Abstract

Starting from commercially available scutellarin, a natural flavonoid glycoside 6-hydroxyapigenin-7-O-(6”-O-(E)-coumaroyl)-β-glucopyranoside was semi-synthesized in a linear 6-step sequence with an overall yield of 31.5%. This work definitely laid the foundation for the further pharmacological study of this natural compound.
