Phytochemical investigation of the MeOH extract of the aerial parts of Bistorta manshuriensis resulted in the isolation of two cerebrosides, two lactams, six phenolic compounds and seven flavonoids. Their chemical structures were characterized by spectroscopic methods to be pinelloside (1), soyacerebroside I (2), pterolactam (3), 5-hydroxypyrrolidine-2-one (4), vanillic acid (5), caffeic acid methyl ester (6), protocatechuic acid (7), caffeic acid (8), 3,5-di-O-caffeoyl quinic acid methyl ester (9), chlorogenic acid methyl ester (10), avicularin (11), afzelin (12), quercetin (13), isoorientin (14), quercetin 3-O-${\beta}$-D-glucoside (15), quercitrin (16), and luteolin (17). The isolated compounds (1 - 4, 7, 12, 14) were isolated for the first time from this plant source and the compounds 1 - 4, 9 and 10 were first reported from the genus Bistorta. Compound 17 exhibited moderate cytotoxicity and compound 6 exhibited weak cytotoxicity against four human cancer cell lines in vitro using an SRB bioassay.

This study was purposed to research the anti-cancer effects of Bistortae Rhizoma. A total extract of Bistortae Rhizoma decoction was prepared. By measuring the cell proliferation, apoptosis, morphology and cytokine level from the extracts, the influence on HepG2 cell, SNU-1 cell and A549 cell was compared. The Bistortae Rhizoma decoction extract did not control HepG2 cell proliferation but controlled SNU-1 cell and A549 cell proliferation. In particular, the inhibitory effect on SNU-1 cell proliferation was highest. The Bistortae Rhizoma decoction extract showed to increase the apoptosis of the HepG2 ceil, SNU-1 cell and A549 cell in a dose-dependent manner. In particular, the promotion effect of the apoptosis was highest in SNU-1 cell. Among the various fraction extracts of the Bistortae Rhizoma decoction, n-BuOH extraction showed the greatest increase of the apoptosis of the HepG2 cell. The Bistortae Rhizoma decoction extract decreased dose-dependently the secretion of the TGF-$\beta$ in the HepG2 cell, SNU-1 cell and A549 cell and increased the secretion of the TNF-$\alpha$ and the IFN-$\gamma$. These results suggest that the total extract of Bistortae Rhizoma decoction has anti-cancer effect against SNU-1 cell and A549 cell.
