A New Diamine of Mahonia fortunei
摘要
A new diamine, mahodiamine (1), along with 11 compounds, including scopoletin (2), isoscopoletin (3), aesculetin dimethyl ester (4), p-methoxylbenzoic acid (5), protocatechuic acid (6), ferulic acid (7), (+)-vomifoliol (8), (+)-dehydrovomifoliol (9), (Z)-4-hydroxy-3,5,5-trimethyl-4-(3′-oxobut-1′-enyl)cyclohex-2-enone (10), bis(2-ethylhexyl) terephthalate (11), and dibutyl phthalate (12), were isolated from the leaves of Mahonia fortunei (Lindl.) Fedde (Berberidaceae). The structure of the new diamine was elucidated by chemical and physical evidence.
