Process for extraction and standardization of pharmaceutical quality tinctures and extracts from herbal products

摘要

The present invention relates generally to herbal materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. Particularly, the present invention relates generally to Hydrstatis canadensis (goldenseal) materials and methods for making such materials in medicinally useful and pharmaceutically acceptable forms. More particularly, the present invention relates a process which allows the precise standardization of at least two marker compounds, berberine and hydrastine, in both hydro-alcoholic tinctures and solid extracts in the processing of goldenseal materials to produce extracts which qualify as pharmaceutical grade compositions which are suitable for use in clinical or veterinary settings to treat and/or ameliorate diseases, disorders or conditions.
