Phytochemical investigation of the ethyl acetate and n-butanol soluble parts of the aqueous-MeOH extract of the
aerial parts of Genista aspalathoides Lamk ssp. aspalathoides M. collected from El Kala in the eastern Algeria led
to the isolation of isoprunetin, genistein 8-C-b-glucopyranoside and orobol 8-C-b-glucopyranoside. The structures
were established by spectral analysis, mainly ESIMS, UV and 2D-NMR experiments (COSY, HSQC and HMBC).
The free radical scavenging effect of the n-butanol extract has been evaluated using DPPH method
