Bioactivity-guided studies on the antiinflammatory activity of extract of aerial parts of Schwenckia americana L. (Solanaceae)

The antiinflammatory activity of the methanol:methylene chloride extract of the aerial parts of Schwenckia americana L. (Solanaceae) (SAE) and its mechanisms were evaluated. Bioactivity-guided studies on SAE and its fractions was done using the egg albumin-induced rat paw edema as activity guide. Further screening for anti-inflammatory activity was accomplished using the xylene-induced ear edema and cotton...

Biotechnical application of arbuscular mycorrhizal fungi used in the production of foliar biomolecules in ironwood seedlings [Libidibia ferrea (Mart. ex Tul.) L.P.Queiroz var. ferrea]

Libidibia ferrea, popularly known as ironwood is a medicinal plant of the Caatinga, in semi-arid Brazil. It is used for traditional medicine because it has bioactive compounds. Arbuscular mycorrhizal fungi (AMF) have been shown to improve the production of biomolecules in some plants. The objective of this study was to select efficient AMF for optimizing the growth and production of bioactive compounds in L. ferrea...
