Eand Zchalcogran and methyl (E,Z)-2,4-decadienoate (E,Z-MD), pheromone synergists of the bark beetle Pitygenes chalcographus (Coleoptera: Scolytidae). Males were exposed or not to vapours of host (Norway spruce, Picea abies) oleoresin or allowed to feed in host logs prior to extraction of body parts and hind...

Cytochrome P450 monooxygenases (P450s) are important enzymes for generating some of the enormous structural diversity of plant terpenoid secondary metabolites. In conifers, P450s are involved in the formation of a suite of diterpene resin acids (DRAs). Despite their important role in constitutive and induced oleoresin defense, a P450 gene of DRA formation has not yet been identified. By using p...

Herbal medicine is still the mainstay of about 70-80% of world population, main ly in the developing countries, for primary health care because of better cultural acceptability, better compatibility with human body with lesser side effects. Acacia nilotica is also a popular ornamental avenue tree in India. This review aimed at revealing brief account of plant part used, mode of admin istration,...

Curcumin is coming from the Curcuma longa which gives golden color and have the biological importance. As per the survey it is water insoluble, the poor solubility and wettability of curcumin leads to poor dissolution and hence shows poor bioavailability. The present study is aimed at increasing solubility of drug using solid dispersion technique. The solid binary systems were prepared using di...

The induction of a 15 to 20 fold increase in oleoresin content of resin soaked xylem in paraquat treated pine stems raises many intriguing questions of a physiological nature. Our knowledge of stem anatomy and physiology of oleoresin formation in pines appears to exclude the possibility that resin soaking results from long range transport of oleoresin via vertical resin ducts to resin soaked ar...

Certain plant extracts are bioactive substances of some foods or traditional herbs, known to possess antioxidant, antibacterial, and perhaps immunoregulatory effects. This study investigated the in vitro anti-infl ammatory effects of 7 plant extracts (anethol, capsicum oleoresin, carvacrol, cinnamaldehyde, eugenol, garlicon, and turmeric oleoresin) on porcine alveolar macrophages collected from...

The oleoresin of the copaiba tree (Copaifera sp., Fabaceae) is traditionally used in Brazilian herbal medicine to treat a variety of illnesses and symptoms. This study, conducted according to the OECD Guideline 414, provides data on the developmental toxicity of oleoresin from C. reticulata (COPA-R) in rats. Pregnant Wistar rats (25 per dose group) were treated by gavage with COPA-R (0, 500, 10...

Approximately 90% of fine aerosol in the Midwestern United States has a regional component with a sizable fraction attributed to secondary production of organic aerosol (SOA). The Ozark Forest is an important source of biogenic SOA precursors like isoprene (> 150 mg m-2 d-1), monoterpenes (10-40 mg m-2 d-1), and sesquiterpenes (1040 mg m-2d-1). Anthropogenic sources include secondary sulfate an...
