This recommended practice enables the quantification of volatile compounds in flavourings to be made by gas chromatography with flame-ionization detection, without having authentic compounds available, and also in many cases it can avoid time-consumi

Many flavour regulations around the world contain a list of so-called ‘restricted substances’ (RS), i.e. substances that occur naturally in source materials for flavourings and food ingredients with flavouring properties, but whose presence in ce

Simultaneous distillation-extraction (SDE) combines, in a single step, hydro-distillation of volatiles from a sample with continuous solvent extraction of the solutes dissolved in the aqueous distillate. The solvent extract containing the isolated fl

The synthesis and characterization of a number of macrolides, structurally related with erythromycin, is described. These derivatives have been previously investigated for their ability to induce contractions and to displace bound motilin in rabbit d

ERYTHROMYCIN A appears to be a motilin agonist, although motilin (a peptide) and erythromycin A (a 14-member macrolide antibiotic carrying two sugar substituents) are structurally totally unrelated. To obtain information concerning the structural req

A method is described for the determination of erythromycin estolate by liquid chromatography. A C18 reversed-phase column (25 x 0.46 cm i.d.) was used with acetonitrile-tetrabutylammonium sulphate (pH 6.5, 0.2 M)-phosphate buffer (pH 6.5, 0.2 M)-wat

A column-switching technique is described for LC of erythromycin. The method allows, in about 1 h, the separation of erythromycin A from all its known potential impurities, except erythromycin D, which is a minor impurity. The switching technique com

A method is described for the determination of erythromycin ethylsuccinate by liquid chromatography. A C18 reversed-phase column (25 cm x 4.6 mm I.D.) was used with acetonitrile-0.2 M tetrabutylammonium sulphate (pH 6.5)-0.2 M phosphate buffer (pH 6.
