BACKGROUND
Nothing is reported on Amphilophium paniculatum (L.) Kunth. This study aimed at investigation of chemical constituents of the leaves of Amphilophium paniculatum, grown in Egypt, in addition to pharmacological evaluation.
METHODS
Isolation of a new compound, along with 5 known flavonoids.
Four new triterpenoids; One oleanane-, one ursane- and two cycloartane-type triterpenoids, named amphipaniculosides A-D, in addition to one new aliphatic alcohol glycoside, named amphipaniculoside E, were isolated from the 1-BuOH fraction of the leaves of Amphilophium paniculatum (L.) Kunth.,
Sixteen crude extracts from six Panamanian plants of the family Bignoniaceae were submitted to rapid TLC tests against DPPH and acetylcholinesterase. Pithecoctenium crucigerum (L.) A.H. Gentry, which showed interesting activity against DPPH, has been studied. The chemical investigation of the
