Loganiaceae
Preliminary assays indicate that Antonia ovata (Loganiaceae) and Derris amazonica (Papilionaceae), ichthyotoxic plants used for fishing in Roraima, Brazil, have an insecticide effect on Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae). (1/3)
Laboratory-reared Lutzomyia longipalpis (Lutz and Neiva 1912) was tested with extracts of two ichthyotoxic plants, known as timbos, used as fishing poison in the Amazon. Phlebotomines, L. longipalpis, and plants, Antonia ovata and Derris amazonica, were collected in the Raposa-Serra do Sol Indian Reserve, a focus of visceral leishmaniasis in the State of Roraima, Brazil. Extracts were prepared from dried leaves of A. ovata and roots of D. amazonica that were percolated in water, filtered and dried out at 50 degrees C. The solid extract obtained was diluted in water at 150, 200 and 250 mg/ml. The solution was blotted in filter paper placed at the bottom of cylindric glass tubes containing sand flies. For each plant extract and dilution, two series of triplicates with 5 male and 5 female specimens of L. longipalpis were used. Mortality was recorded every 2 h during 72 h of exposure. At 72 h the mortality was as high as 80% for extracts of A. ovata (LD50 = 233 mg/ ml), and 100% for D. amazonica (LD50 = 212 mg/ ml) whereas in the control groups maximum mortality never surpassed 13%. Preliminary assays indicated that A. ovata and D. amazonica displayed significant insecticide effect against L. longipalpis.

Spigelia anthelmia Linn is used as a herb and is a common annual weed of cultivation in open re-growths, on unused land in towns as well as on road sides. The plant can grow to approximately 30 cm in height. The aim of this study was to screen extracts of Spigelia anthelmia for their anthelmintic activity against an experimental Nippostrongylus braziliensis infection in rats. Acute oral toxicity occurred at a dose of 1,140 mg/kg, while anthelmintic trials against Nippostrongylus braziliensis in rats using the aqueous fraction showed a progressive decrease in worm count with increasing dose (10, 13, 16, 20 and 25 mg per kg body weight) (p < 0.05). At 25 mg per kg body weight, the worm count was significantly lower than that at 10 mg per kg body weight (p < 0.05). (+info)Macrocyclic spermidine alkaloids from Androya decaryi L. Perrier. (3/3)
(+info)Loganiaceae is a family of flowering plants in the order Gentianales. It includes trees, shrubs, and herbs, with simple, opposite leaves and showy, often bilaterally symmetrical flowers. The fruits are typically drupes or capsules. Some members of this family contain toxic alkaloids and have been used in traditional medicine. However, it is important to note that the use of these plants for medicinal purposes should only be done under the guidance of a qualified healthcare professional due to their potential toxicity.
"Strychnos" is a genus of plants, specifically belonging to the Loganiaceae family. While not a medical term itself, certain species of Strychnos contain toxic alkaloids that have been used in medicine and are important to understand from a medical and pharmacological perspective.
The most well-known species is Strychnos nux-vomica, which produces the potent alkaloid strychnine. This alkaloid acts as a competitive antagonist at glycine receptors in the central nervous system, leading to uncontrolled muscle contractions, stiffness, and potentially life-threatening convulsions if ingested or otherwise introduced into the body.
Another important alkaloid found in some Strychnos species is brucine, which also has toxic properties, although it is less potent than strychnine. Both of these alkaloids are used in research and have been employed in the past as rodenticides, but their use in medicine is limited due to their high toxicity.
In a medical context, knowing about Strychnos plants and their toxic alkaloids is essential for understanding potential poisonings, recognizing symptoms, and providing appropriate treatment.
