The extracts were screened for antibacterial activity against Gram positive (Staphylococcus aureus,Corynebacterium diphteriae) and Gram negative (Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Salmonella typhi) bacteria, and for toxicological activity towards the brine shrimp (Artemia salina). The results are tabulated. Many of the species tested showed antibacterial activity against Staphylococcus aureus and Corynebacterium diphteriae, and a few against other bacteria. Toxicological activity was tested at 3 extract concentrations: some activity was demonstrated for nearly all species, and LD50 values are given for the most active extracts.
