For development in the industrial field, automobile sectors and other advance fields metal production is of primarily important. This is the cause of competing the developing countries among themselves for the production of different kind of metals by using different modern technologies economically and easily. Steel industries is now a growing industrial sector all over the world. India occupy second position in metal production after china. The generation of huge amount of various kinds of solid waste from different integrated steel industries of the world and also in India is a challenge for scientist and researchers. Hence its disposal, eco-utilization and management is of much essential to save our environment from extra pollution load. Different kinds of solid waste such as BF slag, granulated BF slag, SMS slag, BF sludge, Sinter sludge, Fly ash along with unused raw materials are generated from integrated steel industries, which not only increases the pollution load of the environment at that area but also affect the socioeconomic factors of the local people and sometimes destroys the agricultural land nearby it and disturbs the ecosystem. In this paper major emphasis is given to reduce the pollution load by utilizing proper technique of waste disposal, management and eco-utilization.

Two ultrasound-assisted delignification processes of the apompo pulp (Pachira aquatica) were compared. Apompo pulp is a lignocellulosic material with potential for obtaining bioethanol, the percentage of lignin found in the pulp was 29.77%. The alkaline ultrasound-assisted delignification with NaOH at 60 ° C presented the best lignin removal with 67.02%, compared to the process of acid ultrasound-assisted delignification yielding 50.56% removal of lignin. The pulp of the apompo without delignification process has a 4.84% cellulose, this percentage was increased in the delignified pulp by sonication with NaOH at 60 ° C obtaining 66.89% of cellulose.

Kshitij Agarwal and Anurekha Jain,DOI: 10.24214/IJGHC/GC/8/2 /33340

Solena amplexicaulis, commonly called as the creeping cucumber, belongs to the family Cucurbitaceae. Traditional it is used as astringent, appetizer, carminative, cardiotonic, digestive, diuretic, expectorant, invigorating, purgative and stimulant. Plant also having antioxidant antidiabetic and antibacterial action. The leaves showed potent anti-inflammatory activity. The present study was carried out to establish the pharmacognostical parameters of the plant. The macroscopical and microscopical characters were studied. The transverse section (T.S.) of leaf indicated the presence and arrangement of various cells layers mainly epidermis, parenchyma, collenchyma, vascular bundles and other cells. Powder microscopy was performed and non-lignified fiber and unicellular trichome, prismatic crystal, annular xylem vessel, tracheid and spiral and annular vessel were identified. The histochemical color reaction of T.S with different chemical reagents revealed the presence of carbohydrate, flavonoids, sterols, phenolic & tannins compounds. Fluorescence analysis of powder treated with different chemical reagents was studied under ordinary light, long UV lights. The microscopical standardization parameters always be helpful to maintain purity, quality and for sample identification.

Investigated of Chlorophyll for Analysis by Spectroscopic Technique

K.Dhivyabharathi, A.Kalpana, S.Ramya1, C.Kavitha,DOI: 10.24214/IJGHC/GC/8/2 /34153

The green plants are the reserves of chlorophyll that not only enable the plants to prepare their food but also benefit the humans and herbivores when ingested. It is an excellent antioxidant and has quite a lot of   bioactivity. Although many methods are known for estimation of chlorophyll content, the spectrophotometric method are, easy and apt method. Chlorophyll content would definitely vary from plant to plant depending on exposure to sunlight, preservation, heating etc. Therefore in the present work we have chosen to address the following issues for the chosen two plants using viz., Mentha piperitia   and Murraya koenigii. A monitor of the chlorophyll content by two methods both are identified with UV-Visible spectrophotometer           and analysized  of variation of chlorophyll over time (by Method 1) and also determined their compensation point. The effect of heat on chlorophyll content by exposing the sample to 5 mins (mild) to 20 mins (strong) and determining the chlorophyll content by Method 2.The evaluated of this above two process by using UV- Visible spectrum of sample between 300-700 nm.

Vis-a-vis the many environmental and social problems related to the urbanisation of natural space, the diagnosis and the environmental evaluation nowadays arouse more and more interest for a livable and sustainable environment. It is in this context that this study is which has as general objective to determine the floristic composition and the structural diversity of the woody species of the town of Bouaflé. With this intention, inventories of arborescent species were carried out inside the plots of 20 m x 20 m (400 m²) coupled to itinerant inventories inside the various types of installation were carried out. The investigations made it possible to identify seven (07) types of town-planning inside whose 99 arborescent species divided into 75 generea and 33 families were listed. Woody in cash richest types of town-planning are the social and educational establishments while the public garden with 3 species and sports equipment with 2 species represent the poorest mediums woody in cash. The cemeteries with a density of 236 trees/ha and a basal area estimated at 61.16 m²/ha represent the mediums floristically densest biotope.

Synthesis, Spectral characterization and biological activity of Copper complexes with 6-Nitro-benzothiazole-2-yl-hydrazones derivatives">

S.S.Kolate , G.P.Waghulde, C.J. Patil, C.H Sarode and V.S. Waghulde;DOI: 10.24214/IJGHC/GC/8/2 /36776.

A series of Cu(II) complexes with 6-Nitro-benzothiazole-2-yl-hydrazone derivatives have been synthesized and characterized by elemental analyses, FT-IR, UV–Vis, mass spectra and magnetic moment. The results of elemental analyses data and Job’s continuous variation method spectrophotometrically indicated the stoichiometry of the complexes as 1:1[M:L] ratio. The FTIR spectral data suggest that the ligand behaves as tridentate moiety with NNO donor atoms around to the metal ion. The UV–Vis spectra and magnetic moment data suggested an tetrahedral geometry in all complexes whereas Cu(BHHM)(Cl)(H2O) complex show trigonal bipyramidal geometry. The synthesized complexes were screened for antimicrobial activities against two Gram-positive bacteria (Bacillus subtilis and Streptomyces griseus) two Gram-negative bacteria (Salmonella typhi and Pseudomonas aeruginosa) and two funguses (Candida tropicalis and Kluyveromyces marxianus). The antioxidant activities of these complexes were determined by hydrogen peroxide (H2O2) scavenging activity.">

D. N. Mokat, D. G. Madavi and Y. C. Suryawanshi ;DOI: 10.24214/IJGHC/GC/8/2 /37785.

Tree borne oil seeds (TBO’s) is one of the important group of Non Timber Forest Products (NTFP’s) having multifarious usage and industrial applications. Maharashtra state is a treasury for genetic and species diversity of TBO’s. In the present investigation morphophysiological studies of 9 TBO’s viz. Aphanamixis polystachya (Wall.) R. Parker, Holoptelea integrifolia Planch, Madhuca longifolia var. latifolia (Roxb.) A. Chev, Mesua ferrea L., Mimusops elengi L., Moringa oleifera Lam., Pongamia pinnata (L.) Pierre, Putranjiva roxburghii Wall, Ricinus communis L. collected from Western Ghats of Maharashtra were studied. Out of the studied TBO’s maximum oil content was recorded in M. ferrea (78.78%) followed by H. integrifolia (54.77%), and lowest in M. elengi (19.84%). Maximum 100 seed weight was observed in M. ferrea (336.8 gm) followed by M. longifolia (332.67 gm) and lowest in H. integrifolia (1.98gm). High fatty acids variation found in P. pinnata and M. oleifera. Oleic acid is found to be a dominant fatty acid in higher concentration in the seeds of studied TBO’s. This investigation also provides information about the oil quality and fatty acid composition. Its industrial applications and bioprospecting is to accessed very much for future use.
