Abstract

A composition for inhibiting a liver tumor in an organism is disclosed. The composition includes an activator being 1,2,3,4,6-penta-O-galloyl-Beta-D-glucopyranoside (PGG), wherein PGG is extracted from at least one of Paeonia lactiflora Pall. and Galla Chinesis.

Claims (5)

1. A method of manufacturing a pharmaceutical composition for a treatment of a liver cancer, a prostate cancer or a human promyelocytic leukemia, comprising the steps of:

providing an extract including a compound of 1,2,3,4,6-penta-O-galloyl-Beta-D-glucopyranoside (PGG), wherein the extract is extracted from Galla Chinesis via methanol;

separating the compound of PGG by a medium-pressure liquid chromatography (MPLC), wherein an E1 fraction is washed-out by dichloromethane:methanol=90:10, an E2 fraction is washed-out by ethyl acetate:methanol:0.1% acetic acid=15:2:0.5, and an E3 fraction is washed-out by 100% methanol, and the fractions E1-E3 are assayed by silica TLC via using a mixture of ethyl acetate:methanl:0.1% acetic acid=15:2:0.5 as the mobile phase to obtain a first active fraction;

separating and purifying the first active fraction by a Sephadex LH-20 column, via using methanol as the mobile phase to obtain a second active fraction; and

performing a UPLC analysis on the second active fraction.
