Synthesis and chemical shifts of five new rotenoids.

open access: yes, 2012
Five new rotenoids are prepared using the synthetic approach developed by Pastine and Sames with some modifications. The 1H and 13C NMR resonances were assigned completely with certainty using a concerted application of one- and two-dimensional ...

Antiplasmodial and larvicidal flavonoids from Derris trifoliate

open access: yesBulletin of the Chemical Society of Ethiopia, 2009
From the dichloromethane-methanol (1:1) extract of the seed pods of Derris trifoliata, a new flavanone derivative (S)-lupinifolin 4´-methyl ether was isolated. In addition, the known flavonoids lupinifolin and rotenone were identified.

Isoflavones and Rotenoids from the Leaves of Millettia brandisiana

open access: yesChemical and Pharmaceutical Bulletin, 2008
A new isoflavone, 4'-gamma,gamma-dimethylallyloxy-5,7,2',5'-tetramethoxyisoflavone, brandisianin A (1), was isolated from the leaves of Millettia brandisiana, along with one synthetically known isoflavone, 7,4'-di-O-prenylgenistein (2) and twelve known compounds. The structures were elucidated on the basis of extensive spectroscopic analysis.

Highly variable insect control efficacy of Tephrosia vogelii chemotypes

open access: yes, 2012
Tephrosia vogelii has been used for generations as a pest control material in Africa. Recently, two chemotypes have been reported based on the occurrence (chemotype 1) or absence (chemotype 2) of rotenoids.
