Identification of sucrose diesters of aryldihydronaphthalene-type lignans from Trigonotis peduncularis and the nature of their fluorescence.
Phytochemical investigation of Trigonotis peduncularis resulted in the isolation of three aryldihydronaphthalene-type lignan sucrose diesters named trigonotins A-C (1-3). These lignans showed a strong yellow-green fluorescence emission under basic conditions. The structures of the new compounds were elucidated by means of spectroscopic methods, and the nature of their fluorescence was examined.
