Spectral analyses of fresh and dry Hypericum perforatum L. Effects with colloidal nano silver 30 ppm

Spectral analyses of 1% water extracts of fresh and dry Hypericum perforatum L. and 1% dry H. perforatum with colloidal nano silver (NSPs) 30 ppm were conducted. The nano silver is standardised and patented by the Swiss company Evodrop. Non-equliblrium energy spectrum (NES) and Differential non-equliblrium energy spectrum (DNES) methods were used for the spectral analysis. A comparative analysis of 1% extracts of fresh and dry H. perforatum was performed in order to determine the local extremums for effects of nerve tissue conductivity at (-0.1112) eV, anti-inflammatory (-0.1212) eV, anti-tumor effects (-0.1387) eV. The results showed stimulating effect on the nervous system and improvement of nerve conduction (local extremums E=-0.1112 eV)(?=11.15 ?m) (?=897 cm-1), as well as anti-inflammatory effect (E = -0.1212 eV)( ?=10.23 ?m) (?=978 cm-1) and inhibition of development of tumor cells at a molecular level (E=-0.1387 eV) (?=8.95 ?m) (?=1117 cm-1). It was found that clusters of 16 and 15 water molecules are formed in the water herbal extracts of fresh H. perforatum and of dry H. perforatum with AgNPs 30 ppm. The fresh plant showed better results then the dry one. The addition of colloidal nano silver 30 ppm led to better results of the drug.

Visual Orthophoto Classification Application

Data acquisition using remote sensing has opened up new possibilities of their analysis and application. For the ecological stability calculations, it is needed to divide the observed area into subsections based on the land character. The selection may be done by various kinds of processing. For example, it may be done manually, but to increase the post-processing effectivity, it is necessary to find faster, automatic ways of the post-processing. Many software environments are able to solve this problematic by using spectral analyses and appropriate tools.

A New Pentacyclic Triterpenoid from Albizia lebbekoides (DC) Benth (Leguminosae)

Albizia lebbekoides (DC) Benth is one of the five species of the genus Albizia found in the Philippines. Not much is known about the chemistry and potential uses of this species. Solvent partition followed by sequential and repeated liquid chromatographic purification over silica led to the isolation of a compound from the hexane extract of A. lebbekoides leaves. A review of related literature and spectral analyses showed that the isolated compound is a new pentacyclic triterpenoid with an oleanane skeleton. Its structure was determined as 3β, 16α-dihydroxyolean-6(7),12(13)-dien-28-oic acid.

2,2-Bis(phenylselanyl)-1-(p-tolyl)vinyl 2-Oxo-2-(p-tolyl)acetate

2,2-Bis(phenylselanyl)-1-(p-tolyl)vinyl 2-oxo-2-(p-tolyl)acetate was synthesized via the reaction of p-tolylacetylene with diphenyl diselenide and benzoyl peroxide in benzene under atmospheric conditions. The molecular structure of the synthesized compound was evaluated using single-crystal X-ray analysis and spectral analyses. The process reported here provides a rare example of the direct and selective transformation of a terminal alkyne to the corresponding geminal diseleno-substituted alkene.
