Published: December 2014

Carotenoids and tocopherols are lipid secondary metabolites that play essential roles in plants. They are also relevant compounds from a nutritional standpoint and attract much attention due to their proposed antioxidant properties. In this chapter, methodologies for the extraction and HPLC analysis of these compounds are described as well as a widely used protocol to assess their antioxidant capacity.

Essential fatty acids (EFAs) in edible oils are crucial for human nutrition. However, their high unsaturation renders edible oils susceptible to oxidation during storage and processing. The addition of lipophilic antioxidants is an effective strategy to inhibit oxidation and safeguard the nutritional integrity of edible oils.

An experiment was performed to understand the effects of aluminium toxicity (AlCl·6HO) on Kachai lemon growth and development. The toxic effects of aluminium were assessed for 45 days in sand media. With untreated pots serving as the control, seedlings of 1 month old were exposed to three concentrations of AlCl·6HO: 300 μM, 600 μM and 900 μM.

Retinol, α-tocopherol and phylloquinone (vitamins A, E, and K) are presented in high concentrations within the chloroplast and leaves of most plants. They are fat-soluble vitamins and absorb similarly to other dietary lipids. Because the molecular mechanism of retinol, α-tocopherol, and phylloquinone absorption is still unknown, this work aims to investigate the distribution of these vitamins at the water/membrane interface using molecular dynamics (MD) simulations.
