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).
