An Overview of Reactivity and Biological Activity of Hypercoordinated Organosilicon Compounds – A Green Approach

Dr. Priya Duggal

The chemistry of silicon is largely that of four coordinated compounds but many stable compounds containing five and six coordinated silicon are known. Hypercoordinated silicon compounds attract interest from both the structural and reactivity point of view. The isolation of such compounds allows detailed insight into mechanistic pathways of nucleophilic substitution at silicon. On the other hand compounds based on such synthons exhibit interesting properties as electronic materials.  Apart from the rich chemistry of these penta and/or hexacoordinate silicon compounds, it has been found that these species are relatively cheap, have low toxicity and are environmental friendly reagents. Therefore much of the research efforts, recently have been directed towards their synthesis, reactivity, structural investigations and biological activity of such compounds. The present paper deals with the overview of reactivity and biological activity of some penta and hexa-coordinated silicon compounds.

Petrit Rama; Bari Hodaj;Thoma Nasto and Hekuran Vrapi,DOI: 10.24214/IJGHC/GC/8/1 /03742

Naturally, the hazelnut tree grows in multiple stems. However, for hazelnut production, the cultivation of hazel tree is making in form of a bush and in form of a tree with one trunk. The form of a bush is suitable for smaller, family orchards in which a large number of complex technical activities are made by hand. The form of cultivation with one trunk enables application of mechanization and modern agro technical interventions including mechanization of harvesting and is therefore mainly applied on plantations of agriculturally developed countries. We studied the influence of those two forms cultivation on fruit production in five years old hazelnut tree cv.Visoka. We found that the total of TCSA (trunk cross-sectional area) of the three trunks of the bush was markedly greater than the TCSA of the single trunk of the tree that was cultivated with a trunk, respectively 47.916cm2 and 37.23 cm2. Fruit yield was positively related to TCSA (trunk cross-sectional area), respectively 1456.66 gr./tree and 1210 gr./ tree. In both cases the yield efficiency, (kg yield per tree) / (cm2 TCSA) was almost equal (30.394gr/cm2 and 32.448gr/cm2.

Aishwarya. A. Andhare, Ravindra S. Shinde, A. J. Deshmukh,DOI: 10.24214/IJGHC/GC/8/1 /05560.

The present study was carried out to use banana peels (Musa sapientum), duckweed (Lamna minor) and egg shell as an organic fertilizer. Banana peels and egg shells are any how wasted and can be a great source of biodegradable source of garbage while duckweed is contaminated aquatic plant, causes reduction in aquatic life.  In split of that, these ingredients are having high nutritional value. The research was conducted to prepare a cheap organic fertilizer using these three ingredients. Interestingly, organic fertilizer prepared from these ingredients gave excellent results in wheat crop. Wheat crop supplemented with the organic fertilizer in a pot grow very rapidly and there is increment in agronomic parameters viz., seedling emergence, emergence of two leaf stage, tillering, advanced tillering, jointing, flag leaf emergence, flag leaf fully emergence, boot stage and head emergence as compared to wheat crop non supplemented with the organic fertilizer. Moreover to this a significant difference in soil pH was also observed. Field collected soil was observed to have 5.7 pH whereas the soil added with the organic fertilizer has 6.9 pH and which we generally consider as normal pH. Thus these positive results of earliness of wheat crop and change in soil acidic pH to normal pH is only possible as these ingredient base fertilizer might have contains increased concentration of essential nutrients needed for plant growth and development as compared to regular field soil.

C.I. Nosiri, U.O. Arunsi, A.C. Ngwogu, J. Idume and O.C. Atasie,DOI: 10.24214/IJGHC/GC/8/1 /08392.

