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

Abstract

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 ) shows limited growth inhibitory effect on the cancer cell lines examined. It is concluded that the cytotoxic activity of cactus pear cladodes is attributed to phenolic compounds especially the flavonoids. It is recommended that population at risk utilize these materials as preventative natural dietary supplements against cancer.

Seasonal variability of phenolic compounds and antioxidant activity in prickly pear cladodes of Opuntia and Nopalea genres

“…After collection, the material was cleaned, weighed, cut into small pieces (2-3 cm long) and dried in a forced-air oven at 55 °C, where it remained for 72 hs until constant weight. The dried (Alves et al, 2016b).…”

“…The extraction of the dry and crushed material (10 g) was performed with 95% ethanol at room temperature, covering the entire sample with the solvent following methodologies described in Alves et al (2016b).…”

“…For the identification of alkaloids, steroids, tannins, flavonoids and saponins was used sample of crude ethanolic extract (1 mg) following methodologies described in Alves et al (2016b).…”

Effect of feeding on different levels of crushed cactus in total mixed rations on fattening performance, carcass characteristics, and meat quality of Awassi sheep

“…There are different factors which determine the nutritive value of cactus viz. season, age, variety, harvesting, and ecology (Dubeux et al 2010;Alves et al 2016;Souza et al 2017;Pessoa et al 2020). In dry season it regarded as an important source of energy and water for animals, particularly ruminants (Costa et al 2009).…”
