The ethanol extract of the aerial parts of Genista tenera (Leguminosae) afforded the pyranoisoflavone alpinumisoflavone (1) the isoflavones genistein (2) 5-O-methylgenistein (3), 3’-O-methylorobol (4) 5-O-methylgenistein 7-O-β-d-glucopyranoside (5) and the flavones apigenin (6) and chrysoeriol (7). LSIMS data of compound 1 is presented and discussed, together with its physical and spectroscopic data, namely NMR and UV.

A phytochemical study of the quinolizidine alkaloids from Genista tenera by gas chromatography-mass spectrometry.
TLDR
Gas chromatography coupled with mass spectrometry has been used to analyse the alkaloids present in the aerial parts of Genista tenera, characterisation of the constituents was based on comparison of their Kovats retention indexes and electron impact-mass spectrometric data recorded on-line with those of reference compounds and literature data.

Antihyperglycaemic and protective effects of flavonoids on streptozotocin–induced diabetic rats
TLDR
Almost all the tested compounds effectively protected the liver and kidneys against STZ‐induced damage in rats, and significantly lowered the blood glucose levels of diabetic animals. Expand

Flavonoids from genista ephedroides
TLDR
Three new flavonoids were isolated from the aerial parts of Genista ephedroides by means of spectroscopic methods and established as hydroxyalpinumisoflavone, ephedroidin and genisteone. Expand

Structural characterisation of flavonoids and flavonoid-O-glycosides extracted from Genista tenera by fast-atom bombardment tandem mass spectrometry.
TLDR
Characteristic fragmentation patterns were observed in all the investigated compounds; the loss of small neutral species from the protonated molecules was useful for identifying the presence of specific functional groups in the A- and B-rings. Expand
Techniques of flavonoid identification.
TLDR
This book presents a more extensive, up-to-date and thorough guide to techniques used in flavonoid research, and discusses examples of a wide range of spectra, and features diagrams of flavonoids structures, reaction schemes and apparatus. Expand
