摘要

The present invention regards a process for extracting flowering tops of Calendula officinalis comprising the extraction with carbon dioxide in supercritical phase at high temperature and pressures, in order to obtain two extracts which, when mixed together in suitable weight ratios, constitute a total extract enriched with calenduladiol, arnidiol and faradiol esters with myristic, lauric and/or palmitic acid. This total extract can be conveniently used for preparing topical formulations for cosmetic or pharmaceutical use.
