Edelweiss Phenylpropanoids

Leontopodic Acids

 

Edelweiss – Leontopodium alpinum – is the mythic flower sparely distributed in the heights of Asian and Europe mountains. It grows at high altitudes of 1800-3000 meters in inacessible areas and it is protected in many countries. From the early 2010’s is has been recognized as a very valuable source of skin anti-aging principles by the cosmetic industry. Cultures have been developped, mainly in Valais area (Switzerland), making the herb and its extracts available for commercial applications. Also ingredients based on cell cultures are now proposed for formulation.

The main actives substances of its hydro-alcoholic extracts are Leontopodic acids A and B, new and very specific phenylpropanoids identified for the first time in 2005 (ref. 1). The plant is also rich in Chlorogenic acid and 3,5-Di-O-caffeoylquinic acid, another typical marker of this specy.

For the first time on the market, Extrasynthese has made available Leontopodic Acids A and B as analytical standards, to allow the industry and research community to deepen its knowlegde in these fascinating substances.
