Task: Answer Verification
Input (English): Question: Do some Strychnos spinosa ( Loganiaceae ) leaf extracts and fractions have good antimicrobial activities and low cytotoxicities?
Answer: The acetone extract and the chloroform fraction had the highest antibacterial activity. By solvent-solvent fractionation it was possible to increase the activity against A. fumigatus and to decrease the cytotoxicity leading to a potentially useful product to protect animals against aspergillosis. Our results therefore support the use of S. spinosa leaves in traditional medicine to treat infectious diseases.
Output (English): yes
