The Tanino Synthesis of (-)-Glycinoeclepin A
2013(-)-Glycinoeclepin A 3 is effective at pg/mL concentrations as a hatch-stimulating agent for the soybean cyst nematode. Approaching the synthesis of 3, Keiji Tanino of Hokkaido University envisioned (Chemistry Lett. 2010, 39, 835) the convergent coupling of the allylic tosylate 2 with the bridgehead anion 1.

Taninos condensados de Ephedra frustillata Miers (Ephedraceae)
2006The aim of this paper was to study the presence of condensed tannins (proanthocyanidins) from Ephedra frustillata Miers. Methanolic extracts obtained from young and woody stems belonging to male and female plants were analyzed and compared. For both (male and female individuals) the only proanthocyanidin detected in the young stems was prodelphinidin ...

Taninos condensados de Ephedra ochreata Miers (Ephedraceae)
2003El presente trabajo aborda el estudio de los taninos condensados (proantocianidinas) de Ephedra ochreata Miers. Se estudiaron comparativamente extractos metanólicos de tallos herbáceos y leñosos. En ambos materiales se determinó la presencia de prodelfinidina, pero se observó una marcada diferencia cuantitativa entre ellos, caracterizada por altos ...
