Objective:
To isolate and identify the chemical constituents from the flowers of Ailanthus altissima.
Methods:
Macroporous adsorptive resins (DM130), Silica gel, Sephadex LH-20, ODS were employed for the isolation and purification of chemical constituents. The structures were identified on the basis of spectral data and physicochemical examination.
Results:
Eight compounds were isolated and identified as follows: brevifolin (1), brevifolin carboxylic acid (2), methyl brevifolin carboxylate (3), ellagic acid (4), diethyl-2,2',3,3',4,4'- hexahydroxybiphenyl-6,6'-dicarboxylate (5), rutin (6), gallic acid (7), ethyl gallate (8).
Conclusion:
Compounds 1 -5 are isolated from this genus for the first time.
