High impact information on Derris

  • Fractionation of the aqueous extract of Derris scandens stems extract using tests for eicosanoid inhibition resulted in the isolation of three isoflavonoids, genistein, its 7- O-alpha-rhamno(1-->6)-beta-glucosyl glycoside, a new compound, and two known isoprenyl derivatives 3'-gamma,gamma-dimethylallylweighteone and scandenin [1].
  • From the acetone extract of the roots of Derris trifoliata an isoflavonoid derivative, named 7a-O-methyldeguelol, a modified rotenoid with an open ring-C, representing a new sub-class of isoflavonoids (the sub-class is here named as rotenoloid), was isolated and characterised [2].
  • A benzil and isoflavone derivatives from Derris scandens Benth [3].
  • Isoflavone glycosides from Derris scandens [4].
  • Five isoflavone glycosides, named derriscandenosides A-E (1-5), were isolated from the stems of Derris scandens, together with ten known compounds comprising one isoflavone, two benzoic acid derivatives, three glucosyl isoflavones and four rhamnosyl-(1-->6)-glucosyl isoflavones [4].
 

Anatomical context of Derris

 

Associations of Derris with chemical compounds

  • Rhamnetin-3-O-neohesperidoside, a new flavonoid from the leaves of Derris trifoliata [6].
  • A new triterpenoid: taraxerol-3-beta-O-tridecyl ether from Derris triofoliata [7].
  • Extracts from Rhinacanthus nasutus, Derris elliptica, Trigonostemon reidioides, Homalomena aromatica, Stemona tuberosa and Acorus calamus possessed high larvicidal activity, with LC50 values between 16.0 and 48.2 mg/l. Petroleum ether (PE) and methanol (MeOH) extracts were tested for their larvicidal activity against 4 mosquito vector species [8].
