    摘要： The present invention relates to the preparation of a Cynara scolymus extract obtainable by fractioning on a resin. The process of the invention allows to obtain an extract, starting from the aerial parts of the plant Cynara scolymus, containing three classes of active principles, namely dicaffeoylquinic acids, luteolin and cynaropicrin glycosides, in a constant ratio. Cynaropicrin is stabilized by addition of precise amounts of sulfated amino acids or suitable thio-derivatives. These extracts have hypolipemizing, anti-dyspeptic and vascular anti-inflammatory activities. The extracts are mainly formulated in Enothera biennis oil or in oils rich in ω-3 and ω-6 acids which enhance the vascular activity.

    摘要： Process for removing pesticides from Ginkgo biloba extracts, which involves submitting an extract obtained by conventional methods to the following steps: a. Liquid-liquid extraction of the extract to obtain a medium polarity fraction containing ginkgo terpenes and pesticides not removable with hexane, and a high polarity fraction containing ginkgo flavone glycosides; b. crystallization from the medium polarity fraction obtained at step a) to give an intermediate with a ginkgolide content of not less than 50%; c. crystallization from the residual solution obtained at step b) to give an intermediate with a bilobalide content of not less than 50%; d. mixing of the high polarity fraction obtained at step a) with the ginkgo terpene intermediate and the bilobalide intermediate obtained at steps b) and c).
