ABSTRACT
Objective:
To study the chemical constituents of the Eupatorium adenophorum.Methods:
The chemical constituents were isolated and purified by silica gel chromatography repeatedly from the ethyl acetate extract of E. adenophorum, and their structures were identified by spectral analysis and chemical methods.Results:
Fourteen compounds were isolated from E. adenophorum and identified as p-hydroxybenzoic acid ethyl ester (1), (1R,4R)-8aα-hydroxy-1-isopropyl-4,7-dimethyl- 1,2,3,4,6,8a-hexahydro-naphthalene-2,6-dione (2), daedalin A (3), 10-oxo-7-hydroxy-nordehydrotremetone (4), caffeoyl acetate (5), syringic acid (6), 3-hydroxy-4-(1-oxo-ethane)-benzoic acid (7), ferulic acid (8), p-hydroxyphenylethyl alcohol (9), protocatechuic acid ethyl ester (10), 4-hydroxy-3-isopropyl benzoic acid (11), balanophonin (12), indole-3-carboxylic acid (13), and 6-methoxy kaempferol (14).Conclusion:
Compound 11 is obtained from natural products for the first time, compounds 1, 3, 6, 7, 9, 10, 12-14 are obtained from this genus for the first time, and compound 5 is obtained from this plant for the first time.
