Derris elliptica roots were collected in the state of Johor; Kota Johor Lama, Malaysia.
For that reason, an internal standard method was carried out to determine the concentration of rotenone in the liquid crude extract of Derris elliptica and to compare the bio-active constituent profile with the commercially available rotenoids cube resin manufactured by SAPHYR (France).
'Tuba' plant is known by its botanical name as Derris elliptica. This commercially important botanical plant like Derris elliptica and Derris malaccensis contains around 4% (w/w) to 5% (w/w) rotenone .
The roots of Derris elliptica plants were dried at room temperature and ground in a knife mill.
'Tuba' is known by its botanical name as Derris elliptica. Rotenone is one of the important bio-active compounds extracted from Derris elliptica and other important constituents of Derris root (e.g., deguelin and tephrosin) have been shown to be toxic to insects as well.
Derris elliptica was collected in the state of Johor; Kulai and Kangkar Pulai, Malaysia.
