The isolation of salannin from Melia dubia

Structure-bioactivity relationships of salannin as an antifeedant against the Colorado potato beetle (Leptinotarsa decemlineata)

“…The NMR spectrum of li was in agreement with those reported by Henderson et al (1964Henderson et al ( ,1968) and de Silva et al (1969).…”

“…92-1.96,6.96), acetyl ( 1.94), and carbomethoxyl ( 3.24) groups had vanished. EI-MS showed a parent ion at m/z 458, as reported by de Silva et al (1969).…”

“…Salannic Acid (lc). lc was prepared by a modification of the method of de Silva et al (1969). la (30 mg, 0.050 mmol) was dissolved in 2.0 mL of 0.5 M sodium hydroxide in 50% aqueous methanol and the resultant mixture incubated at 70 °C for 3 h. The reaction mixture was poured into 10 mL of 0.5 N hydrochloric acid and extracted three times with 10-mL portions of dichloromethane.…”

Melia dubia Cav. Meliaceae

“…Phytochemical studies on Melia dubia report new tetranortriterpenoids: compositin (1,7-ditiglyl vilasinin), compositolide (photosalannin) followed by salannin from the leaves and seeds (de Silva et al 1969;Puroshothaman et al 1984). Glycosyl derivative of ellagic acid is isolated from the root (Srivastava and Srivastava 1996).…”

LIMONOIDS FROM FRUITS OF Melia dubia Cav. IN VIETNAM

“…The tree enjoys a broad geographical distribution (e.g., in Viet Nam, Indonesia and Philippines) and is well known for its traditional medicinal properties and other biological activities such as insect or larval growth inhibition and as an antifeedant [8]. M. dubia has been shown to be a source of interesting tetranortriterpenoids [9,10]. However, to our knowledge, there are no documents on phytochemical research of fruits of M. dubia in Viet Nam.…”
