Abstract

Objective: To determine and compare the effect on antimicrobial potency of crude stems extract of Adenium obesum (A. obesum) by Soxhlet and maceration extraction methods. Methods: The crude extracts were prepared from the coarse samples of stems with methanol by using Soxhlet and maceration extraction methods. Both the crude extracts from two extraction methods were dissolved in water and successively extracted by different polarities solvents with increasing polarities. In vitro antimicrobial potency of different polarities crude extracts obtained from Soxhlet and maceration methods was determined by agar gel diffusion method against different food borne pathogenic bacterial strains. Results: The results for antimicrobial potency of different crude extracts were almost similar by Soxhlet and maceration and methods. The average range of inhibition potency of different polarities crude extracts was 0%-17% by Soxhlet method and inhibition potency 0%-24% by maceration method. Conclusions: These results obtained from in vitro approach give promising basic information about this plant as well as some potential crude extracts can be used for the treatment of infectious diseases.
