What is "Rosa Alba Leaf Cell Extract" and what is its utility?

Characterised by its lack of colour and simple petal crown, this hybrid rose has symbolised purity and innocence since ancient Greek times, when it was the flower of Aphrodite, the young goddess of beauty. According to some legends, it is the precursor to the red rose. For instance, it is said that during the Roman era, Venus pricked herself on the thorn of a white rose during a forest excursion, and her blood stained the petals of the flower, leading to the birth of the red rose.

Today, this ancient rose is cultivated in certain European countries, including France, for its cold resistance, its sweet and powerful fragrance, and for its essential oil; however, it is believed to still grow in the wild in Asia Minor.

The native plant cells are whole cells that are locally harvested from the plant. They are derived from a biotechnological process that respects the environment and biodiversity. This process takes place in several stages:

1. Sampling : taking a piece of the plant (leaf or flower);

2. Culture in vitro of the harvested plant piece : successive transplantations onto a fresh nutritive medium composed of water, minerals, sugar, and vitamins;

3. Elicitation : stimulation 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 extraction method allows for the preservation of all active molecules present in the plant cells, which gives this compound a complementary action against other plant extracts (vegetable oils, essential oils and hydrosols).
