چکیده
Amostras de ceras do ninho e da própolis de Apis mellifera foram analisadas. Observou-se a predominância de ésteres, seguidos de hidrocarbonetos. Os constituintes foram identificados por cromatografia a gás/espectrometria de massas. Amplas variações foram observadas nos padrões de hidrocarbonetos e dos ácidos e álcoois de ésteres. As cadeias carbônicas dos hidrocarbonetos abrangem a faixa C23 C35, com o predomínio de C27 e C31. O principal ácido carboxílico foi C16:0, seguido de C18:0 e C18:1. Os principais álcoois constituintes de ésteres foram homólogos saturados normais, na faixa C24 C32, C30 sendo o mais abundante, seguido de C24. Não foram observadas diferenças que permitam distinção, o que sugere uma origem comum para ambas as fontes de cera.
