Free triterpenols and sterols produced by in vitro cultures and laticifer cells from Euphorbia characias 

 -  PhytoChemistry, 29(6), p.1855-1860, 1990 .
<br/><br/> The trlterpenol constituents of Euphorbia charac~~s subsp. charmus latex and of tn vrtro cultured calli and cells were examined by capillary GLC and mass spectrometry. The capillary GLC tnterpenol profile of the petrol extracts obtained from in vitro cultures is completely different from that of the latex, The major triterpenols produced by zn vitro cultures are campesterol, sltosterol, A5-avenasterol and a-amyrin, as they were identified by mass spectra of their trimethylslhlated and acetylated derivatives, while laticlfer cells produce lanosterol, a lanosterol isomer, cycloartenol, 24-methylenecycloartanol and another sterol Identified as a cycloartenol isomer.
