Abstract

The dissertation describes the characterization of the chemical constituents of two plants of the genus Euphorbia from the family Euphorbiacear. Euphorbia decipiens Boiss. & Buhse and Euphorbia teheranica Boiss., which are endemic to Iran. And the essential oil of Zataria multiflora Boiss (Lamiaccae) from Pakistan. Investigation of E. decipiens results in five novel diterpenoids with a new parent alcohol skeleton. Named as decipinone (79), isodecipinone (84), decipidone (85), isodecipidone (86) and decipinone A (87), and two noel tetracyclic diterpenoids, decipinol ester A (88) and B(90). Karajinone A(91) and B(94) were identified as two new pentacyclic diterpene esters with a rare carbon skeleton related to lathyrol. The known compounds isolated from this plant included, B-sitosterol (95), cycloeucalenol (96) obtusifoliol (97), cycloart-23-ene-3,25-diol (98), and 24-methylenecycloartan-3B-ol(99).
