How are native nopal cells obtained?

The nopal, or prickly pear, belongs to the cactus family. Originating from central Mexico, this uniquely shaped cactus, characterised by its organisation into cladodes (or pads), appeared in the Old World in the 16th century and has particularly thrived around the Mediterranean basin. Today, the nopal is cultivated for its edible fruits, which have a multitude of culinary and medicinal uses, discovered by Mesoamerican populations as early as the 16th century. The nopal is thus associated with healing and antioxidant properties (due to the Vitamin E it contains). It is even considered a potential ally in the case of diabetes as it is believed to help reduce glucose and lipids in the blood.

Note : The Prickly Pear Cactus has been featured on the Mexican flag since the country's independence.

This refers to whole cells taken from specific areas of the plant. They are the result of a biotechnological process that follows several stages:

1. Selection of the Plant and Sampling : Taking a piece from the plant (leaves);

2. Culture In vitro of the harvested plant piece: Successive transfers onto a fresh nutritive medium composed of water, minerals, sugar, and vitamins;

3. Elicitation: Stimulation of cell culture through UV and visible light to produce metabolites (active molecules);

4. Rinsing : Removal of all traces of the nutrient medium ;

5. Cell Filtration ;

6. Sonication of cells and dispersion of the extract in sunflower oil.

This technique aims to replicate and multiply cells from cellular strains in a controlled environment. This process is not only beneficial for the ecosystem, but also allows for the preservation of all the plant's natural elements. Rich in essential amino acids, vitamins and minerals, the nopal native cells thus obtained have a high molecular richness that provides them with a complementary action against other plant extracts (vegetable oils and essential oils).
