| Popis: | No começo de um levantamento da composição química de frutos e legumes da região amazônica, adaptou-se métodos analíticos para a determinação de pro-vitamina A (β -caroteno), vitamina C (ácido ascórbico) e vitamina E (tocoferol), através da cromatografia líquida de alta pressão (HPLC). As primeiras análises indicam como excelentes fontes de β- caroteno, Mauritia flexuosa L., Astrocaryum tucuma Mart., e Cucurbita pepo L., de ácido ascórbico, Theobroma grandiflorum (Culis ex Spreng.) e de vitamina E, Mauritia flexuosa L. e Euterpe oleracea Mart. At the beginning of on inventory of the chemical composition of regional fruits and vegetables of the Amazon, analytical methods were adapted for the high performance liquid chromatography (HPLC) determination of pro-vitamin A (β-carotene), vitamin C (ascorbic acid) and vitamin E (tocopherol) The first analyses indicate as excellent sources of β-carotene, Mauritia flexuosa L., Astrocaryum tucuma Mart. and Cucurbita pepa L.; of asco bic acid Theobroma grandiflorum (Culis ex Spreng.) Schum. and Gnetum paniculatum Spr. ex Ben. th. and of vitamin E, Mauritia flexuosa L. and Euterpe oleracea Mart. |
