1. Tephrosia sinapou extract reduces inflammatory leukocyte recruitment in mice: effect on oxidative stress, nitric oxide and cytokine production
Tephrosia toxicaria (Sw.) Pers., which is currently known as T. sinapou (Buc'hoz) A. Chev., Fabaceae, is a source of compounds such as flavonoids, however, few studies addressed the anti-inflammatory and antioxidant effects of T. sinapou. Therefore, we evaluated the antioxidant mechanisms of the T. sinapou ethyl acetate extract in vitro, and whether the extr

2. Rotenoids from Tephrosia toxicaria with larvicidal activity against Aedes aegypti, the main vector of dengue fever
In the search for new larvicides from plants, we have investigated the potential activity of the rotenoids deguelin (1), 12a-hydroxy-α-toxicarol (2) and tephrosin (3), isolated from the bioactive ethanol extract of roots of Tephrosia toxicaria Pers., against Aedes aegypti, the main vector of dengue. The absolute configuration of these compounds was determin

4. Estudo químico e biológico de Tephrosia toxicaria Pers.
The ethanol extracts from leaves, stems, pods and roots were assayed against the 3rd instar Aedes aegypti larvae and the highest activity was observed in the roots extracts (LC50 47.86 ppm). This extract was submitted to partition with hexane, chloroform, ethyl acetate and methanol. The respective fractions were bioassayed and the best larvicidal activities
