189 results about "Hypericin" patented technology

Hypericin is a naphthodianthrone, an anthraquinone derivative which, together with hyperforin, is one of the principal active constituents of Hypericum (Saint John's wort). Hypericin is believed to act as an antibiotic, antiviral and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine β-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine.

Process for preparing hypericum perforatum extract

The present invention relates to the preparation process of extract containing three active components including hypericin, Hyperforin and flavones in the total content not less than 50% from hypericum perforatum or other congeneric plant. The three active components are separated from the polar solvent extracted liquid via biphase extraction with non-polar solvent selected based on their difference in polarity. They are then purified separately based on their difference in acid-base property to obtain the extract A with high hypericin and flavones content and extract B with high Hyperforin content. The two extracts are merged through dissolution to obtain hypericum perforatum extract with total active component content not less than 50%. The extract has the obvious activity of resisting depression and may be used as the material of depression treating medicine or functional food.
