Anti-tumor effective component of Hedyotis diffusa, preparation method therefor and use thereof

Abstract

The present invention relates to the field of medicines, in particular to an anti-tumor effective component of Hedyotis diffusa, a preparation method therefor and the use thereof. Provided in the present invention is the use of one or a combination of kaempferol-3-O-[2-O-(6-O-E-feruloyl)-β-D-glucopyranose]-β-D-pyranose and E-6-O-p-coumaroylpaederoside methyl ester in tumor resistance or the preparation of an anti-tumor drug. The research of the present invention has shown that both a kaempferol-3-O-[2-O-(6-O-E-feruloyl)-β-D-glucopyranose]-β-D-pyranose compound monomer and an E-6-O-p-coumaroylpaederoside methyl ester compound monomer have very strong anti-tumor activity. In the in-vivo anti-tumor activity research, the inhibition rates thereof can reach 48.97% and 45.96%, respectively; and when both are combined to inhibit tumor cells, the research reveals that the two monomers have an obvious effect of synergistically inhibiting tumors.
