Background: Increased microbial resistance to conventional medicines and their side effects have led to studying the effect of herbal extracts on microorganisms.

Objectives: The current study aimed at evaluating the antimicrobial activity of total extract and fractions of chloroform, methanol, and aqueous of aerial parts of Salvia aegyptiaca.

Methods: The plants were collected from Bandar Abbas, Iran, in April 2015. The methanol extract of aerial parts, in addition to chloroform, methanol, and aqueous fractions, were prepared by the maceration method from S. aegyptiaca. The antimicrobial activity of fractions were determined by cup plate and further micro-dilution methods based on the Clinical and Laboratory Standards Institute (CLSI) 2013 against some Gram-positive and -negative bacteria as well as Candida albicans. Statistical analysis was conducted by t test.

Results: Significant results were obtained regarding the tested microorganisms only by micro-dilution method.

Conclusions: There were no significant results in plant extract and its fractions against the tested microorganisms in the cup plate method, which may be due to the inability of agar diffusion. In contrast, by excluding the agar’s hindrance property, verified results of micro-dilution method were deleted.
