Comprehensive identification and distribution pattern of 37 oxygenated heterocyclic compounds in commercially important citrus juices

The juice of pummelo (Citrus grandis Osbeck) was analyzed to determine its composition of flavonoids, polymethoxyflavones, coumarins and psoralens. The analyses were carried out by HPLC using columns packed with small diameter Fused-Core® C18 particles to achieve high resolution in short analysis time. In addition, the profile of the native carotenoids present in the juice was determined using a C30 column. Identification of flavonoids was achieved by MS with ESI in negative mode; the MS acquisition of oxygenated heterocyclic compounds was performed in positive APCI; carotenoids were detected with a PDA detector. Nineteen native carotenoids were determined in pummelo juice for the first time. The composition of this juice is also discussed in comparison with other Citrus juices, especially grapefruit.

Study of 10 km stretch of Gandak River in Uttar Pradesh revealed the ichthyofaunal diversity, assemblage structure, distribution pattern, threat status, ornamental and commercially important fishes. In all 54 fish species were recorded of many commercially important fishes. Among these species 45% belong to lower risk near threatened (LRnt), 26% vulnerable (VU), 11% lower risk least concern (LRlc), 11% not evaluated (NE) and 7% endangered (EN) category. Cyprinidae 33% were most important followed by Bagridae (11%), Channidae (9%), Tetradontidae (5%). DOI: http://dx.doi.org/10.3126/on.v11i1.8246 Our Nature Vol.11(1) 2013: 76-84

Attempts have been made to provides comprehensive information on the distribution pattern, nativity, classification, cultivation practices and uses of some important medicinal plants of India. The distribution pattern of the species plays an important role for prioritization of the species for cultivation and conservation. It has been noted that cultivation of medicinal plants within the distribution range has received greater success than the cultivation of species outside the distribution range. India has rich diversity in medicinal plants, which needs to be exploited judiciously without disturbing its ecological balance. Undoubtedly, resources need to be harnessed for economic development but simultaneously we have to be concerned about their regeneration, preservation and propagation, so what these are available to us for use on a sustainable basis.

This study aims to assess and evaluate the number of commercially important medicinal and aromatic plants (MAPs) found in the trade and explore their distribution pattern and conservation measures along the Himalayan elevation gradient of Nepal. The species data for this study are based on primary as well as secondary sources, where as elevation range data are based only on secondary sources. The number of MAPs species and number of conservation sites present in each 100 m elevation band is estimated by interpolation. The assessed numbers of commercial MAPs are assigned in to different life forms group to find the life form spectrum of commercial species. The number of MAPs species and conservation sites present in each 100 m elevation band are evaluated as a response variable where as elevation gradient is the predictor. The relationship between them is elucidated by scatter plot as well as generalised liner models. In this study, we have assessed 143 species as commercial MAPs. The variation of MAPs species is found related to elevation. The MAPs species richness increases with increasing the elevation up to 1000 m then decrease with further increasing the elevation thus unimodal type of pattern is observed. The maximum numbers of MAPs are found at 1000 m but maximum numbers of conservation sites are found above this elevation range. We did not find the significant pattern between conservation sites and MAPs species richness along the elevation gradient of the Himalayas. The conservation sites of Nepal are less concentrated where MAPs species diversity is rich.

Resolution Structure

The extended crystallographic defects introduced into some oxide catalysts under operating conditions may be a consequence and accommodation of the changes produced by the catalytic activity, rather than always being the origin of the reactivity. Operation without such defects has been established for the commercially important tellurium molybdate system. in addition it is clear that the point defect density and the electronic structure can both have a significant influence on the chemical properties and hence on the effectiveness (activity and selectivity) of the material as a catalyst. SEM/probe techniques more commonly applied to semiconductor materials, have been investigated to supplement the information obtained from in-situ environmental cell HVEM, ultra-high resolution structure imaging and more conventional AEM and EPMA chemical microanalysis.

Peroxisome induction can be expressed as an increase in peroxisome area (proliferation) or as an increase in peroxisomal fatty acid oxidation (activity). This study compares proliferation and activity as endpoints for hepatic peroxisome induction by perfluorodecanoic acid (PFDA). Fluorocarboxylic acids such as PFDA represent a class of compounds possessing commercially important surfactant properties. A single 50 mg/Kg ip. dose of PFDA produces a characteristic “wasting syndrome” in male F-344 rats. Symptoms include hypophagia, weight loss, hepatomegaly, and delayed lethality. Hepatic studies reveal changes similar to those seen with the hypolipidemic agent clofibrate. These include mitochondrial disruption, endoplasmic reticulum and peroxisome proliferation, and increased peroxisomal acyl-CoA oxidase activity.Male Fisher-344 rats received a single ip. dose of 2, 20, or 50mg/Kg PFDA dissolved in 1:1 propylene glycol/water and were sacrificed 8 days post-dose. All control rats received an equal volume of vehicle ip. Animals were provided food and water ad libitum, except pair-fed controls which received the same restrictive food intake consumed by their weight-paired dosed partners (50mg/Kg PFDA group) to simulate the hypophagia associated with PFDA.
