从大戟全草中分离出两种新的三萜类化合物，以及β-香树醇乙酸酯、蒲公英酯乙酸酯、乙酸羽扇豆酯、3.β.-乙酰氧基-30-正羽扇豆-20-酮、α-杏树醇和谷甾醇。根据化学和光谱证据，新化合物的结构被表征为gult-5-en-3.beta.-ylacetate和ursa-9(11):12-dien-3.beta.-ol。
Two new triterpenoids were isolated together with .beta.-amyrin acetate, taraxeryl acetate, lupenyl acetate, 3.beta.-acetoxy-30-norlupan-20-one, .alpha.-amyrenonol and sitosterol from the whole herb of Euphorbia maculata. The structures of the new compounds were characterized as gult-5-en-3.beta.-yl acetate and ursa-9(11):12-dien-3.beta.-ol on the basis of chemical and spectral evidence.
