Vyas Seema, Jain Deeksha, Anand Priya, Mali M.C. and Bhojak N,IJGHC, June 2018 – August 2018; Sec. A; Vol.7, No.3, 500-504.DOI: 10.24214/IJGHC/GC/7/3/50004

The present paper describes potential application of four different formulations prepared from the leaves of Croton bonplandianum on female mosquitoes of Anopheles stephensi. Net and bottled technique was developed for testing of antimosquito activity of different paste obtained from the leaves of Croton bonplandianum. Four herbal formulations were prepared using different pastes obtained from leaves of Croton bonplandianum. In typical preparation of herbal formulation 1 to 5% weight by volume ratio of leaf paste waste taken in the same material in which paste was prepared and it was standardized and or optimized. Number of mosquito dead were counted after every half an hour. At first half 5 hour and at ten hour, each experiment was repeated twice. It has been found that maximum repellent activity is observed with til oil formulation for pastes obtained from leaves of Croton bonplandianum

Synthesis, characterization and antifungal activity of p-CH3 benzyl and p-Cl benzyl Cinnamo Hydroxamic acids

Anita Patel, Surendra K. Rajput, Kishor N. Bapat and Deepak Sinha,IJGHC, June 2018 – August 2018; Sec. A; Vol.7, No.3, 489-499.,DOI: 10.24214/IJGHC/GC/7/3/48999

Synthesis of p-CH3 benzyl and p-Cl benzyl cinnamohydroxamic acids were prepared by the coupling reaction between p-methyl benzyl hydroxyl amine, and p-Cl benzyl hydroxyl amine with cinnamoyl chloride. Their characterization was done by the standard spectroscopic method 1HNMR, IR spectroscopic study and Elemental analysis. The promising biology and medicinal application potential of p-methyl benzyl and p-Cl benzyl cinnamohydroxamic acids prompted us to investigate antifungal activity of p-methyl benzyl and p-Cl benzyl cinnamohydroxamic acids against two fungal strains Penicilliumgriseofulvum, Fusariumsolani, by the paper disc agar plate method. The fungal cell growth zone of inhibition by these compounds p-CH3BCHA and p-ClBCHA are found for Penicilliumgriseofulvumare 15.68 mm, 17.00 mm and for Fusariumsolani are 18.90 mm, 16.23 mm, at higher concentration 1000 ppm respectively. Detailed antifungal testing shown that these compounds are good cell growth of inhibition by the study of antifungal activities against two fungal strains i.e. Penicilliumgriseofulvum and Fusariumsolani.

Determination of minimum effective concentration of honey that optimizes larval growth and silk production in the silkworm, Bombyx mori.

R. Madhavi, S. Arivoli and S. Siva Prasad,IJGHC, June 2018 – August 2018; Sec. A; Vol.7, No.3, 477-488,DOI: 10.24214/IJGHC/GC/7/3/47788

The study deals with the determination of minimum effective concentration (MEC) of honey that optimally reinforces Bombyx mori larval growth and silk production. The methodology is based on impact analysis of honey-enriched mulberry diet on larval growth parameters like body weight (BW), body length (BL) and body perimeter (BPM) and silk productivity parameters like gland-body ratio (GBR) and silk gland proteins (SGP)at five different concentrations (5%, 4%, 3%, 2%,1%) of honey. The instar-wise and day-wise growth trends were analyzed respectively by overall growth rates (OGRs) and compound periodical growth rates (CPGRs). Of all, 2% honey elicited maximal response in all parameters. Compared to respective zero dose controls, OGR of BW, BL and BPM grew additionally by 33.0, 10.0 and 11.0 percentile points in third instar, 20.0, 9.3 and 4.0 percentile points in fourth instar and 8.3, 5.0 and 9.0 percentile points in fifth instar. Similarly, CPGR of BW, BL and BPM grew additionally by 19.3,3.5 and 3.9 percentile points in third instar, 3.6, 2.7 and 1.2 percentile points in fourth instar and 0.46, 0.55 and 0.69 percentile points in fifth instar. Likewise, OGR of GBR and SGP were boosted by 28.0 and 122 percentile points and CPGR by 1.4 and 6.4 percentile points. Hence, 2% honey in distilled water is recommended as the potential MEC that positively modulates larval growth and sericultural productivity. The study further indicates that maximal sericultural output could be reaped by feeding silkworm larvae with honey-enriched mulberry leaf from third instar onwards.

A Novel Assent for Synthesis of Pyrazoline Derivatives by adopting Graphene Oxide Nanosheets as carbocatalyst at reflux condition

D.R. Munde R. P. Kagne, V.G. Kalalawe, S.J. Manegawade S.N. Niwadange,IJGHC,DOI: 10.24214/IJGHC/GC/7/3/46976. June 2018 – August 2018; Sec. A; Vol.7, No.3, 469-476.,

A novel route was amended for synthesis of 1,3,5- trisustituted pyrazoline derivatives from substituted chalcones and phenyl hydrazine or hydrazine hydrate in ethanol by using Graphene oxide nanosheets as a heterogenous carbocatalyst at reflux condition.The reaction protocol gave 1,3,5-trisubstituted-2-pyrazolines in good yields via a one-pot addition cyclocondensation between aryl hydrazines and chalcones. The catalyst may be reused without showing much loss in the catalytic activity.The synthesized compounds were confirmed by their spectral data analysis

Current research for targeting fluorescent “turn-on” detection of palladium species in various approaches

Koushik Dhara,IJGHC, June 2018 – August 2018; Sec. A; Vol.7, No.3, 462-468,DOI: 10.24214/IJGHC/GC/7/3/46268

Palladium, a transition metal, is used in various fields, such as automobile and electronics manufacture, medicine, jewelry making, drug synthesis and in synthesis of organic chemicals for research interest. Palladium is used as a key catalyst in the Kumada, Heck, Suzuki, Sonogashira, and Buchwald–Hartwig reactions in the field of organic synthesis. Thus, the wide range of applications make the environmental contamination with palladium species. Also the human body system is being contaminated with the palladium species through the consumption of palladium impurity during the uptake of drugs. Recent studies have showed that even a small dose of palladium ions can cause an allergic reaction inBody system. Therefore, an efficient method must be developed to detect palladium ions in the environment and in biological systems too. This review deals with the recent reports of various fluorescent probes that showed a “turn-on” response due to palladium ions and their mechanistic way for selective detection. This will help to understand the fascinating role of palladium ions in further.
