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.

Abstract: Complexes of glycyrrhetinic acid with phospholipids are described in which the molar ratio of phospholipids to glycyrrhetinic acid 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. The phospholipid may be soy phosphatidylcholine or distearoylphosphatidylcholine. Pharmaceutical compositions and a method for producing anti-inflammatory, antiulcer and healing effects in an animal are also described.

Abstract: Complexes formed between aescin, cholesterol or .beta.-sitosterol and phospholipids are described. The molar ratio of phospholipids to aescin/.beta.-sitosterol or cholesterol is from 0.5 to 2. The phospholipids are selected from the group of soy or egg lecithins, phospholipids from bovine or swine brain or cutis, phosphatidylcholine, phospatidylserine, phosphatidylethanolamine in which the acyl groups may be the same or different and are mostly derived from palmitic, stearic, oleic, linoleic, linolenic acids, for instance, pharmaceutical compositions and a method for producing an anti-inflammatory effect in an animal are also described.
