“…It was susceptible only to benzoic acid and cinnamic acid. On the other hand, P. aeruginosa (11), which is also resistant to different antibiotics, had its growth inhibited by the extracts from clove, jambolan, pomegranate and thyme. Such results are very interesting, because this bacterium was isolated from a hospital environment and its control is very difficult by therapeutic means.…”

The antimicrobial activity of plant extracts and phytochemicals was evaluated with antibiotic susceptible and resistant microorganisms. In addition, the possible synergistic effects when associated with antibiotics were studied. Extracts from the following plants were utilized: Achillea millifolium (yarrow), Caryophyllus aromaticus (clove), Melissa offficinalis (lemon-balm), Ocimun basilucum (basil), Psidium guajava (guava), Punica granatum (pomegranate), Rosmarinus officinalis (rosemary), Salvia officinalis (sage), Syzygyum joabolanum (jambolan) and Thymus vulgaris (thyme). The phytochemicals benzoic acid, cinnamic acid, eugenol and farnesol were also utilized. The highest antimicrobial potentials were observed for the extracts of Caryophyllus aromaticus and Syzygyum joabolanum, which inhibited 64.2 and 57.1% of the tested microorganisms, respectively, with higher activity against antibiotic-resistant bacteria (83.3%). Sage and yarrow extracts did not present any antimicrobial activity. Association of antibiotics and plant extracts showed synergistic antibacterial activity against antibiotic-resistant bacteria. The results obtained with Pseudomonas aeruginosa was particularly interesting, since it was inhibited by clove, jambolan, pomegranate and thyme extracts. This inhibition was observed with the individual extracts and when they were used in lower concentrations with ineffective antibiotics.

Essential oil from yarrow (Achillea millefolium L. s. l.) has a broad spectrum of pharmacological activities. However, active chemical components of yarrow oil are sensitive to environmental factors such as, light, oxygen and temperature. Encapsulation of essential oil offers solutions for the limitation. Yarrow oil was encapsulated in hydroxypropyl-β-cyclodextrin (HPβCD) through freezedrying technique with encapsulation efficiency of 45%. Inclusion complex formation was examined by scanning electron microscope, Fourier transformed infrared spectroscopy and UV-vis analysis and phase solubility study. Yarrow oil gave strong antioxidant activity of 72% DPPH scavenging at 50 μg/mL. HPβCD could protect active compounds of essential oil and retained antioxidant activity after sunlight exposure. Yarrow oil also exhibited antibacterial activity against Staphylococcus aureus and Escherichia coli with the minimum inhibitory concentration (MIC) values of 250 μg/mL and 500 μg/mL, respectively. The antibacterial efficacy was much improved after encapsulation against both S. aureus and E. coli with the MIC value of 62.5 μg/mL.Encapsulación de aceite esencial de milenrama en hidroxipropil-beta-ciclodextrina. Caracterización fisicoquímica y evaluación de bioeficiencia. RESUMENEl aceite esencial de la milenrama (Achillea millefolium L. s. l.) presenta un amplio espectro de actividades farmacológicas. Sin embargo, los componentes químicos activos del aceite son sensibles a factores ambientales tales como, luz, oxígeno y temperatura. La encapsulación del aceite esencial ofrece soluciones para esta limitación. El aceite se encapsuló en hidroxipropil-β-ciclodextrina (HPβCD) mediante la técnica de liofilización con un rendimiento del 45%. La formación del complejo de inclusión se analizó mediante técnicas de SEM, FT-IR y UV-vis y se realizó un estudio de solubilidad. El aceite presentó una fuerte actividad antioxidante de 72% de DPPH. HPβCD protege los compuestos activos de aceite esencial y retoene la actividad antioxidante después de la exposición a luz solar. El aceite también exhibió actividad antibacteriana contra Staphylococcus aureus y Escherichia coli con valores mínimos de concentración inhibitoria (MIC) de 250 μg/mL y 500 μg/mL, respectivamente. La eficacia antibacteriana mejoró mucho después de la encapsulación contra S. aureus y E. coli con un valor de CIM de 62,5 μg /ml. ARTICLE HISTORY
