From the stem bark of Millettia usaramensis subsp. usaramensis four new 12a-hydroxyrotenoids with the unusual trans B/C ring junction ((+)-12a-epimillettosin, (+)-usararotenoid-A, (+)-12-dihydrousararotenoid-A, and (+)-usararotenoid-B), a new α-hydroxydihydrochalcone (α,4,2′-trihydroxy-4′-O-geranyldihydrochalcone), a new isoflavone, (norisojamicin), and a new cinnamyl alcohol derivative (4-O-geranylcinnamyl acetate) have been isolated and characterized. In addition, the known compounds 4′-O… Expand

Rotenoids, Flavonoids, and Chalcones from the Root Bark of Millettia usaramensis.
TLDR
Five new compounds and a new natural product were isolated from the CH2Cl2/MeOH extract of the root bark of Millettia usaramensis by chromatographic separation and their absolute configurations were established on the basis of chiroptical data and in some cases also by X-ray crystallography. Expand

Flavonoids and Isoflavonoids of Millettia dura and Millettia ferruginea: Phytochemical review and chemotaxonomic values
TLDR
In these taxa, oxygenation at C-6 is a common feature, while isoflavones with C-8 oxygenation are rare, while this appears to distinguish M. dura from M. ferruginea. Expand

The dichloromethane extract of the stem bark of Millettia usaramensis subspecies usaramensis showed anti-plasmodial activity against the chloroquine sensitive (D6) and chloroquine resistant (W2)Expand
PHYTOCHEMISTRY AND BIOLOGICAL ACTIVITY OF THE ROOT EXTRACT OF MILLETTIA OBLATA
TLDR
The genus Millettia belongs to Leguminoseae family, Tephroseae tribe and is known to elaborate prenylated flavonoids and isoflavonoids, which are known to show anti-bacterial and anti-fungal activity. Expand
A single chalcone and additional rotenoids from Lonchocarpus nicou.

Larvicidal Activities Of The Stem Bark Extract And Rotenoids Of Millettia Usaramensis Subspecies Usaramensis On Aedes Aegypti L. (diptera: Culicidae)
TLDR
This compound appears to be the first rotenoid having a trans-B/C ring junction and methylenedioxy group at C-2/C-3 with high larvicidal activity. Expand
Rare Prenylated Isoflavones from Tephrosia calophylla
TLDR
Ariculasin and isoauriculasin are reported for the first time with full NMR assignments and all metabolites were fully characterized by 1D and 2D NMR techniques including COSY, HSQC, HMBC experiments, mass spectra and on the basis of X-ray diffraction. Expand
