Jurnal Teknologi Laboratorium
Alfa mangostin, gamma-mangostin and xanthone group compounds are secondary metabolites contained in mangosteen (G. mangostana L.) which can be isolated from the fruit, bark, leaves and rind of mangosteen. All three compounds were shown to inhibit stronger against Mycobacterium tuberculosis. Alfa mangostin also active against Staphylococcus aureus and Enterococcus bacteria that are resistant to vancomisin and methicillin. Objective of this study to determine the antibacterial activity of
... extract of mangosteen rind against Staphyllococcus aureus and Escherechia coli in vitro. Antibacterial activity test used is the diffusion wells and paper disc diffusion method. The test results obtained antibacterial activity of methanol extract of mangosteen rind can inhibit the growth of Staphyllococcus aureus at a concentration of 16%, but below its resistance zone diameter Cyprofloxacin. As against Escherichia coli, the methanol extract of mangosteen rind could not inhibit the growth of bacteria.
