Antibacterial activity of medicinal plant extracts against periodontopathic bacteria

Abstract

This study was performed to evaluate the antibacterial activity of Althaea officinalis L. roots, Arnica montana L. flowers, Calendula officinalis L. flowers, Hamamelis virginiana L. leaves, Illicium verum Hook. fruits and Melissa officinalis L. leaves, against anaerobic and facultative aerobic periodontal bacteria: Porphyromonas gingivalis, Prevotella spp., Fusobacterium nucleatum, Capnocytophaga gingivalis, Veilonella parvula, Eikenella corrodens, Peptostreptococcus micros and Actinomyces odontolyticus. The methanol extracts of H. virginiana and A. montana and, to a lesser extent, A. officinalis were shown to possess an inhibiting activity (MIC < or = 2048 mg/L) against many of the species tested. In comparison, M. officinalis and C. officinalis extracts had a lower inhibiting activity (MIC > or = 2048 mg/L) against all the tested species with the exception of Prevotella sp. Illicium verum methanol extract was not very active though it had a particular good activity against E. corrodens. The results suggest the use of the alcohol extracts of H. virginiana, A. montana and A. officinalis for topical medications in periodontal prophylactics.

Antimicrobial activity of the essential oil from Lippia sidoides, carvacrol and thymol against oral pathogens

“…Oral pathogens have been recently tested for antimicrobial susceptibility to a number of plant extracts and natural substances (7,8).…”

“…The prevalence and incidence of oral diseases, coupled with the resultant social and economic implications, has led to a constant striving to produce safer substances for the development of new natural antimicrobial agents (6,7). In fact there is an overwhelming number of studies on the biological activities of plants and their natural product derivatives (8)(9)(10).…”

Study of the Antibacterial Activity of Methanolic and Aqueous Extracts of Myrtus communis on Pathogenic Strains Causing Infection

“…Iauk et al [21] also showed that the higher the concentrations of the Vernonia amygdalina, the larger the diameter of the bacterial growth inhibition zones.…”

A Novel Eudesmane Glycosides Sesquiterpene from <i>Calendula</i> <i>officinalis</i> L.

“…In the Flora of Syria, this genus is represented by 8 species [1]. Previous studies demonstrated therapeutic potentialities of Calendula officinalis L. such as anti-inflammatory activity [2][3][4][5], immunomodulatory [6][7], Hepatoprotective [8], wound-healing [9], antioxidant [10][11][12], antibacterial and antiparasitic activity [13][14][15][16]. The essential oil from C. officinalis has been also investigated [17][18][19][20][21][22].…”
