Elicitation induced flavonoids, phenolic constituents, antioxidant and cytotoxic activities of Artemisia monosperma callus cultures

Artemisia monosperma (Delile) callus was induced using seedling explant cultured on Murashige and Skoog solid medium (M&S) supplemented with 1 mg/L naphthalene acetic acid (NAA) and 1 mg/L kinetin (Kn). Cultures were maintained on 2 mg/L 2,4-dichlorophenoxy acetic acid (2, 4- D) and 1 mg/L Kn and treated with different elicitors. Total flavonoids and phenolics were determined by aluminum chloride-potassium acetate...

Genetic diversity and seasonal chemical profile by 1H NMR and cytotoxic activity in Opuntia and Nopalea genres

The cactus pear (Opuntia spp.) is known to have bioactive compounds which work in the prevention of various diseases, especially cancer. The objectives of the study were to characterize the chemical profile and genetic diversity, through chromatic tests and 1H NMR, using multivariate analysis, and assess the cytotoxic potential of cactus pear varieties of Opuntia and Nopalea genera grown in the semi-arid region of...
