“…The triterpenes (C30) include steroids, sterols, and cardiac glycosides with anti-inflammatory, sedative, insecticidal or cytotoxic activity. Common triterpenes: amyrins, ursolic acid and oleanic acid sesquiterpene (C15) like monoterpenes, are major components of many essential oils (Martinez et al, 2008). The sesquiterpene acts as irritants when applied externally and when consumed internally their action resembles that of gastrointestinal tract irritant.…”

“…Essential oils have a tendency evaporate on exposure to air even at ambient conditions and are therefore also referred to as volatile oils or ethereal oils. They mostly contribute to the odoriferous constituents or 'essences' of the aromatic plants that are used abundantly in enhancing the aroma of some spices (Martinez et al, 2008 (Firn, 2010).…”

“…Terpenes are flammable unsaturated hydrocarbons, existing in liquid form commonly found in essential oils. Monoterpenes, are of aromatic plants that are used in repelling insect when they are burnt [22,41,42]. However, in rural homes there is the need to reduce cost of using energy to extract the leaves, the risk of fire outbreak in the use of smoke, and nuisance resulting from topical application of repellents.…”

Article HistoryIn this study the ethnobotanical use of mosquito repelling plant leaves as a preventive measure against mosquitoes thus malaria was investigated. Phytochemical screening of ethanol and aqueous extracts, and mosquito repellency tests of powdered dried leaves of Hyptis suaveolens, Cassia obtusifolia and Striga hermonthica in an olfactometer were carried out and compared with two standard repellants. In leaves of Striga hermonthica, glycosides, flavonoids, tannins, ketones, alkaloids, reducing sugar and phlobotannins, steroids and terpenoids were present. Hyptis suaveolens leaves had glycosides, tannins, alkaloids, reducing sugar, phlobotannins, ketones and coumarins, flavonoids, terpenoids and steroids. In Cassia obtusifolia leaves, flavonoids, anthraquinone, ketones, coumarins, terpenoids and phlobotannins, glycosides, saponins, tannins, steroids, alkaloids and reducing sugar were also present. S. hermonthica was the most repellent among the three plant leaves, and repelled 11.50±0.50, 6.50±0.63 and 8.33± 0.82 mean number of mosquitoes when it was compared to empty chamber, Hyptis suaveolens leaves and Cassia obtusifolia leaves respectively. Leaves of H. suaveolens were the second efficient repellant sample. It repelled 10.17±0.52 and 8.00±0.79 mean number of mosquitoes when it was compared with empty chamber and C. obtusifolia leaves respectively. Cassia obtusifolia leaves were the least repellent and mean numbers of mosquitoes repelled were 6.58±0.42 and 5.42±0.54 respectively compared to empty chamber and Hyptis suaveolens. The repellence efficiency of Striga hermonthica, Hyptis suaveolens and Cassia obtusifolia were 83.4, 78.3 and 70.4 % respectively compared with the standard, 90.0 %. Striga hermonthica compared well with the standard repellent and could be used to repel mosquitoes to avoid their bites. Contribution/ Originality:This work contributes to new ways of reducing mosquito bites, hence incidence of malaria. A new approach, the olfactometer, was used to investigate the mosquito vector. A direct comparison of naturally growing mosquito repellents, Striga hermonthica and Hyptis suaveolens, was established, for possible use to formulate herbal mosquito repellents.

Abstract:In an attempt to investigate the phyto-constituents present in the root bark and root core of Cassia ferruginea (Schrad D.C) plant due to acclaimed medicinal wide range uses of the plant especially for mental illness, sexual dysfunction and microbial infections, both the root bark and root core of Cassia ferruginea (Schrad D.C) plant were collected, processed and extracted using 95% ethanol. Phytochemical analysis method was used to determine the various constituents present qualitatively. The study revealed the presence of Alkaloids, Tannin, Saponins, Phenols, Flavonoid, and Cardiac glycosides in both root bark and the root core sample, in addition to Protein, Quinone, and Coumarins in the root bark except for steroid which was only present in the root core of Cassia ferruginea (Schrad D.C) plant. The study has shown the nature distribution of phyto-constituents in plant at different parts, no matter how close the parts are. As, such all the parts of plant are necessary to be considered useful as its contained different components.
