| Abstract: | Ten constituents have been isolated from the ethanolie extract of the stems and leaves of Aristolochia mollissima Hanee. Based on speetrai analysis and the determination of physieo-ehemieal constants they have been identified as: (A1) aristoloehie acid A, (A2) vanillie acid, (A3) aristoloehie acid D, (B1) pahnitone, (B2) n-triacontanol, (B3) β-sitosterol, (B1) aristololaetam, (B11)6-methoxy aristololaetam, (B7) β- sitosterol D-glueoside, (B8) stearic acid. A1 and B1 have been found to have an inhibition action of implantation in mice. |
