About the Book

La présente étude démontre l'influence du solvant d'extraction sur le rendement d'extraction, les constituants phytochimiques, les propriétés antioxydantes, antimicrobiennes et cytotoxiques des différents extraits isolés des parties du rhizome d'Hedychium coronarium. Tous les extraits présentaient une large gamme de contenu phénolique total et de contenu flavonoïde total, respectivement. Une analyse GC-MS a été réalisée pour déterminer les phytoconstituants des différents extraits. Parmi les extraits de solvant, l'extrait de méthanol a montré la plus forte activité DPPH, ABTS et pouvoir réducteur. L'essai de bioautographie par CCM a également confirmé que l'extrait méthanolique avait les bandes antioxydantes actives les plus élevées par rapport aux autres extraits. Une bonne corrélation a été observée entre les valeurs IC50 des tests antioxydants et le contenu phénolique et flavonoïde total. Les extraits de H. coronarium ont été examinés pour leur activité antimicrobienne contre 5 souches bactériennes et 4 souches fongiques. Les résultats ont montré que l'extrait méthanolique présentait la concentration inhibitrice minimale la plus faible et la plus grande zone d'inhibition contre Candida albicans. La forte activité cytotoxique contre la lignée cellulaire Hela a été obtenue pour les extraits méthanoliques.
