Determinação de aflatoxina B1 em pimenta (Piper nigrum L.) e orégano (Origanum vulgare L.) por cromatografia em camada delgada e densitometria

Abstract: Recebido em 8/1/07; aceito em 6/9/07; publicado na web em 10/3/08 DETERMINATION OF AFLATOXIN B 1 IN PEPPER (Piper nigrum L.) AND OREGANO (Origanum vulgare L.) BY THIN-LAYER CHROMATOGRAPHY AND DENSITOMETRY. An analytical study based on extraction with methanol-water, immunoaffinity cleanup and separation, identification and quantification of aflatoxin B 1 by thin-layer chromatography, in ground black and white pepper and oregano was carried out. Validation of the applied methodology was done through accuracy an… Show more

“…In Brazil, this species presents several utilities, being a widely consumed spice; however, the tropical climate of the country favors the development of fungi of the type Aspergillus spp. which produce mycotoxins detected on the grain, such as the aflatoxin B 1 , causing a great problem for being a powerful hepatocarcinogen described in mammals, and is classified in the Group 1 (carcinogenic to humans) by the International Agency of Research on Cancer (Prado et al, 2008). Other utilities are attributed to the black pepper, such as being a larvicide to the Aedes aegypti, of great importance for public health (Simas et al, 2007) and presents yet antibacterial property from its essence oil over food contaminants, in substitution to chemical additives (Trajano et al, 2009).…”

“…With scientific advances, this ancient practice gave way to synthetic drugs, falling into oblivion for more than 50 years (BUGNO et al, 2006), however, there has been a growing rediscovery of the value of medicinal plants not only because of some unforeseen side effects of many drugs artificial, but its high price, thus contributing to the resurgence of herbal therapy (through plants). As fungal organisms are widely distributed in the environment, may be present in soil, plants, decaying organic matter, water, air and dust, unprocessed products of animal or vegetable origin can become contaminated with a wide variety of fungal species and their toxic products (COSTA et al, 2009;PRADO et al, 2008;TASSANEEYAKUL et al, 2004). Knowing this, the consumption of natural drugs have made their use a public health problem because of the possibility of access to products without adequate conditions of use, without warranty of quality, safety and efficiency, fundamental to the recovery or preservation of health consumer.…”

“…a aflatoxina B1 (aFB1) está epidemiologicamente associada à alta incidência de câncer hepático, sobretudo em países tropicais (CIB 2004). Dada a importância da exposição humana a este tipo de aflatoxina para a saúde pública e às condições climáticas do Brasil, que favorecem a multiplicação de fungos e a produção de micotoxinas, é necessário um constante monitoramento da qualidade dos alimentos oferecidos para os consumidores (Prado et al 2008). estes mesmos autores afirmam que dentre as micotoxinas, as aflatoxinas (B1, B2, g1 e g2) representam a principal classe e são produzidas principalmente por Aspergillus flavus e por Aspergillus parasiticus.…”
