Abstract

Annona muricata or which commonly known as soursop is from the family
Annonaceae and it is used globally as a traditional medicine to heal small wound
and disease cause by pathogens. The fruits, seeds, barks, leaves, and even roots
have been used to treat external and internal infection, coughs, liver ailments,
inflammation, diabetes, and extractions from the leaves have been widely used to
kill pest. This study was conducted to determine the phytochemical constituent
present in Annona muricata using methanol and hexane solvent and to determine
antimicrobial property against Gram positive and Gram negative bacteria.
Methanol showed the highest percentage yield of crude extract with 8.38% and for
hexane only 0.26%. Phytochemical screening test was done with the methanol
extract showed the presence of alkaloids, flavonoids, saponins, and tannins.
Meanwhile for hexane extract showed the presence of saponins and tannins only.
Methanol and hexane extracts were used against four types of bacteria species
which are Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae and
Pseudomonas aeruginosa. The antimicrobial activities were tested using four
different concentrations of extracts; 25 mg/ml, 50 mg/ml, 100 mg/ml and 200
mg/ml to determine the inhibition zone of bacteria. Results showed that only
methanol extract have antimicrobial property against Staphylococcus aureus,
Bacillus subtilis, Klebsiella pneumoniae and Pseudomonas aeruginosa.
