[Study on chemical constituents from flowers of Ailanthus altissima].

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.
