Optical resolution of rotenoids
Journal of Heterocyclic Chemistry, 1987 AbstractOptical resolution of selected rotenoids containing 1‐3 asymmetric centers in dihydrobenzopyranofuroben‐zopyranone and dihydrobisbenzopyranopyranone series has been achieved on two chiral high‐performance liquid chromatographic (hplc) stationary phases.

Antiinflammatory activity of rotenoids from Clitoria fairchildiana
Phytotherapy Research, 2002Five structurally related rotenoids were isolated from the roots of Clitoria fairchildiana. The antiinflammatory activity was investigated using a capillary permeability assay. The protective effect was measured as the inhibition in vascular permeability produced by acetic acid in the peritoneal cavity. The results suggest that for maximum activity the

Effect of rotenoids from the seeds ofMillettia dura on larvae ofAedes aegypti
Pest Management Science, 2003 A crude chloroform extract of seeds of Millettia dura Dunn (Leguminosae) showed high activity (LC50 = 3.5 µg ml−1 at 24 h) against second-instar larvae of the mosquito, Aedes aegypti L (Diptera: Culicidae). The rotenoids, deguelin and tephrosin, isolated

NMR investigations of rotenoids
Tetrahedron, 1973Abstract Extensive NMR studies of major rotenoids have (1) verified the cis B/C ring fusion of rotenone; (2) confirmed the structure of the reduction-dehydration product of rotenone; (3) provided considerable evidence regarding the preferred conformations of rotenoids; (4) revealed an array of long-range couplings; and (5) pointed up analytically ...
