Anti-insect Activity of Bufadienolides from Urginea maritima

Squill [Urginea maritima (L.) Baker, Liliaceae] is a native medicinal and ornamental plant from the Mediterranean area. The bulbs were an ancient source of rodenticide products replaced later on by warfarin and modern anticoagulant raticides. Since rats have developed resistance to such products there is now renewed interest in the species. In the 1950s, attempts were made in the United States ...

Determination of Antioxidant Activities of Different Urginea maritima (L.) Baker Plant Extracts

The subject handled in this study is the determination of antioxidant activities of extracts obtained from the Urginea maritima (L.) Baker plant’s leaves and tubers. Extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. The antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. Moreover, the free radica...

Bufadienolides and a new lignan from the bulbs of Urginea maritima.

Thirty three compounds were obtained from the bulbs of Urginea maritima (Liliaceae). The compounds were identified by means of fast atom bombardment mass spectrometry (FAB-MS), nuclear magnetic resonance (1H-NMR), (13C-NMR), nuclear overhauser effects (NOE) and two dimensional (2D) NMR. Ten of them were new natural compounds. Nine were bufadienolides and only one was lignan in these compounds.
