Development and Validation of an HPLC Method for Analysis of Picrasma crenata

Journal of Liquid Chromatography & Related Technologies, 2008
Abstract Picrasma crenata is a Brazilian tree, which is utilized to treat Diabetes mellitus, gastric perturbation, and hypertension. Quassinoids are the main constituents obtained from the wood of this plant. The relationship between the quassinoids and the biological effects reveal the interest of quantifying these constituents in P.

Araucaria angustifolia and Picrasma crenata extracts as potential agents for the control of phytopathogenic fungi of agricultural interest

Caderno Pedagógico
To expand knowledge about native species in southern Brazil, different types of extracts from the thin vinaceous bark of A. angustifolia and fragments of branches of P. crenata were evaluated. These were crushed and kept for fifteen days in contact with hydroalcoholic solutions at 70 % v/v and ethanolic (96 % v/v), seven days in the cold aqueous ...
