Developing countries are being encouraged to diversify their food exports by developing new products and adding more value to existing ones. Adding value to and diversifying food exports depends not only on changing production but also processing systems. The traditional Indian fruits are very rich in nutritional parameters and a variety of by-products can also be prepared from them. This paper describes the importance of some of Indian fruits like Bael, Phalsa, Wood apple and Custard apple. These fruit trees thrive well in stony, infertile and neglected lands and bear heavily without any input. Their bulk use in food industry will improve nutrition and provide variety. With little effort, they can be semi-processed locally for supply to food industry. This can provide employment opportunity to the unskilled but energetic youth. The medicinal values of these fruits have additional attraction and there is a tremendous scope for their further exploration.Keywords

The experiment was carried out to assessment of technological gap and performance of integrated diseases management (IDM) approach as a resistant variety, chemical seed dressing, soil and seed treatment as a bio-agents for antagonistic fungi on growth of cumin Fusarium oxysporum f. sp. cumini pathogens under field conditions. This experiment was conducted on farmer trials (OFT) villages like Bhusi, Patelo Ki Dhani and Baldo Ki Dhani in Pali distract four year (2014 to 2017). This area is major growing cumin cultivation and here major problem face farmer every year cumin wilt disease due to reduction of yields. During this experiment disease incidence of wilt was observed to be lowest (Disease Incidences 5.00%) when resistant variety GC-4, seed dressing Carbendazim @ 2.0g/ kg with Trichoderma harzianum@ 6g/ kg seed + application of 100 kg FYM enriched with T. harzianum @ 3.0 kg/ha for soil treatment before 15 days of sowing cumin. Maximum disease incidence (24.00%) was observed when traditional farmers practice (no seed treatment). The adoption of recommended improved crop production technology and plant protection measures was poor. The OFT was effective in changing attitude, skill and knowledge of IDM approach and yield increased upto 28.64 per cent more over the traditional farmers practices. Results indicates that IDM approach increased net income by Rs. 20,593/-ha over farmers practices.Keywords

Disequilibrium in the uranium series is a vital parameter to ascertain the state of equilibrium between uranium group (parent uranium) and its daughters, i.e. radium group of elements. The 238U isotope of uranium is the parent of 14 daughter isotopes forming the uranium series. The first five isotopes of 238U series, i.e. 238U, 234Th, 234Pa, 234U and 230Th form uranium group and the sixth to last isotopes of 238U series, i.e. 226Ra, 222Rn, 218Po, 214Pb, 214Bi, 214Po, 210Pb, 210Bi, 210Po and 206Pb form radium group. Isotopes in the uranium and radium group usually remain in equilibrium within the group, but disequilibrium commonly exists between the two groups. In an open system, the mobility of radium is significant due to radon gas produced as a daughter element in the radium series. Anomalies with excess radium are commonly found around springs and seepages, whereas uranium anomalies are usually found under reducing environments. A study was carried out in Devri area, Surajpur district, Chhattisgarh, India, to decipher the state of disequilibrium in the area by analysing the drill core samples (n = 4470) from 43 boreholes. This study has revealed a strong disequilibrium (65%) in favour of the parent uranium. This disequilibrium is due to cycles of dissolution and deposition of parent uranium; aided by the movement of groundwater and diverse geochemical behaviour of different radionuclides. In addition, loss of radon from the system might have also contributed to the disequilibrium in favour of the parent uranium. Linear regression coefficient between U3O8 (parent uranium) and RaEq.(U3O8) was calculated to be 0.82. Strong disequilibrium in favour of the parent uranium will enhance the uranium ore reserve in Devri area.Keywords

Chalcones and their derivatives have been an area of great interest in recent years. Numbers of research publications have been published and chalcones continue to show promising effect for new drug investigations. Chalcone is an advantageous species with medicinal importance as it is consisting of highly reactive ketoethylenic system –CO–CH=CH– which belongs to flavonoids. Chalcones (1, 3-Diphenyl-2-propen-1-one) consists of a three carbon α, β-unsaturated carbonyl system and two or more aromatic rings and acts as precursors for the biosynthesis of flavonoids in plants. However, synthesis in laboratory of broad range of chalcones has also been reported. In chalcone and its derivatives, a highly reactive α, β-unsaturated carbonyl system is the major reason for their pharmacological potencies. Chalcones and their derivatives are known to show a wide range of pharmacological potencies such as anti-inflammatory, antioxidant, antileishmanial, antifungal, anticancer, antibacterial, antiulcer, antiprotozoal, antitumor, antimalarial, antidiabetic, anthelmintic, insecticidal, antigout, antihistaminic, antiviral, antimycobacterial etc. Chalcones can be prepared by Claisen– Schmidt’s condensation, Aldol condensation, Heck’s reaction, Suzuki’s reaction, Ultrasound method of synthesis, Solvent free synthesis of chalcones, One pot synthesis, Sonogashira Isomerization coupling reaction etc. The purpose of the present review is to focus on the various methods of preparation of chalcones and derivatives and their anti-inflammatory and antioxidant potencies.

Chalcones and their derivatives have been an area of great interest for several researchers in recent years. Several number of research publications have been published and chalcones continue to show promising effect for novel drug investigations. Chalcone is an advantaged moiety with therapeutic importance as it comprises of receptive ketoethylenic moiety – CO–CH=CH– having a place with flavonoids. Chalcones (1, 3-Diphenyl-prop-2-en-1-one) consists of a three carbon α, β-unsaturated carbonyl system and two or more aromatic rings and acts as precursors for the biosynthesis of flavonoids in plants. The presence of a highly reactive α, β-unsaturated carbonyl system in chalcone and its derivatives is the justification for its pharmacological potencies. However, synthesis in laboratory of broad range of chalcones has also been reported. Chalcones show a wide range of pharmacological impacts like anthelmintic, antileishmanial, antifungal, antimalarial, antioxidant, antiviral, antibacterial, antiulcer, antimycobacterial, insecticidal, antigout, antihistaminic, antiprotozoal, insecticidal, anticancer, antidiabetic, anti-inflammatory, analgesic etc. Chalcones can be synthesized through Claisen–Schmidt's condensation, Heck's reaction, Aldol condensation reaction, Suzuki's reaction, from cinnamic acid, Sonogashira Isomerization Coupling reaction, Microwave assisted synthesis etc. The purpose of the present review is to centralize the various and widely employed methods of synthesis of chalcone and their various derivatives and their antimicrobial and antioxidant activities.Keywords
