The steroidal saponin-containing fraction from methanolic extract of Dracaena fragrans was tested for molluscicidal and ovicidal activities against Biomphalaria alexandrina and Bulinus truncatus and showed significant increase in total protein content & albumen, in aminotransferases and acetylcholinesterase activities.
Flavonoids from Albizia chinensis of Egypt
The first three isolates were tested for their antimicrobial activity and the results revealed that the tested compounds exhibited moderate inhibiting activity against grampositive and gram-negative bacteria while no antifungal activity was observed.
