Article abstract of DOI:10.1016/0031-9422(88)83136-4

Two new triterpenoids were isolated together with β-amyrin acetate, taraxeryl acetate, lupenyl acetate, 3β-acetoxy-30-norlupan-20-one- α-amyrenonol and sitosterol from the whole herb of Euphorbia maculata.The structures of the new compounds were characterized as gult-5-en-3β-yl acetate, and ursa-9(11):12-dien-3β-ol on the basis of chemical and spectral evidence.Key Word Index-Euphorbia maculata; Euphorbiaceae; β-amyrin acetate; taraxeryl acetate; lupenyl acetate; 3β-acetoxy-30-norlupan-20-one; α-amyrenonol; gult-5-en-3β-yl acetate; ursa-9 (11):12-dien-3β-ol; sitosterol.
