An essential step in the characterization of liposomal systems as drug vectors is one that analyzes the release rate of incorporated substances. In vitro release tests are used not only to characterize various formulations of therapeutic use, but also to predict their in vivo behavior. The objective of this work was to formulate and in vitro characterize hydrogels containing liposomal suspensio...

As a result of his botanical explorations in northern Australia, Ferdinand von Mueller named several Cucurbitaceae that molecular data now show to be distinct, requiring their resurrection from unjustified synonymy. We here describe and illustrate Luffa saccata F. Muell. ex I.Telford, validating a manuscript name listed under Luffa graveolens Roxb. since 1859, and we lectotypify Cucumis picroca...

The biosynthesis of some furocoumarins present in Ruta graveolens has been studied administering labeled psoralen, xanthotoxin, rutaretin, marmesin and 7-hydroxycoumarin-derivatives. The results obtained indicate that the biosynthetic pathway involves not only psoralen, but also xanthotoxin and bergapten, by means of methoxylation or demethoxylation reactions. Moreover results achieved from adm...

Among hundreds of formulae of Chinese herbal prescriptions and recently extracted active components from the herbs, some of which had demonstrated their functions on nervous system. For the last decade or more, Gingko biloba and Polygala tenuifolia were widely studied for their beneficial effects against damage to the brain. Two compounds extracted from Apium graveolens and Rhizoma coptidis, bu...

Acridone synthase has been purified from cell suspension cultures of Ruta graveolens using a combination of gel filtration and ion exchange chromatography. The purified enzyme has an apparent molecular weight of 69 kDa on gel filtration and a subunit structure on SDS-PAGE of 40 kDa. The apparent Km-values are 10.64 microM and 32.8 microM for N-methylanthraniloyl-CoA and malonyl-CoA, respectivel...

This study presents a preliminary data of occurrence of elemental concentration in medicinal plants i.e Apium graveolens (seed), Sida cordifolia (root), Solanum surattense (whole plant), Tribulus terrestris(fruit) and Withania somnifera (root) used in Ayurveda, using Atomic absorption spectrometer (AAS) following standard procedures. The elemental concentration i.e. Mn, Na, K, Cl, Ca, Cr, Co, C...

A study to reveal spatial distribution patterns in four characteristic dry forest tree species was undertaken in six one-hectare plots in the Cerros de Amotape National Park, northwestern Peru. The modified Ripley’s K statistic was used. Eriotheca ruizii (K. Schum.) A. Robyns (Bombacaceae), Bursera graveolens (Kunth) Triana & Planch. (Burseraceae), Caesalpinia glabrata Kunth (Leguminosae) and C...

background: natural products are proved to play a good role as an alternative to synthetic chemicals in clinical conditions. previous studies showed that pelargonium graveolens has anti-inflammatory and antifungal activity against candida albicans . the aim of this study was to evaluate the efficacy of essential oil of pelargonium graveolens in the treatment of denture stomatitis . materials an...

Heterotrophic cell suspension cultures of Ruta graveolens were established by reversion of photom ixotrophic cultures without any change in the chemical composition of the growth medium. The heterotrophic cultures were qualitatively and quantitatively analyzed by gaschromatography and mass spectroscopy for volatile compounds. The terpenoid hydrocarbons geijerene and pregeijerene, C6-C8 ketones,...

Methods Immunoblots were performed with extracts of celeriac and celery stalks using sera of A. graveolens sensitized patients from Austria (n=23). Purified allergens were obtained from natural source (celeriac) or produced as recombinant proteins in E. coli and IgE reactivity to rApi g 1, rApi g 2, nApi g 5, and nApi g 6 was tested in ELISA. IgE cross-inhibition assays were performed with puri...
