  2. bnot applicable: for MF as not tested for antioxidant activity and cytotoxicity, mg equivalent could not be detected for non-antioxidant compounds.
  3. cnot tested due to low yield of the compound.
  4. dpositive drug control where tetracycline for antibacterial, vitamin C for antioxidant, actinomycin D for cytotoxicity.
