[Terpenoids from Euphorbia antiquorum L.].
To study the chemical constituents of Euphorbia antiquorum L., the constituents were isolated with normal-phase and reverse-phase silica gel column chromatography and their structures were elucidated on the basis of spectroscopic data. Seven terpenoids were obtained from EtOAc extract of E. antiquoru L. They were identified as antiquorine A (1), antiquorine B (2), ent-13S-hydroxy-16-atisene-3,1...
متن کاملSupercritical Fluid Extraction of Terpenoids and Steroids from Plants
Terpenoids and steroids constitute the largest known group of plant secondary metabolites. The different groups of terpenes are formed from isoprene (C5) units in enzymatic reactions. Head-to-tail condensation of isoprene units results in the formation of monoterpenes (C10), sesquiterpenes (C15), diterpenes (C20), sesterpenes (C25) and polyterpenes. Tail-to-tail coupling of C15 and C20 units le...
متن کاملTriterpenes 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...

متن کاملSome modern mass spectrometric methods for steroids and terpenoids.
Introduction Mass spectrometry has been applied to isoprenoid molecules for many years, resulting in well established analytical procedures such as combined gas chromatography-mass spectrometry (Rose & Johnstone, 1982; Rose, 1983). Such methods are not discussed here. Obviously, this does not reflect their value: g.c.-m.s. is an excellent tool for detection, identification and quantification of...
