Chemical composition of the essential oils (EO) Pelargonium graveolens, Leptospermum petersonii and Cymbopogon martinii var. motia, absolute Rosa centifolia their bioactivity were examined. Major compounds in P. graveolens EO monoterpene alcohols citronellol, geraniol linalool; L. aldehydes geranial, neral citronellal; C. martiniii motia alcohol ester geranyl acetate, while R. aromatic 2-phenyl...

Recently, there has been a growing interest in research on nanofibrous scaffolds developed by electrospinning bioactive plant extracts. In this study, the extract material obtained from medicinal Inula graveolens (L.) was loaded polycaprolactone (PCL) electrospun polymeric nanofibers. The combined mixture prepared 5% of I. at 8% concentration and under optimal conditions. chemical analysis, mor...

Eight plant essential oils were extracted and tested for their efficiency as natural insecticides against the cotton mealybug, P. solenopsis (Tinsley). In-vitro bioassay, contact toxicity of to adult females 2nd instar nymphs was determined. Also, repellence activity tested. The most effective oil female’s after 72 hrs application L. nobilis followed by Apium graveolens, M. longifolia, C. artic...

We characterize the "sequence landscapes" in several simple, heteropolymer models of proteins by examining their mutation properties. Using an efficient flat-histogram Monte Carlo search method, our approach involves determining the distribution in energy of all sequences of a given length when threaded through a common backbone. These calculations are performed for a number of Protein Data Ban...

indian meal moth, plodia interpunctella hubner is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repellent activity of 18 p...

background & aim: in recent years using from plant product has been considered wildly as main factor for preventing pathogenic diseases cassed by attacking viruses, bacteria, fungi and parasites. there are some funguses which could be the factors for affliction of some diseases in human, plants and animals. plant extracts are those which could act and be used as preventing from these diseas...

The objective of this study was to evaluate the potential toxicity methanolic extracts Pinus roxburghii branch (P. roxburghii) and Nauplius graveolens (N. graveolens). Single oral dosage administered male mice at increasing concentrations 100, 250,500,1000 2000 mg/kg body weight assess median LD50, which causes death 50% (one half) mice. Blood samples were collected end 14 day toxicological tri...

Rutacridone, 1-hydroxy-A-methylacridone, and l-hydroxy-3-methoxy-A-methylacridone have been isolated for the first time from callus cultures, which had been obtained from meristematic stem cells of Ruta graveolens L. The alkaloids were identified by co-chromatography with authentic compounds, by IR spectra, and by electronic spectra before and after addition of A1C13 . The use of the bathochrom...
