Processes for preparing extracts of natural products such as plant material, and for preparing purified extracts from crude extracts of natural products, by extraction with hot gas. Apparatus suitable for use in preparing extracts of natural products are also described.

Processes and apparatus for extraction of active substances and enriched extracts from natural products

The invention relates to the extraction of pharmaceutically active components from plant materials, and more particularly to the preparation of a botanical drug substance (BDS) for incorporation in to a medicament. It also relates to a BDS of given purity, for use in pharmaceutical formulations. In particular it relates to BDS comprising cannabinoids obtained by extraction from

Extraction of pharmaceutically active components from plant materials

A device for vaporizing a medicament (). The device comprises a resistive element () on which the medicament is deposited. The device also comprises a source of electrical power which can be connected across the resistive element to vaporize the medicament. The element is configured to provide a central cool region () on which the medicament is deposited and a relatively hotter region () surrounding the cool region. Through holes () are also provided. The resistive element may be a mesh, foil or a tile on which a resistive pattern is deposited.
