β-D-Glucopyranosiduronic acid, (3β)-28-(β-D-glucopyranosyloxy)-28-oxoolean-12-en-3-yl O-6-deoxy-α-L-mannopyranosyl-(1→3)-O-[β-D-glucopyranosyl-(1→2)]- Usage And Synthesis

Uses

3-O-β-D-Glucopyranosyl(1→2)-[a-Lrhamnopyranosyl(1→3)]-β-D-glucopyranosyl 28-O-β-D-glucuronopyranoside, a saponin, is isolated from Polaskia chichipe Backbg. 3-O-β-D-Glucopyranosyl(1→2)-[a-Lrhamnopyranosyl(1→3)]-β-D-glucopyranosyl 28-O-β-D-glucuronopyranoside shows ability to inhibit melanin biosynthesis by B16 melanoma cell with inhibitory activity 84.2% at 100μM[1].
