mulberry pyralid, glyphodes pyloalis walker is an important pest on mulberry. the essential oil of rosemary rosemarinus officinalis l. (lamiales: lamiaceae) has been investigated on toxicity and physiological characteristics of this moth under controlled conditions. the major compounds of the oil were analyzed as 1, 8 cineol (20.021%), borneol (7.17%), camphor (6.541%), geraniol (6.281%), camph...

Six medicinal plants Helichrysum italicum (Roth) G. Don, Angelica archangelica L., Lavandula officinalis L., Salvia officinalis L., Melilotus officinalis L., and Ruta graveolens L. were used. The aim of the study was to compare their extracts obtained by Soxhlet (hexane) extraction, maceration with ethanol (EtOH), and supercritical CO2 extraction (SC-CO2) targeted on coumarin content (by high p...

Rosemary (Rosemarinus officinalis L.) is a well-known medicinal and essential oil plant, utilized by humankind since ancient times. The objective was to determine the effect of steam distillation time (DT) and material (dry or fresh biomass) on essential oil yield, composition, and bioactivity; and to develop regression models that can predict oil yield and composition at specific DT. The oil y...

In this study, Rosmarinus officinalis L. essential oil and three of its main components 1,8-cineole (27.23%), α-pinene (19.43%) and β-pinene (6.71%) were evaluated for their in vitro antibacterial activities and toxicology properties. R. officinalis L. essential oil possessed similar antibacterial activities to α-pinene, and a little bit better than β-pinene, while 1,8-cineole possessed the low...

INTRODUCTION In cirrhosis some toxic substances accumulate in brain and modify the expression of several neuronal receptors. Thus, the use of medicinal plants such as Rosmarinus officinalis L. has been proposed in several pathologies due to its hepatoprotective, antioxidant and neuroprotective activity. In this study we evaluated the expression of the subunits NR1, NR2A and NR2B of the glutamat...

Antioxidant activity of Avicenni marina L and Avicennia officinalis L fruit extracts in ethyl acetate, acetone, methanol and ethanol were studied by ABTS, CrO5 and FRAP method. All the extracts possessed significant amount of the antioxidant activity, extracts in methanol and ethanol was demonstrated convincingly higher antioxidant activity by all the three methods. Whereas, the ethyl acetate e...

BACKGROUND/OBJECTIVES Carnosic acid (CA), found in rosemary (Rosemarinus officinalis) leaves, is known to exhibit anti-obesity and anti-inflammatory activities. However, whether its anti-inflammatory potency can contribute to the amelioration of obesity has not been elucidated. The aim of the current study was to investigate the effect of CA on Toll-like receptor 4 (TLR4) pathways in the presen...
