Organic and aqueous solvent extracts of Arctotis auriculata Jacq., Eri
ocephalus africanus L., Felicia erigeroides DC., and Helichrysum crisp
um (L.) D. Don, were investigated for selective antimicrobial activiti
es. Organic extracts of A. auriculata and H. crispum inhibited the gro
wth of Mycobacterium smegmatis. The same extracts, together with organ
ic extracts of F. erigeroides, were active against Pseudomonas aerugin
osa. Antifungal activities against Candida albicans were exhibited by
organic extracts of E. africanus, F. erigeroides, and H. crispum. Orga
nic extracts of A. auriculata and E. africanus, as well as the aqueous
extract of the latter plant, were active against Staphyllococcus aure
us.