The gastroprotective effect of Annona muricata (Linn.) seed extract on aspirin induced ulcer model in wistar rats was evaluated using standard analytical methods. A total of twenty-five (25) Wistar rats used in the study was divided into 5 groups of 5 rats each: 1, Normal control (received 0.2ml distilled water); 2,Negative control (received 400mg/kg Aspirin); 3, Positive controla (pretreated with omeprazole 20mg/kg);4, positive controlb(pretreated with A. muricataseed extract 200mg/kg); and 5,positive controlc (pretreated withA. muricataseed extract400mg/kg extract).The result divulged that the administration of Aspirin led to significant increase (p<0.05) in ulcer score, ulcer index, gastric volume, total acidity and pepsin activity with means and standard deviations of 14.92 0.09; 10.10 0.17, 7.12 0.23mL; 12.14 0.21mEq/L; and 98.82 0.17mEq/L respectively. These ulcerogenic indices were lowered significantly (p<0.05) in groups pretreated with omeprazole and ethanolic seed extract of A. muricata. Furthermore, Omeprazole offered higher percentage gastroprotection than A. muricata seed extract. The degree of gastroprotection is in the order: A. muricata (200mg/kg)<A. muricata (400mg/kg)<Omeprazole (20mg/kg). The findings of the present study demonstrated that ethanolic seed extract of A.muricata manifested comparable gastroprotection effect against aspirin-induced ulceration vis-à-vis the reference drug. Omeprazole and the different doses of the extracts in this study may have suppressed gastric acid secretion via inhibition of H+/K+ ATPase or enhanced prostaglandin synthesis.

Raghvendu Pathak,DOI: 10.24214/IJGHC/GC/8/1 /09398

Environmental pollution, viz., air, water, soil, etc., is generally caused by natural phenomena as well as due to anthropogenic activities. Natural phenomena triggering environmental pollution are earthquakes, tsunami, landslides, floods, solar storms and volcanic eruptions upon which there is no human control. These biogenic activities may or may not be caused by El Nino or Al Nina effects. However, thoseprecipitated by differentbut direct human activities areglobal warming (due to greenhouse effect),ozone-layer depletion, eutrophication or hypertrophication of water bodies, release of toxic chemicals, fertilizers, plastic and polymersin soil, air and aquatic environment and setting free of radio-active materialsinto the same. Over the years, our environment has been damaged almost to beyond repair. The effect of environmental pollution is quite visible in climate change in the form of unusual heat-wave conditions and unseasonal rains and snows experienced throughout the world including India.Now it’s a high time to do something fruitful so that some of the environmental pollutionscan be mitigated to some extent, until it becomes too late. In this endeavor, titanium dioxide (TiO2) which is a non – toxic versatile green chemical can play a vital role. The present paper deals with attenuating ability of TiO2, a green photocatalyst, in removing some of the hazardous pollutants from the environment.

Isolation and characterization of storage seed deteriorating fungi and their effect on groundnut seeds

Rishabh Chitranshi and Naveen Kumar Arora ,DOI: 10.24214/IJGHC/GC/8/1 /12835

Groundnut (Arachis hypogaea L.) is an important oilseed crop in India. It has a good contribution to Indian economy. Oil seeds are highly susceptible for fungal infections under storage condition as they have ample amount of nutrients in them. Different fungal species of Aspergillus were dominant in coursing infections in groundnut. Aspergillus species cause various deteriorative alterations by physical and chemical means in groundnut seeds. Storage fungi cause chronic infection in seeds due to favorable environmental conditions such as moisture, relative humidity and temperature. In current study, fungal pathogens were isolated from Groundnut seeds. Groundnut seeds were singled out from warehouse located in Farrukhabad, Uttar Pradesh, India. Two dominant fungal pathogens RF-02 and RF-07 which cause major destruction in storage groundnut seeds were selected for further analysis at genus and species level by using 18S rRNA sequencing technique. Fungal strains dominantly covered up about 90 percent of groundnut seeds. After 18s rRNA, sequencing RF-02 and RF-07 strains were identified as Aspergillus flavus and Aspergillus niger. These identified sequences were submitted in NCBI and got the accession numbers KY933394 and KY357318 respectively
