Triterpenes from Euphorbia rigida

Triterpenes from Euphorbia spinidens with immunomodulatory activity

Dried aceton-chloroform extract of aerial parts of Euphorbia spinidens Bornm. ex Prokh. endemic to Iran, yielded two new triterpenoids, lup-20(29)-ene-33, 28 diol commonly known as betulin and (3β,23E)-Cycloarta-23-ene-3,25-diol. The structures of the isolated compounds were elucidated by 13C- and 1H-NMR as well as 2D-NMR, IR and by the aid of mass fragmentation pattern. In phagocyte chemilumin...

Triterpenes and steroids from Euphorbia denticulate Lam. with Anti-Herpes Symplex virus activity

In this research, dried acetone:chloroform extract of aerial parts of E. denticulata as one of the endemic plants to Iran, afforded a number of triterpenes and steroids including: betulin, 24-methylene-cycloart-3-ol, cycloart-23Z-ene-3β,25-diol, cycloart-23Z-ene-3β,25-diol, ergosta-8,24-dien-3-ol (obtusifoliol) and beta-sitosterol which were reported for the first time from this plant. The stru...
