In our continued investigations of the plant Caryopteris incana, five new iridoid glucosides 1-5, including two cis-trans-isomers, 3 and 4, along with six known compounds 6-11, were isolated from the n-butyl alcohol (n-BuOH) soluble fraction of whole dried material of Caryopteris incana. Their structures were established by a combination of spectroscopic techniques, including 1D and 2D NMR and ...

INTRODUCTION Since Pall-German stopped manufacturing ITLC-SG, it has become necessary to validate alternative stationary phases. OBJECTIVE To validate different stationary phases versus ITLC-SG Pall-Gelman in the determination of the radiochemical purity (RCP) of (111)In-pentetreotide ((111)In-Octreoscan) by planar chromatography. MATERIAL AND METHODS We conducted a case-control study, whic...

Various studies on Phragmanthera incana (mistletoe) did not intensify toxicity. Toxicological evaluation of Phragmanthera incana, a species of mistletoe growing on two plant hosts namely Cocoa (Theobroma cacao) and Kolanut (Cola nitida) in South-western Nigeria was carried out with the observation of Wistar rats’ haematological and serum biochemical changes for a period of thirty-day administra...

Levels of biologically active and reserve substances were investigated in the leaves rhizomes Paeonia anomala L., P. hybrida Pall., lactiflora Pall. The peonies’ are rich ascorbic acid (1205.7 mg/100g ) tannins (15.9% 15.7% at beginning growth season. Concentrations flavonols, pectins, carotenoids Siberian peonies low is a promising species for further research on set levels because this stands...

ABEYSEKERA, R. M., NEWCOMB, W . , SILVESTER, W. B., and TORREY, J. G. 1990. A freeze-fracture electron microscopic study of Frankia in root nodules of Alnus incana grown at three oxygen tensions. Can. J. Microbiol. 36: 97-108. Nodulated plants of Alnus incana ssp. rugosa and ssp. incana were grown with the roots exposed to 5,21, and 40 kPa 02. The nodules were studied by freeze-fracture transmi...

ABSTRACT The establishment and growth of trees can be compromised by soil contamination which can reduce populations of key microbial symbionts. We describe the colonisation of grey alder (Alnus incana) by Frankia from 10 urban soils with varying degrees of organic and inorganic pollution. Principal components analysis (PCA) of soil chemical profiles showed a separation of remediated and unreme...

A buffer mixture consist in g of eq ua l molali t ies (m ) of potass ium dihydrogen phospha te and sodium succina te is proposed as a useful reference poin t in the study of acid-base equilibria, b ridging t he present gap be tween pH 5.5 a nd pH 6.8. The p(aH'YCI) at 25 °0 has been determined by elect.romo tive-fo rce measuremen ts for fi ve buffer solu tions in which m varied from 0.005 to 0....

BACKGROUND Preventing anaphylactic reactions as a result of natural rubber latex (NRL) proteins is an important concern in anaesthesia. The clinical relevance of a bacterial/viral filter (Pall BB25) in preventing sensitization to NRL by inhalation was tested in guinea pigs. METHODS Guinea pigs (n=8-10 in each group) were exposed to aerosolized NRL-contaminated cornstarch powder or to NRL in s...
