Our passion is the chemistry of plants !
Our mission is to manufacture, qualify and sell phytochemical substances as reference materials and analytical standards on a worldwide basis. For more than 30 years, we are experts in extraction, synthesis, biosynthesis, purification and analytical technologies, from which we have developed a more than 1000 substances catalog, we supply to all academic, regulatory, agricultural and industrial bodies dealing with plants and herbal products. From year to year we improve our technologies and we complete our unique catalog of anthocyanins, flavonoids,coumarins and other phenylpropanoids, polyphenols, carotenoids, terpenes and saponins, alkaloids, lipids like phytosterols or tocopherols, and oligosaccharides.
