 Abstract    Euphorbiaceae, 8. Mitt. [1] Triterpenester und Triterpenalkohole aus Euphorbia biglandulosa Desf. Constituents of Euphorbiaceae, 8. Comm. [1] Triterpen Esters and Triterpen Alcohols from Euphorbia biglandulosa Desf. Fatty acids and acetic acid esters of lanosterol and cycloartenol and triterpens alcohols were isolated from the latex of Euphorbia biglandulosa Desf. The triterpenesters were identified as (E,Z)-2,4-decadienoyllanosterol (la), (E,Z)-2,4-octadienoyllanosterol (lb), (E,Z)-2,4-oc-tadienoylcycloartenol (2a), (2E,4Z)-2,4,6-decatrienoyllanosterol (lc), (2E,4Z)-2,4,6-deca-trienoylcycloartenol (2b), lanosterylacetat (Id) and cycloartenylacetat (2c) by IR-, 'H-NMR-and MS-spectroscopy and hydrolysis. The triterpens alcohols were identified as butyrospermol, cyclo-artenol, 24-methylencycloartanol and obtusifoliol.

 Title    Constituents of Euphorbiaceae, 10. Conun. [1] New Cerebrosides from Euphorbia characias L  
 Abstract    G . P ellizer and F. A sa r o D epartm ent o f Chemical Sciences, U niversity o f Trieste, V ia L. Giorgieri 1 Four new cerebrosides C -l-C -4 were isolated from the latex o f Euphorbia characias L. On the basis o f spectral evidences and chem ical reactions they were characterized as (2 S , 3 S , 4 R , 5 R , 6Z)-l-0-(/?-D -glu cop yran osyl)-2N -[(2'R)-2'-h yd roxy-(15'Z)-tetracose-noyl]-6(Z)-octadecene-l,3,4,5-tetraol-2-am ino (C -l), (2 S , 3 S , 4 R , 5 R, 6 Z)-l-0 -(/? -D -g lu co -p y ra n o sy l)-2 N -[(2 'R)-2 'h y d ro x y -(1 7 'Z)-h ex a c o sen o y l]-6 (Z)-o c ta d e c en e-l,3 ,4 ,5 -te tr a o l-2-am ino(C -2),(2S, 3S , 4 R , 5 R, 6Z)-l-0-(/3-D -glucopyranosyl)-2N -[(2'R)-2'-hydroxy-(19'Z)-octacosenoyl]-6-(Z)-octadecene-l,3,4,5-tetraol-2-am ino (C -3) and (2S , 3 S, 4 R , 5 R, 6 Z)-l-0 -(/?-D -glu cop yran o sy l)-2 N -[(2 'R)-2 '-h y d ro x y -o cta co sa n o y l]-6 -(Z)-o cta d ecen e-l, 3,4,5-tetraol-2-amino (C-4). Reversed phase colum n flash chromatography was effective for the isolation of the cere­ brosides. FA B -M S spectrometry, X H N M R , 13C N M R analysis and chemical reactions were useful in providing information for the structure elucidation.

 Title    Hydrocarbon Distribution in Epicuticular Waxes of Five Euphorbia Species  
 Abstract    The distribution pattern of hydrocarbons in the surface waxes of five species of Euphor­ biaceae, E.caducifolia, E.helioscopia, E.milii, E.royleana and E.tirucalli was studied. In addi­ tion to hom ologous series of n-alkanes, minor quantities of unsaturated and branched hy­ drocarbons were also detected. Some of the branched chain hydrocarbons could be explained as having originated from isoprene units and the substituents corresponding to diterpenes and triterpenes.

 Title    Zur Chemie des Ingenols, I Ingenol und einige seiner Derivate On the Chemistry of Ingenol, I Ingenol and Some of its Derivatives  
 Abstract    The tetracyclic polyfunctional diterpene ingenol (1) is the prototype of many di-terpenoid parent alcohols of the ingenane type. Esters of these parent alcohols occur -partly together with esters of polyfunctional diterpene parent alcohols of the tigliane and daphnane type -as irritant, cocarcinogenic and antineoplastic principles in species of the family Euphorbiaceae (Spurge). Preparation of 1 from latex of Euphorbia ingens E.May as well as of some functional derivatives of 1 are described.
