RESUMEN

To investigate the chemical constituents of seeds of Koelreuteria paniculata Laxm. , components were separated by means of solvent extraction and chromatography on C18, the structure of compound was determined by spectral analysis and chemical evidences. One saponin was obtained and identified as 28-O-isopentyryl-3beta, 16alpha, 22beta, 28-tetrahydroxyl-oleanane-3-O-[ alpha-L-rhamnopyranosyl- ( 1-->3) -betaD-galactopyranosyl-( 1--->4' )]-3betaD-galacturonopyranoside, named paniculata saponin C. This saponin is a new compound.

RESUMEN

<p><b>OBJECTIVE</b>To study the anti-tumor effect and acute toxicity in vitro of the separation compositions from qinglongyi.</p><p><b>METHOD</b>The conventional acute toxicity experiments of mice, the MTT [3-(4,5-dimethylthiazol-2 yl)-2,5-diphenylterazolium bromide, MTT] and the SRB (sulforhodamin B) were used to make preliminary selection to qinglongyi and its separation compositions.</p><p><b>RESULT</b>The half-deadly dose (LD50, the half-lethiferous dose) of the chloroform separation composition in qinglongyi was 575.38 mg x kg(-1) (i.g.), and of the acetic ether separation compositions in qinglongyi was 1303.59 mg x kg(-1) (i.g.). From the other parts of separation compositions in qinglongyi, the LD50 were more than 5 g x kg(-1). When acetic ether separation composition of qinglongyi was at 100 microg x mL(-1) the growth inhibitory rate (GIR) was < 50% to the leukaemia cell HL-60 of human. When chloroform separation composition and the acetic ether separation compositions of qinglongyi was at 100 mg x mL(-1), GIR was 52% to the leukaemia cell HL-60, the gastric carcinoma cell BGC-823 and the cervical carcinoma cell Hela of human.</p><p><b>CONCLUSION</b>The separation composition of the chloroform and the acetic ether from qinglongyi have obvious, anti-tumor effect.</p>
