Four new sesquiterpenes (1-4), one new alkaloid (5), and one new benzenoid glycoside (6) were characterized from Lindera aggregata, and their structures were elucidated according to their spectrometric analytical data. Among these isolates, 3 and 4 were constructed as possessing unprecedented carbon
OBJECTIVE
To study the alkaloid constituents of the root of Lindera angustifolia Cheng.
METHODS
The constituents were isolated and purified by column chromatography and the structures were characterized by spectral analysis.
RESULTS
Seven aporphine alkaloids, laurotetanine (I), N-methyllaurotetanine
