Goldenseal (Hydrastis canadensis)
Goldenseal Metabolomics CSV JSON

LC-MS metablomics and composite score analysis [1,2] was used to compare the chemical composition of 35 commercial H. canadensis samples. A single sample (dried Hydrastis canadensis room material, arbitrarily identified as GS-16) was chosen for use in pharmacology studies based on its similarity to authentic reference standards and to other commercially used goldenseal supplements.
