摘要
从月腺大戟(Euphorbia ebracteolata Hayata)根中分离出一种新的二苯甲烷化合物——双去甲基伪绵马素-AA和2,4-二羟基-6-甲氧基-3-甲基苯乙酮,并用光谱和化学方法确定前者的结构为3,3′-二乙酰基-4,4′-二甲氧基-2,2′,6,6′-四羟基二苯甲烷。
Didemethylpseudoaspidin AA, a new diphenylmethane, was isolated from the roots of Euphorbia ebracteolata Hayata and assigned its structure: 3,3' -diacetyl- 4,4' -dimethoxy- 2,2', 6,6'-tetrahydroxydiphenylmethane, based on spectroscopic and chemical evidence.
