Abstract
From the dichloromethane extract of Ulex airensis three new isoflavonoids, ulexin C (1), ulexin D (2), and 7-O-methylisolupalbigenin (3), were isolated and characterized by spectroscopic methods. Ulexin D (2) was also identified from the dichloromethane extract of Ulex europaeus ssp. europaeus. Together with these new metabolites, 18 compounds of previously known structures were isolated and identified from both species. The antifungal activity of these compounds was tested against Cladosporium cucumerinum by a bioautographic TLC assay.

Abstract
The analysis of polyphenols, which are characteristic of certain legumes, enables a rapid and sensitive detection of legume proteins in meat products. Separation of specific isoflavones can be achieved by capillary zone electrophoresis (CZE) or high-performance liquid chromatography (HPLC), both coupled with a photodiode array detector (DAD). The use of CZE in the identification process is an appropriate means of rapid screening; the HPLC is less dependent on matrix effects and clearly more sensitive. Additives of soy protein isolates up to 0.1% could be detected in meat products, even in sausages heated to a high temperature or with hydrolyzed soy proteins. A solid-phase extraction procedure with polyamide cartridges has been developed to concentrate polyphenols. A similar detection of lupin protein is possible in principle. In the case of pea protein, a reliable detection was not possible depending on the coincidental appearance of polyphenols as indicating substances.
