Arachis hypogaea (peanut or groundnut) is an economically important
crop. Thousands of peanut cultivars are grown in the world and many
studies have been carried out on them but, to the best of our
knowledge, no salient work has been done on Pakistani cultivar so
far. Here, we report the chemical composition of Pakistani cultivar
of Arachis hypogaea (peanut or groundnut) and its antiradical
activities by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical
scavenging and Phosphomolybdenim Complex (PC) method. This study
revealed that Pakistani cultivar exhibited an almost equal
antioxidant potential to that of Butylated hydroxytoluene, which
was obvious from the IC50 values.
Different analogues of Benzotriazoles and Benzimidazoles were
synthesized using different O-phenylene diammines as main reactant
and further analogues were prepared by substituting the benzene
ring and the heterocyclic ring of the above mentioned benzo-fused
moieties using reagents e.g. chloroacetic acid, halogenating agents
and hydrazine. Characterization of the synthesized compounds was
done by IR and NMR spectroscopic techniques. The synthesized
compounds were also screened for antimicrobial activity and were
found to have significant antifungal and antibacterial activity
against aspergillus niger and gram negative Bascillus specie.
Prunus dulcis is called Lawz in Arabic and Baadaam in Hindi,
Punjabi, Telugu, Gujarati, Turkish, Urdu, Persian and Kashmiri.
This Book describes the Classification, Nutritional value, Health
benefit, Chemical Composition, Habitat, History, Antioxidant
Activity and uses of Prunus dulcis. Also have data related to
Bitter and Sweet Prunus dulcis and their constituents, and describe
the bitterness factor in Prunus dulcis. Comparative study between
Pakistani and American Prunus dulcis were performed by comparing
the constituents percentage in both with the help of
1,1-Diphenyl-2-picrylhydrazyl radical scavenging activity, Total
Antioxidant Activity by Phosphomolybdenum Method and Gas
chromatography-mass spectrometry analysis.
Different kinds of methods such as Chemical Vapor Deposition (CVD),
Physical Vapor Deposition (PVD), Sol-Gel Deposition (SGD), Thermal
Spray Deposition (TSD), Jet Vapor Deposition (JVD), Triboadhesion
Deposition (TAD), & Electroless Deposition (ELD) were used for
the coating of metal oxides on glass substrates but it was found
that Electroless Deposition is the most effective and common method
for deposition of metal oxides on glass substrate due to its unique
characteristics. Effectiveness of deposition was studied by the
stability of metal oxides (Nickel & Copper Oxides) layer on
glass substrate. Stability was measured by comparing the duration
of crack formation at different temperatures and by changing the
composition of metallic & reducing agents solutions, on glass
substrate. Cracks formation was noted and measure with the help of
High Efficient Microscope. Metallic & Reducing agent solutions
properties were also noted by preparing them with different
methods. Reducing agents that commonly used in deposition are
hydrogen compounds, in which hydrogen atom is linked to phosphorus,
nitrogen, and carbon i.e, Sodium Hypophosphite,
Dimethylamine-borane, Hydrazine and Formaldehyde
