Enantioselective hydrolysis of bromo- and methoxy-substituted 1-phenylethanol acetates was conducted using comminuted carrot (Daucus carota L.) and celeriac (Apium graveolens L. var. rapaceum) roots. Hydrolysis of the acetates led to alcohols, preferentially to R-(+)-enantiomers. Efficiencies of both reactions - hydrolysis of the acetates with an electron-donating methoxy group and oxidation of...

The volatile oils of black pepper [Piper nigrum L. (Piperaceae)], clove [Syzygium aromaticum (L.) Merr. & Perry (Myrtaceae)], geranium [Pelargonium graveolens L'Herit (Geraniaceae)], nutmeg [Myristica fragrans Houtt. (Myristicaceae), oregano [Origanum vulgare ssp. hirtum (Link) Letsw. (Lamiaceae)] and thyme [Thymus vulgaris L. (Lamiaceae)] were assessed for antibacterial activity against 25 dif...

This Commentary discusses the work of Neudecker et al. in this issue of the Biochemical Journal in which site-directed mutagenesis and NMR spectroscopy have been used to analyse in detail the IgE-binding capacity of two cross-reactive allergens: Apg1.0101 from celery ( Apium graveolens ) and Pru av 1 from cherry ( Prunus avium ), which are both members of the pathogenesis-related allergen famil...

Two S-adenosyl-L-methionine:furanocoumarin O-methyltransferases of R. graveolens, acting at the 5- and 8-hydroxyl of the psoralen nucleus, were completely resolved by adsorption on a general affinity ligand, 5-(3-carboxypropanamido) xanthotoxin, followed by specific desorption by bergaptol and xanthotoxol, respectively. The 5-O-methyltransferase was purified 450-fold by this procedure, the 8-O-...

Antimicrobial screening against selected Gram-positive and Gram-negative bacteria, yeasts, mold, as well as plant pathogenic fungi, with emphasis on method optimization was carried out on methanol extracts prepared from seven plants grown in Finland. Sensitivity to the extracts was found to vary considerably among the micro-organisms, the extract from Petroselinum crispum and Ruta graveolens sh...

A celery petiole phloem cDNA library was constructed and used to identify a cDNA that gives Saccharomyces cerevisiae cells the ability to grow on mannitol and transport radiolabeled mannitol in a manner consistent with a proton symport mechanism. This cDNA was named AgMaT1 (Apium graveolens mannitol transporter 1). The expression profile in source leaves and phloem was in agreement with a role ...

A young lady applied herbal mask of common rue (Ruta graveolens) onto her face. After that, she took a nap on a balcony in the full sun. An hour later, she woke up with a burning sensation, erythema and oedema of the skin. A few hours later, painful erythema and oedema developed. Subsequently, she developed a bullous reaction, which became superinfected in the following days. After treatment of...

introduction: dill (anethum graveolens), a herb from from umbelliferae, is used traditionally to treat convulsion and increasing milk production. its antimicrobial, antihyperlipidaemic, anti-hypercholesteroaemic effects and gastric acid secretion reducing effect have been reported. the spasmolytic effect of dill fruit on rat uterus has also been shown recently. the aim of present study was to i...
