essential oils are volatile, natural, complex compounds formed by aromatic plants as secondary metabolites. in nature, essential oils play an important role in protecting plants in form of antibacterials, antivirals, antifungals, insecticides properties and also against herbivores. they also may attract some insects to use them in dispersion of pollens and seeds, or repel undesirable others. pr...

Glycoproteins were extracted from membranes of erythrocytes that displayed Tn polyagglutination and were compared chemically and immunologically with glycoproteins of group O, MN cells. Tn glycoprotein had lower than normal NANA : protein and sugar : protein ratios, as revealed by direct analysis and polyacrylamide gel electrophoresis, and displayed slower immunoelectrophoretic mobility than gl...

BACKGROUND The current chemotherapy for cutaneous leishmaniosis (CL) has a series of drug limitations such as toxic side effects, long duration, high costs and drug resistance, which requires the development of new drugs or effective alternatives to the CL treatment. Essential oils (EOs) are complex mixtures of secondary metabolites from various plants. It has been shown that several EOs, or th...

This paper presents an analysis of the morphological and anatomical characteristics aboveground parts (herba) clary sage (Salvia sclarea L.), with emphasis on investigation its surface structures. After procedure primary processing drying plant material, it was determined that composition crushed herbal drug Salviae sclareae herba showed presence leaves, bracts, flowers axis inflorescence, stem...

The mineral contents of roots, leaves, stalks, and inflorescences the aromatic plant species Anethum graveolens L., Coriandrum sativum Lavandula angustifolia Mill., Levisticum officinale W.D.J. Koch, Salvia sclarea L. were studied by means neutron activation analysis. 36 major trace elements determined biological transfer coefficients calculated. Among minor elements, K with a content in range ...
