|dc.description||This report is concerning the phytochemical study of two Algerian plants belonging to the Fabaceae family (Genista ulicina Spach) and Asteraceae family (Chrysanthemum macrocarpum Coss. & Kralik ex Batt). This study led to the isolation and identification of 36 compounds from which 10 compounds are new.
The structures of isolated compounds were established particularly by the use of NMR highfield
1D and 2D technics (1H, 13C J-modulated, COSY H-H, HSQC J-modulated, HMBC and NOESY), high resolution mass spectrometry (ESI-MS and HR-ESI-MS), measurement of rotatory power and comparison with literature data.
GC and GC / MS analyses of the essential oil of C. macrocarpum showed that it was mainly represented by: T-cadinol (19.6%), spathulenol (12.5%), caryophyllene oxide (6.5%), and α- cadinol (5.6%).
The chloroform fraction of C. macrocarpum showed a weak antibacterial activity against: E.
coli, S. aureus, P.aeruginosa, E. faecalis and K. pneumoniae.
The same chloroform fraction was evaluated for its antiproliferative activity against human cancer HT-29 cells and human PC3 cells. The results indicate that the chloroform fraction inhibited cell proliferation of both HT-29 and PC-3 cells,The chloroform fraction showed an excellent analegesic, anti-inflammatory and antiulcerogenic activities.
The butanolic fraction of G. ulicina and isolated compounds were investigated for their antibacterial and antiproliferative growth inhibition, but no significant activities were observed.||
