| 摘要 |
The invention relates to a process for obtaining plant ceramides, and specifically socalled simple ceramides corresponding to general formula (1) apt for direct entry into the lipidic composition of the outermost layer of the skin known as the "stratum corneum". The invention further relates to the composition thus obtained. The process consists in submitting the backberry leaf (morus alba) to extraction using a solvent, notably one of the solvents of the solvent group comprising liquid carbonic anhydride (C02), by applying the so-called supercritical CO2 method, followed by the mixture of chloroform and methanol according to the so-called FOLCH method. The composition proposed by the invention has particularly advantageous uses in the manufacture of dermatological products, of which the composition may be considered either as the raw material and active element, or as is for use as a dermatological product. |
