Abstract:
Endogenous levels of tocopherols and ascorbic acid were quantified by high-performance liquid chromatography (HPLC) during fruit ripening of New Mexican-type chile peppers (Capsicum annuum L.). gamma-Tocopherol (gamma-toc) was present in seeds, while alpha-tocopherol (alpha-toc) was present in the pericarp. gamma-Tocopherol content reached its maximum concentration in seeds from red, succulent fruit and then declined. alpha-Tocopherol increased from the green to dry red maturity stages. Cultivars differed for alpha-toe but not for gamma-toc contents. Ascorbic acid content increased after the green mature stage and peaked in red fruit with about 75% moisture content. Ascorbic acid was highest in the cultivars NuMex R Naky and Sandia.
