QUANTITATIVE DETERMINATION OF HYPERFORIN DERIVATIVES IN THE HERB OF HYPERICUM PER-FORATUM
Abstract
The way of determination of spectrophotometric method of hyperforin derivatives in the herb of Hypericum perforatum was developed. The relative error of determination doesn´t exceed 1,5%. It is shown that hyperforin derivatives are practically absent in the herb of Hypericum maculatum (this is different kind of Hypericum allowed for use), which causes its lower antimicrobial activity in comparison with Hypericum perforatum. Hyperforin derivatives are localized predominatly in the flowers of Hypericum perforatum.Downloads
