THE COMPOSITION OF PHYTOSTEROLS, LATEX TRITERPENOLS AND WAX TRITERPENOIDS IN THE SEEDLING OF EUPHORBIA-LATHYRIS L

In the etiolated seedling of Euphorbia lathyris L., three groups of triterpenoids were found, located at different sites. The extracted triterpenoids were purified by TLC and HPLC and identified by GC/MS. Latex consisted mainly of triterpene alcohols. From these, guimarenol, 24-CH3-lanosterol and hopenol-B were not earlier identified in E. lathyris. The epicuticular wax contained mainly triterpene ketones, which were identified as taraxeron, hopenone-I, hopenone-II, hopenone-B, 3-oxo-22-hydroxyhopane, simiarenone and fernenone. Other components of the epicuticular wax were triterpenols, n-alkanes and aliphatic alcohols. The phytosterols were identified as cholesterol, campesterol, stigmasterol, sitosterol and isofucosterol.
