Essential oil of Baru Cina leaves (Artemisia vulgaris L.) has been successfully isolated by hydrodistillation method using the Stahl apparatus. were for ± 6 hours to produce essential amount 0.39 % (v/b). The obtained from was characterized GC-MS spectroscopy. analysis results showed that there 29 compounds and main identified as many 14 compounds, such Alpha-Pinene (0.33%), 1,8-Cineol (1.96% )...

A polar fraction obtained from banana fruit pulp by high-vacuum distillation / solvent extraction (pentane-dichloromethane, 2 + 1) and subsequent liquid chromatography on silica gel was derivatized with isopropylisocyanate. Separation of enantiomers of heptan-2-ol and Z-4-hepten-2-ol was performed via their carbamates by means of multidimensional gas chromatography using an achiral (D B -5, col...

Streptomyces spp. have the ability to produce a wide variety of secondary metabolites that interact with the environment. This study aimed to discover antifungal volatiles from the genus Streptomyces and to determine the mechanisms of inhibition. Volatiles identified from Streptomyces spp. included three major terpenes, geosmin, caryolan-1-ol and an unknown sesquiterpene. antiSMASH and KEGG pre...

We have investigated the expression of integrins by rat oligodendroglia grown in primary culture and the functional role of these proteins in myelinogenesis. Immunochemical analysis, using antibodies to a number of alpha and beta integrin subunits, revealed that oligodendrocytes express only one detectable integrin receptor complex (alpha OL beta OL). This complex is immunoprecipitated by a pol...

The volatile constituents of the aerial parts of vervain (Verbena officinalis L.) cultivated locally were investigated. Analysis of the volatile fraction by GC and GC-MS is described. Compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).
