Study on Chemical Constituents from Eupatorium adenophorum Spreng

Abstract:

In order to understand the chemical constituents of Eupatorium adenophorum Spreng., seven compounds were isolated from its ethanol extract. On the basis of spectral data, they were identified as patulitrin (1), 7-O-(6-methoxykaempferol)-β-d-glucopranoside (2), 4'-methoxylpatulitrin (3), 3-O-(6-methoxykaempferol)-β-dglucopranoside (4), dibutyl phthalate (5), bis(2-ethylhexyl)phthalat (6), 1,4-bis(2-benzoxazolyl)naphthalene (7). Compounds 1-4 were isolated from this plant for the first time.
