Process for the preparation of a stable, homogeneous, extract free or nearly free from secondary reaction products |
摘要 |
A process for the preparation of a stable, homogenous extract of plants or plant parts is disclosed. The process comprises mixing and extracting the plants or plant parts charged in a fresh and/or dried state with at least one solvent and at least one agent (having various disclosed properties), then filtering insoluble compounds to obtain a filtrate which is substantially free of secondary reaction products and contains a native compound mixture. The filtrate is concentrated to a spissum extract and the pressure used for the concentration is adjusted according to the vapor pressure of the solvent(s).
