[Alkaloids and flavonoid from aerial parts of Hammada articulata ssp. scoparia]. / Alcaloïdes et flavonoïde des parties aériennes de Hammada articulata ssp. scoparia.

Two alkaloids (N-methylisosalsoline and carnegine) had been previously described from the aerial parts of Hammada articulata ssp. scoparia. A thorough study of this plant material has now led to the isolation of eight minor alkaloids and one flavonoid. The alkaloids include four isoquinolines (isosalsoline, salsolidine, dehydrosalsolidine and isosalsolidine), one isoquinolone (N-methylcorydaldine), tryptamine, N-omega-methyltryptamine and one beta-carboline (tetrahydroharman). The flavonoid has been identified as isorhamnetin-3-O-beta-D-robinobioside. The structures have been elucidated on the basis of spectral data, mainly mass spectrometry (D-IC) and 1H NMR.

[Isolation and properties of Sarothamnoside, a novel isoflavone glycoside from various Sarothamnus species]. / Isolement et Etude du Sarothamnoside, Nouvel Heteroside d'Isoflavone de Divers Sarothamnus.

Sarothamnoside (genistein 7,4'-di-O-[4-O-beta-D-glucopyranosyl-beta-D-apiofuranoside]), a novel isoflavone glycoside, has been isolated from Sarothamnus scoparius and S. patens seeds. The structure, in agreement with acid and enzymatic hydrolysis experiments, has been unambiguously determined, using spectral methods: SM, (1)H NMR and (13)C NMR. (1)H NMR spectra showed the beta configuration of the two apioses, whereas (13)C NMR provided evidence of the sugar linkages.
