Determination of patulin by reversed-phase high-performance liquid chromatography with extraction by diphasic dialysis

Abstract: A simple and economical method has been developed for the determination of patulin in apple juice. The sample is extracted with ethyl acetate in a diphasic dialysis system, and the extract is cleaned up by elution from a Sep-Pak cartridge. Patulin is detected and determined by reversed-phase high-performance liquid chromatography using a Novapak C18 column and an ultraviolet detector. The lower detection limit is 1 microgram l-1 and the recovery is 85% at the 20 micrograms l-1 level.

“…The most widely used sample preparation technique has been solvent extraction. Recently, some solid phase extraction (SPE) protocols for purification of patulin from apple juice have been reported [29][30][31][32][33][34]. However, typical SPE sorbents lack selectivity and this constitutes a problem when a selective extraction from a complex matrix has to be performed.…”

“…A variety of methods of analysis for PAT in fruit and fruit juice has been developed: TLC (Prieta et al, 1992;AOAC,1995;Vero et al, 1999), HPLC (Prieta et al, 1993;Rovira et al, 1993;Bartolomé et al, 1994;Gö kmen and Acar, 1999;Trucksess and Tang, 1999;Eisele and Gibson, 2003;Gö kmen et al, 2005;Iha and Sabino, 2005), GC (Tarter and Scott, 1991), GC/MS (Llovera et al, 1999;Sheu and Shyu, 1999;Roach et al, 2000;Rupp and Turnipseed, 2000;Tabata et al, 2004), LC/MS (Takino et al, 2003;Ito et al, 2004). Tsao and Zhou (2000) developed a method of capillary electrophoresis (CE) and Sewram et al (2000) a method of LC/MS-MS.…”

“…Isso também afeta a transcrição e a tradução, tendo um efeito direto no DNA (RILEY & SHOWKER, 1991). Essa propriedade de inativar enzimas ocorre principalmente como uma conseqüência da formação de ligações covalentes com células essenciais contendo grupos sulfidril ou tiol (SH) (ARAFAT & MUSA, 1995;FLIEGE & METZLER, 1999).…”

“…A detecção e quantificação de patulina nas placas de sílica-gel são feitas pela formação de derivados fluorescentes, por meio do borrifamento de 3-metilbenzotiazolinona hidrazona (MBTH), em que se obtém um limite de detecção (LD) de 20µg L -1 (AOAC, 2000), ou por meio da exposição das placas de CCD a vapores de amônia e quantificação por fluorodensitometria com LD de 100µg L -1 (DURAKOVIC et al, 1993). A diálise bifásica foi utilizada para extração de patulina, e a determinação da concentração da micotoxina foi feita por CCD (PRIETA et al, 1992) e CLAE (PRIETA et al, 1993). Nessa técnica, a membrana contendo o solvente orgânico é agitada na matriz aquosa até que os analitos de interesse, que possuem baixo peso molecular, passem através da membrana, enquanto que as demais substâncias de maior peso molecular ficam retidas na fase aquosa.…”
