Elaboration of the HPLC method for the phytochemical study of Hypericum perforatum L. species
The HPLC method with multiwavelength UV-VIS detection has been developed for the
quantification of pharmacologically active substances in herb of St. John’s Wort (Hypericum perforatum L.) and in extractive products. The procedure for preparation of raw material samples has been optimized, having in mind instability of some active substances in solutions. It was confirmed, that the greatest part of active substances can be found in flowers, smaller amount - in leaves, but stems are practically deprived them. |
