“…The organism inhibited is Salmonella species, Bacillus species, and the concentrations vary according to the organisms. 24 The microbicidial activity of P. guajava is attributable to guajaverine and to psydiolic acid. The active flavonoid compound guaijaverin extracted from the leaves of the same plant is reported to have high potential antiplaque activity.…”

Searches for substances with antimicrobial activity are frequent, and medicinal plants have been considered interesting by some researchers since they are frequently used in popular medicine as remedies for many infectious diseases. The aim of this study was to verify the synergism between 13 antimicrobial drugs and 8 plant extracts -"guaco" (Mikania glomerata), guava (Psidium guajava), clove (Syzygium aromaticum), garlic (Allium sativum), lemongrass (Cymbopogon citratus), ginger (Zingiber officinale), "carqueja" (Baccharis trimera), and mint (Mentha piperita) -against Staphylococcus aureus strains, and for this purpose, the disk method was the antimicrobial susceptibility test performed. Petri dishes were prepared with or without dilution of plant extracts at sub-inhibitory concentrations in Mueller-Hinton Agar (MHA) In a constant attempt to improve their quality of life, men have used plants as source of food, shelter, clothing, medicine, cosmetics, and for seeking relief from hardship of life. Some plants are known as medicinal because they contain active substances that cause certain reactions, from relenting to the cure of diseases, on the human organism (Silva Junior et al. 1994). Knowledge on medicinal plants sometimes means the only therapeutic resource of some communities and ethnic groups (Di Stasi 1996); and their use, especially in South America, contributes significantly to primary health care (Holetz et al. 2002). Infectious diseases still represent an important cause of morbidity and mortality among humans, especially in developing countries. Even though pharmaceutical industries have produced a number of new antimicrobial drugs in the last years, resistance to these drugs by microorganisms has increased. In general, bacteria have the genetic ability to transmit and acquire resistance to drugs used as therapeutic agents (Nascimento et al. 2000).In vitro studies on plants used in traditional medicine have been carried out in the field of microbiology, especially on pathogenic bacterial growth; and some of these studies were about the antimicrobial activity of Mikania glomerata Spreng ("guaco") (Boyayan 2002, Holetz et al. 2002, Psidium guajava L (guava) (Gnan & Demello 1999, Jaiarj et al. 1999, Nascimento et al. 2000, Ahmad & Beg 2001, Abdelrahim et al. 2002, Holetz et al. 2002, Voravuthikunchai et al. 2004, Qadan et al. 2005, Syzygium MATERIALS AND METHODSPlant samples -M. glomerata, P. guajava, B. trimera, M. piperita, and C. citratus samples were collected in 2004 from an experimental field of the School of Agronomical Sciences, Unesp, Botucatu, São Paulo, Brazil, and the voucher specimens were deposited at the Herbarium of the Department of Botany, Institute of Biosciences, Unesp. Their leaves were dried at 40 o C and triturated in a mechanical mill. A. sativum, S. aromaticum, and Z. officinale samples were obtained from the local commerce in the same year and were used in natura for the extracts preparation.

“…Tannins have been found to form irreversible complexes with proline-rich proteins resulting in the inhibition of the cell protein synthesis (Hagerman and Butler, 1981). The methanolic extract of Psidium guajava was also shown to possess antibacterial effect on Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa 5 . As per several findings in the literature a number of higher plants have been explored to exhibit antimicrobial activity due to the presence of tannins 11,12,13 .…”

The antimicrobial activities of Psydium guajava leaf extracts against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa and acne-developing organisms is reported 5 . Traditionally the ash of burned leaves of Mangifera indica Linn is used as household remedy for burns and scalds.…”

ABSTRACT:The objective of this study was to evaluate the possible antimicrobial properties of water, methanol, chloroform and Petroleum ether extracts of leaves of different Indian medicinal plants including Mangifera indica Linn, Ixora parviflora Vahl, Psydium guajava Linn, Calotropis procera Ait. The extracts were investigated individually for in vitro antibacterial activity by cup plate (well diffusion) method against nine pathogenic bacteria cultures. Of all the plants investigated for antimicrobial potential, the leaf extracts of Psydium guajava showed high antimicrobial activity against the tested microorganisms. Methanolic leaf extract of Psydium guajava was found to exhibit highest antimicrobial activity. Water leaf extracts of Mangifera. Indica and Ixora parviflora did not show antimicrobial activity. Phenolic content of Psydium guajava could contribute towards its antibacterial activity. The antibacterial activities of the investigated plants could make it useful in microbial infections.
