Abstract:
Objective To isolate and identify anti-tumor constituents from Lysimachia christinae Hance.Methods The compounds were isolated and purified by chromategraphy on AB-8 macroporous resin, silica gel, Sephadex LH-20, ODS and preparative HPLC.Their structures were elucidated using chemical and spectroscopic methods.All thecompounds obtained were evaluated on their growth inhibitory effects in vitro using the MTT method.Results Eleven compounds were isolated from the whole plant of L.christinae Hance and were identified as 3,3'-dimethoxy-6,6'-di[(Z)-pentadec-10-en-1-yl]-[1,1'-bi(cyclohexane)]-3,3',6,6'-tetraene-2,2',5,5'-tetraone(1),physcion(2),munjistin(3), 9,16-dioxooctadec-10,12,14-trienoic acid(4),cyclamiretinA-3-O-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabinopyranoside(5),lysikoianoside(6),quercetin-3-O-glucopyranoside(7),isorhamnetin3-O-β-D-galactopyranoside(8),3',4',5',5,7-pentahydroxyflavone(9), rutin(10), and quercetin(11).The screening results of antitumor activity in vitro showed that IC50 of compound 5 for human cervical carcinoma cells HeLa, human osteosarcoma cells U20S, human lung adenocarcinoma cells PC-9,and human colorectal carcinoma cells CT-26 was 2.29, 1.22, 1.43, and 1.29 μmol/L respectively.Conclusion Compound 1 is a new compound and compounds 2-4 are isolated from the plants of Lysimachia for the first time.Compound 5 shows obvious inhibitory effects on tumor cell growth in vitro.
