ABSTRACT

Objetivou-se verificar a qualidade de ovos brancos de acordo com os aspectos internos e externos comercializados em diferentes estabelecimentos do município de Paragominas - PA. Os ovos foram coletados de aleatoriamente em diferentes pontos comerciais. As análises consideradas no estudo, foi de: integridade e aparência da casca e peso do ovo, altura da câmara de ar, peso, altura e diâmetro da gema para o cálculo de índice da gema, altura e peso do albúmen e cor da gema. Os dados foram submetidos à análise de variância e ao teste de Tukey. Os ovos dos grandes supermercados apresentaram melhores índices de qualidade interna e os piores resultados quanto a peso, trincas visíveis e sujeiras. Os ovos de pequenos supermercados apresentaram o maior índice de trincas não visíveis e os de médio porte os menores índices de sujeiras e trincas.

ABSTRACT

INTRODUCTION: There are few studies reporting the antifungal activities of Lippia alba extracts. METHODS: A broth microdilution assay was used to evaluate the antifungal effects of Lippia alba extracts against seven yeast species of Candida and Cryptococcus. The butanol fraction was investigated by gas chromatography-mass spectrometry. RESULTS: The butanol fraction showed the highest activity against Candida glabrata. The fraction also acted synergistically with itraconazole and fluconazole against C. glabrata. The dominant compounds in the butanol fraction were 2,2,5-trimethyl-3,4-hexanedione, 3,5-dimethyl-4-octanone and hexadecane. CONCLUSIONS: The butanol fraction may be a good candidate in the search for new drugs from natural products with antifungal activity.
