Comparative Anti-Tumor Activity Study of Tartary Buckwheat Flavonoids and Amphibian Peptides

Abstract

In China, many kinds of natural products extracted from plant and animal were used to treat cancer. Flavonoids extracted from tartary buckwheat and skin peptide purified from rufous-spotted torrent frog had respectively been proved to have anti-tumor activity. In present study, both tartary buckwheat flavonoids and amphibian frog peptides were applied for cell proliferation inhibitory activity against human gastric cancer MGC 80-3 cells using MTT assay. According to the data, the buckwheat flavonoids exhibited much stronger anti-tumor activity than amphibian peptides, and the complex mixture of this two kinds of bioactive compounds still possess anti-tumor activity.
