ANTIMICROBIAL ACTIVITIES OF DOCYNIA INDICA FRUIT EXTRACTS
Hien Chau and Tu Nguyen*
ABSTRACT
Docynia indica (D. indica) is a tree species that is widely distributed and traditionally used as a source of natural preservatives and a medicinal supplement in some Asian countries. In this study, the extract of D. indica dried fruit was obtained using 40% methanol as an extraction solvent. The extracts of the D. indica fruits were obtained using two different extraction methods: steam distillation method and decoction method. The antimicrobial activity of the extract was evaluated based on the measurement of inhibition zone diameters. 3 Gram-positive bacterial strains being Staphylococcus aureus ATCC 25923, Micrococcus luteus ATCC 9341 and Bacillus cereus ATCC 6633 and 3 Gram-negative bacterial strains being Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853 and Vibrio parahaemolyticus ATCC 17802 were selected as the test Keywords: Docynia indica; antimicrobial; Staphylococcus aureus ATCC 25923; Micrococcus luteus ATCC 9341; Bacillus cereus ATCC 6633; Escherichia coli ATCC 25922; Pseudomonas aeruginosa ATCC 27853; Vibrio parahaemolyticus ATCC 17802.
