OIL EXTRACT FROM LOCAL LEAVES - AN ALTERNATIVE TO SYNTHETIC MOSQUITO REPELLANTS [PDF]

, 2018
Apart from the fact that chemical based (synthetic) repellents have been discovered to have unfavourable effects on man and livestock, they are expensive, non-biodegradable and no longer efficient due to adaptation of mosquitoes to them.

Larvicidal activity of myricoidine from clerodendrum myricoides

Bulletin of the Chemical Society of Ethiopia, 2004
Chromatographic separation of a methanolic extract of Clerodendrum myricoides led to the isolation of myricoidine (1) whose structure was elucidated using IR, NMR and melting point. The crude fractions as well as 1 were subjected to larvicidal tests using the second instar larvae of Anopheles gambiae (malaria vector) at concentrations of 100, 75, 50 ...

2-HYDROXY-4-METHOXYBENZALDEHYDE: LARVICIDAL STRUCTURE-ACTIVITY STUDIES

Bulletin of the Chemical Society of Ethiopia, 2005
2-Hydroxy-4-methoxybenzaldehyde (1), a compound isolated from Mondia whytei (Hook) Skeels (Asclepiaceae) roots exhibited larvicidal activity (LD5022 mg/mL). A total of 18 other derivatives and closely related congeners revealed varying levels of larvicidal activity.
