Trypanocidal tetrahydrofuran lignans from Peperomia blanda
(Pergamon-Elsevier B.V. Ltd, 2008-01-01)
Five tetrahydrofuran lignans and two known flavones were isolated from the aerial parts of Peperomia blanda. The structures of the isolated lignans were elucidated by interpretation of their spectroscopic data, including ...

Medicinal Attributes of Lignans Extracted from Piper Cubeba: Current Developments
(Wiley-Blackwell, 2018-02-01)
Lignans are a large class of natural products that have been isolated from many plants. They reveal diverse biological activities, especially antiviral and antitumor properties. From Piper cubeba, lignans of several classes ...
Aryltetralols from Holostylis reniformis and syntheses of lignan analogous
(2015-06-27)
Abstract Two new lignans, an aryltetralol and its methyl ether analogous, were isolated from Holostylis reniformis (Aristolochiaceae) together with futokadsurin C and (-)-8′-epi-aristoligone. The latter was also obtained ...
