“…8) It is because of their edible fruit that they are known in vernacular as prickly pears. Pharmacological evaluation of Opuntia has shown its efficacy as antihyperlipidemic, 9) antiatherosclerotic, 10) antiviral, 11) anti-inflammatory, 12) antidiabetic, 13) antioxidant and antiulcerogenic 14) agent. It has also been reported to protect nerve cells and used for the treatment of Alzheimer's disease, Parkinson's disease and stroke.…”

Methanolic extract of Opuntia dillenii cladodes and its pure compound a a-pyrone glycoside, opuntioside-I showed potent hypotensive activity in normotensive rats. Both the extract and opuntioside-I showed comparable effect of 44-54% fall in Mean Arterial Blood Pressure (MABP) at the dose of 10 mg/kg. No mortality was observed in rats even at the doses of 1000 mg/kg/d and 900 mg/kg/d per oral of extract and opuntioside-I respectively. However, histopathology revealed adverse effects of high doses on liver and spleen of the experimental animals.

“…Plants have been used for centuries in the medical practices mostly in therapy of diverse pathologies [20] . Nopal is widely used in Mexico as a treatment for glucose control [21] and is known in the United States as prickly pear cactus. N. cochenillifera pads are rich in vitamin A and have been used for headaches, eye troubles and insomnia if consumed as a tea [21] .…”

“…However, important validation of its antimicrobial properties has not been fully determined. Some reports have shown inhibition of herpes simplex virus type 1 infection by N. cochenillifera [17] and antiviral activity of Opuntia streptacantha [21] . In our study, we showed that this cactus possesses antibiotic activity against Candida albicans, Escherichia coli and Salmonella enterica var.…”

Effectiveness of botanical treatments has been recognized by many, but scientific validation on the beneficial use of plants is scarce. Nopalea pads are probably native to Mexico or Central America and are used for human consumption and for medicinal purposes. In this study, in vitro antibacterial and antifungal activities of fresh and dried Nopalea cochenillifera (NC) were investigated. MICs of fresh NC hexanic, chloroformic and ethanolic fractions against C. albicans were 250, 250 and 3.9 µg mL 1 respectively; MICs of fresh NC against Salmonella enterica var. thyphimurium were 15.6, 62.5 and 3.9 µg mL 1 respectively; and MICs of fresh NC against Escherichia coli were 500, NA (no activity) and 3.9 µg mL 1 respectively. In addition, MICs of dried NC hexanic, chloroformic and ethanolic fractions against C. albicans were 31.2, 31.2 and 3.9 µg mL 1 respectively; MICs of dried NC against Salmonella enterica var. thyphimurium were 15.6, NA and 3.9 µg mL 1 respectively; and MICs of dried NC against Escherichia coli were NA, 62.5 µg mL 1 and NA respectively. The relevance of using fresh versus dried Nopalea cochenillifera pad extracts against in vitro microbial growth is discussed.

The technological and biomedical applications of low toxicity and eco-friendly organic compounds are nowadays increasingly attracting the attention of researchers in nanoscience, who are aiming for more biocompatible and nanostructured systems for their application in antineoplastic therapies. This study presents the significance of "green components" in the production of graphene, metallic, and semiconductor nanoparticles, due to their antioxidant and antitumor properties. The formation of nanostructures is caused during green synthesis methods by organic molecules or carboxylic acid groups present in some plant extracts; for this reason, we include here a recapitulation and analysis of the role of carboxylic acids in those systems (organic). Furthermore, we propose the use of the extract from Opuntia ficus-indica cladodes to obtain metallic and carbon nanostructures, as an alternative biosynthesis method for the development of future nanobiotechnological applications.
