“…Leaf powders from S. longipedunculata collected from two different geographical areas, Atacora and Borgou in Benin (West Africa), exhibited percentage mortality rates of 18.9 and 77.2 respectively against Callosobruchus maculatus (Boeke et al, 2004 (Belmain et al, 2001). The methanol extract of the leaf showed a 50% mortality rate at 1.0, 2.0 and 3 ppm, while the ethanol extracts of both the stem bark and leaf resulted in a 70% mortality rate against juvenile snails of Balinus globusus (Olofintoye, 2010).…”

Ethnopharmacologicalrelevance: Securidaca longipedunculata Fresen (Polygalaceae) is a multi-purpose plant with a long history of use in African traditional medicine to treat various sexually transmitted infections, hernias, coughs, fever, ascariasis, constipation, headaches, rheumatism, stomach ache, malaria, tuberculosis, pain, epilepsy, pneumonia, skin infections, and it is also used as an aphrodisiac for men. The current paper provides an overview of the present phytochemistry, toxicology, ethnomedicinal uses and pharmacological properties of S. longipedunculata. Materials and methods:The information reported in this paper was collected from a literature search using various computerised databases including ScienceDirect, Moreover, the pharmacokinetic properties of extracts and compounds of the species need to be explored as there is insufficient data available on these aspects.

“…In other similar bioassays, A. indica powders caused more than 50% mortality of several stored-product insect pests of maize including P. truncatus (Sharma 1995;Chiranjeevi & Sudharkar 1996). The observed toxic and reproduction inhibition effects of L. camara, T. vogelii, and A. indica could be a result of documented bioactive chemical principles such as isoflavanoids, flavanoids, terpenoids, and azadarachtins among other compounds (Boeke et al 2004). For example Rahim (1998) reported that azadirachtin, at 5 mg/kg grain, inhibited Rhyzopertha dominica (F.) F 1 progeny production by more than 98% over a 48-week storage period.…”

“…In Cameroon it is used as an insecticide against stored-grain pests. The insecticidal and repellent activities against stored grain pests and feedingdeterrence activity against blowfly larvae have been confirmed in scientific studies (Boeke et al 2004;Ndomo et al 2008;Mukandiwa et al 2013). In Kenya and Ethiopia, the leaves of C.…”

Mosquitoes are rapidly developing resistance to insecticides that millions of people relied on to protect themselves from the diseases they carry, thereby creating a need to develop new insecticides. Clausena anisata is used traditionally as an insect repellent by various communities in Africa and Asia. For this study, the repellency and adulticidal activities of leaf extracts and compounds isolated from this plant species were evaluated against the yellow fever mosquito, Aedes aegypti. In the topical application assays, using total bites as an indicator, repellency was dose-dependent, with the acetone crude extract (15% ) having 93% repellence and the hexane fraction (7.5%) 67% repellence after 3 h. Fractionation resulted in a loss of total repellence. As mosquito-net treating agents, the acetone and hexane extracts of C. anisata, both at 15%, had average repellences of 46.89 ± 2.95 and 50.13 ± 2.02 %, respectively, 3 h after exposure. The C. anisata acetone extract and its hexane fraction caused mosquito knockdown and eventually death when nebulised into the testing chamber, with an EC 50 of 78.9mg/ml (7.89%) and 71.6 mg/ml (7.16%) in the first 15 minutes after spraying.Clausena anisata leaf extracts have potential to be included in protection products against mosquitoes due to the repellent and cidal compounds contained therein.
