Strychnos icaja Baill. (Loganiaceae) is a liana found in Central Africa known to be an arrow and ordeal poison but also used by traditional medicine to treat malaria. Recently, many dimeric or trimeric indolomonoterpenic alkaloids with antiplasmodial properties have been isolated from its rootbark. Since these alkaloids are derivatives of strychnine, it was important, in view of their potential...
A review of plant-based coagulant sources, processes, effectiveness and relevant coagulating mechanisms for treatment of water and wastewater is presented. These coagulants are, in general, used as point-of-use technology in less-developed communities since they are relatively cost-effective compared to chemical coagulants, can be easily processed in usable form and biodegradable. These natural...
BACKGROUND The study was aimed at determining the anti-inflammatory activity of fractions and extracts obtained from Strychnos spinosa leaves on a mediator of inflammation nitric oxide (NO). MATERIALS AND METHODS Leaves were extracted with acetone and separated into fractions with different polarities by solvent-solvent fractionation. The Griess assay was used to determine the nitric oxide (N...
Purpose: To provide an online and non-contact method to monitor the dynamic temperature of the nuxvomica parching in sands, and also to develop a rapid screening and comparison of the compounds in crude and processed nux-vomica. Methods: Seeds of nux-vomica were parched in sands by an herbal medicine roaster with an onlinetype and non-contact temperature measurement system (ONTMS). Processing w...
Usually a moderately-sized liane, Slrychnos giiianemis (Aubl.) Martius occurs in forests, more especially along creeks and small rivers throughout thé middle and upper Rio Orinoco basin and entire Amazon basin (1). Among thé plants of thé Strychnos genus, this Slrychnos is known to be one of thé principal ingrédients of thé curare produced by numerous Indian tribes. This species contains a grou...
Over the last decades agroforestry parklands in Burkina Faso have come under increasing demographic as well as climatic pressures, which are threatening indigenous tree species that contribute substantially to income generation and nutrition in rural households. Analyzing the threats as well as the species vulnerability to them is fundamental for priority setting in conservation planning. Guide...
The larvicidal activity of hexane, chloroform and ethyl acetate leaf extracts of Strychnos nuxvomica against the third instar larvae of Culex quinquefasciatus was studied. The ethyl acetate leaf extract was found to be the effective larvicide with LC value of 222.28 and 146.99 ppm after 24 and 48 hours. The results indicate 50 promising larvicidal activity against Culex quinquefasciatus. Furthe...
