摘要

A method for standardization of herb horsetail (Equisetum arvense L.) in multi-herbal mixtures using HPLC method, where the herb of horsetail plant in mixtures is determined by chromatography in gradient mode using aqueous mobile phases and atsetonitryl reverse-phase column with pre-treatment samples using solid-phase extraction in the presence of di-E-cofeyl mesotartaric acid.
