High yield extraction method for and products of Corydalis plants

Abstract

A method of extracting a C. yanhusuo plant comprising the steps of harvesting and drying the plant; extracting the alkaloids from the plant in a solvent; filtering the solvent—C. yanhusuo plant mixture to remove the solvent and extracted alkaloids from a spent plant matter; drying the spent plant matter; purifying and separating the extracted alkaloids from the solvent; and mixing the purified alkaloids back into the dried spent plant matter. Also, products of the method include vaporizing liquids, medicinal compositions, kief compositions, rolling papers, and filters for tobacco and vaporizing equipment comprising the mixture of the purified alkaloids and the dried spent plant matter produced according to the method. Further, a C. yanhusuo plant having a total alkaloid content of about 3%, of which 97% of the total alkaloid content is bulbocapnine and tetrahydropalmatine (THP).
