Abstract

Antimicrobial potency test of ethanol extracts of Avocado cortex (Persea Americana Mill.) has been conducted against Staphylococcus aureus and Pseudomonas aeruginosa. Avocado cortex was extracted by reflux method using ethanol 80%. The antimicrobial activity was determined using agar disc diffusi~n method (kirby~bauer test}. The extracts was considered as high antibacterial potency if it has zone of inhibition of 14 mm or greater. This research has shown that the concentration of 30 % , 40 % and 50 %of the extracts can inhibit the growth of Pseudomonas aeruginosa ATCC 25922 with an average zone - of inhibition respectively 14.0666 mm; 17.6700 mm; and 20.4932 mm and the concentration of 40% and 50 % of the extracts also can inhibit the growth of Staphylococcus aureus ATCC 25923 with an average zone of inhibition16,4198 mm; dan 20,4598 mm. 50% of the ethanol extracts of avocado cortex showed the highest zone of inhibition against both of bacteria and almost equal to the inhibition of gentamicin as a positive control. Therefore, this study has shown that the ethanol extract of Avocado cortex has a high potential as an antibacterial against both of bacteria.
