Complexes of saponins and their aglycons with phospholipids and pharmaceutical and cosmetic compositions containing them

Abstract

Complexes of saponins from Centella asiatica, terminalia sp. and Terminalia sericea and relevant aglycons with phospholipids are described. The saponins may be asiaticoside, madecassicoside and sericoside. The molar ratio of phospholipids to saponins is from 0.5 to 2. The phospholipids are selected from the group consisting of soy lecithins, phospholipids from bovine or swine brain or cutis, phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine in which the acyl groups can be the same or different and are mostly derived from palmitic, stearic, oleic, linoleic, linolenic acids. Pharmaceutical compositions and the method of treatment are also described.
