background: cumin ( cuminum cyminum l . [family apiaceae]) seed essential oil is reported to have antiseptic activity. until now the antiviral properties of cumin seed extracts on viruses such as herpes simplex virus-1 (hsv-1) have not been studied. the objective of this study was to investigate the in vitro effects of aqueous, methanolic and hydroalcoholic extracts of cumin seed on hsv-1 growt...

Aqueous and ethanolic extracts obtained from nine Chilean marine macro-algae collected at different seasons were examined in vitro and in vivo for properties that reduce the growth of plant pathogens or decrease the injury severity of plant foliar tissues following pathogen infection. Particular crude aqueous or organic extracts showed effects on the growth of pathogenic bacteria whereas others...

Background & Aim: During human history, most of infectious diseases have been cured with herbal drugs traditionally so that, nowadays, in most developing countries, herbal drugs play an important role in primal remedy. This study has been done according to the appropriate climate and biodiversity of plants in Golestan province in order to investigate the antimicrobial activity of alcoholics, aq...

Aqueous, ethanolic and hexane extracts of the leaves of Nauclea latifolia (Rubiaceae) were assessed for their fasting blood glucose lowering effect in normoglycaemic and streptozotocin-diabetic rats. Wistar strain albino rats were given different doses of the extracts after 18 hrs fast and their blood glucose measured at 0, 1, 2, 4 and 6 hours after treatment. The aqueous and ethanolic extracts...

The effect on aqueous and alcoholic extracts of the leaves of Sencio nudicaulis Buch. Ham. was studied on the spontaneous movements of the whole worm and nerve-muscle preparation of Setaria cervi and on the survival of micro-filariae in vitro. Aqueous as well as alcoholic extracts caused inhibition of spontaneous motility of the whole worm and nerve-muscle preparation of S. cervi characterized ...

BACKGROUND Plant polyphenols are known for their limiting of adverse effects on reactive oxygen species (ROS) in biological systems. The photochemiluminescence (PCL) assay allows to evaluate the antiradical activity of a compound in the presence of a superoxide anion-radical (O •-), which is one of the ROS directly associated with the human body. In this work, determination of the superoxide an...

Introduction and objective: Brucellosis is a zoonosis disease among animal and human, and has been endemic in Iran. The most important virulence factors of Brucella are related to their capability of intraphagocytic survival. Because of the side effects of brucellosis treatment regime, it is necessary to find new antimicrobial agents. The hop plant (Humulus lupulus) extract reported as having a...

To understand the impacts of different processing methods on the composition and effects of the herb Saussurea laniceps (SL), the present study report the first comparison of the chemical constituents of aqueous and ethanolic SL extracts using chromatographic analysis, and to compare their pharmacological effects in a mouse anti-inflammatory, anti-nociceptive model and an in vitro anti-oxidant ...

Background:The relaxant and anticholinergic (functional antagonism) effects, histamine H1 inhibitory effect, and calcium channel blocking effect of Nigella sativa have been demonstrated on guinea pig tracheal chains.  Several therapeutic effects including anti-asthma and dyspnea have also been ascribed to the seeds of Nigella sativa. Objective: To evaluate the antitussive effect of this plant. ...

The effect produced by neem seed extracts and a neem seed concentrate (NSC) on the mortality and development of Heterodera glycines was evaluated. Second-stage juvenile (J2) mortality produced by the extracts and NSC was determined. Soybean seedlings treated with each of the extracts (aqueous, methanolic and hexane) were inoculated with J2 and the number of females and eggs per root system dete...
