Abstract:
OBJECTIVETo study the chemical constitutes of caulis Marsdeniae tenocissimae.
METHOD70% ethanol extracts of caulis M. tenocissimae were isolated and purified by silica gel column chromatography, Sephadex LH-20 chromatography and semi-preparative reversed phase liquid chromatography (RPLC). The compounds were identified on the basis of spectral analysis, including NMR, MS and IR.
RESULTSeven compounds were obtained and identified and their structures were identified as beta-sitosterol (1), condutirol(2), dihydroconduritol(3), betulinic acid(4), lupeol(5), daucosterol(6), 11alpha-O-(2-methylbutyryl)-12beta-O-acetyltenacigeninB(7).
CONCLUSIONCompound 4, 5 were isolated from the genus for the first time.
