Peel Extract

Methicillin-resistant Staphylococcus aureus (MRSA) is the most common bacteria causing nosocomial infections with high levels of resistance to available antibiotics. So, it is necessary to search for new compounds to solve this problem. Various studies showed antibacterial activity of rambutan peel but for Rambutan Binjai peel extract that are from Indonesia has never been studied against the MRSA. This study aims to determine the antibacterial activity, the value of minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) using agar diffusion method. The concentration of rambutan peel ethanol extract at as much as 62.5 mg/ml showed the inhibitory diameter i.e 21.3 ± 2.4 mm. MIC and MBC were in the same range, which was between 0.98 (mg/ml) to 1.95 (mg/ml). The activity strength of tetracycline against the extract was at 1:50. This revealed that Rambutan Binjai peel extract had great potency as antibacterial agent to MRSA. Dhaka Univ. J. Pharm. Sci. 17(2): 197-203, 2018 (December)

Scrophularia. striata from Scrophulariacea family has been used in Iranian folk medicine for the treatment of infectious diseases. In this study we evaluated the synergistic effect of S. striata   hydroalcoholic extract (SSE) and commercially available antibiotics against P. aeroginosa and Methicillin- resistant Staphylococcus aureus (MRSA). The resazurin-based microdilution method was used to determine the minimum inhibitory concentration (MIC) values of plan extract and standard antibiotics. The interaction between standard antibiotics and SSE was evaluated by using checkerboard method. The results of this study revealed that SSE enhance the antibacterial activity of antibiotics. The combination of SSE and Vancomycin had synergistic to additive effects against MRSA.  SSE in combination with Gentamicin had synergistic to additive effects against P. aeruginosa. The interaction between Ceftazidime and SSE was additive against P. aeruginosa.  The best result was the synergistic effect between SSE and Piperacillin-Tazobactam against P. aeruginosa. In conclusion the results of this research indicated that S. striata has the potential to enhance the antibacterial activity of antibiotics and could be a source to the designing new compounds with synergistic effect in combination with standard antibiotics.

This study aimed to determine the in vitro antibacterial activities of essential oil from cinnamon bark (Cinnamomum burmannii) on Methicillin-resistant Staphylococcus aureus (MRSA) isolated from raw milk. Essential oil from cinnamon bark obtained from the steam distillation method and essential oil was made in a series dilution with a concentration of 1%, 2%, 4%, and 8%. The antibacterial activities were tested using the disk diffusion method. Results showed from five isolates of MRSA, one isolate was sensitive of essential oil with a concentration 2% and all of the isolate was sensitive with a concentration 4% and 8%. The antibacterial activity showed by inhibition zones on  MRSA. The results suggest that the activity of the essential oils of cinnamon bark has an antibacterial effect on MRSA and it is developed as phytopharmaca.

Methicillin-resistant Staphylococcus aureus (MRSA) is a pathogen that becomes the main concern since it is a multidrug-resistant organism and causes high morbidity and mortality. This study aimed to investigate the antibacterial activity of ethanolic extract of Phaleria macrocarpa leaves, peel, and fruit flesh on MRSA. This study was an experimental laboratory study with a post-test only control group design to assess the antibacterial activity of ethanolic extract from leaves, peel, and fruit flesh of Phaleria macrocarpa against MRSA ATCC 43300 and MRSA clinical isolates using a disk diffusion method. Extracts from the leaves, peel, and flesh of Phaleria macrocarpa had potential as an antibacterial agent against MRSA ATCC 43300 at a concentration of 40%, although not yet equivalent to antibiotic control. The ethanol extract of Phaleria macrocarpa peel at a concentration of 30-40% had potential as an antibacterial agent against MRSA clinical isolates, although not yet equivalent to antibiotic control. Further research needs to be performed so that Phaleria macrocarpa extract can be a potential source of subsequent antibacterial development against MRSA.
