STUDIES ON PYTOCHEMICAL SCREENING ANDANTIBACTERIAL ACTIVITY FROM LEAF AND CALLUS EXTRACTS OF ORTHOSIPHON ARISTATUS (BLUME). MIQ.

Abstract
The aim of this study was to determine the phytochemical screening and antibacterial from leaf and callus extracts of Orthosiphon aristatus collected from different places in Tamil Nadu. Phytochemical screening involved the qualitative methods to detect the presence of terpenoids, flavonoids, phenols, tannins, steroids, quinones, saponins, cardiac glycosides and alkaloids. For the antibacterial activity different concentrations of ethanolic leaf and callus extracts were tested using the agar disc diffusion technique agaist Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. The phytochemical analysis of ethanolic leaf and callus extracts of Orthosiphon aristatus was shown the availability of significant secondary metabolites such as tannins, saponins, quinones, cardiac glycosides, phenols, flavonoids, terpenoids, steroids, and alkaloids. The antibacterial activity of ethanolic leaf extract of Orthosiphon aristatus shows maximum zone of inhibition in Bacillus subtilis followed by Escherichia coli. The ethanolic callus extract shows maximum zone of inhibition in Bacillus cereus followed by Pseudomonas aeruginosa. It was concluded that the powerful antibacterial effect was attributed in the ethanolic callus extract of Orthosiphon aristatus.

Antioxidant activity of Leaf extracts of Calophyllum inophyllum L. by DPPH method.

Abstract
Invitro antioxidant activity of Calopohyllum inophyllum L was studied by DPPH free radical scavenging assay, the tested extracts produced significant antioxidant activity. The maximum inhibition of DPPH free radical was exhibited by ethyl acetate extract followed by acetone extract, distilled water showed lowest inhibition at 1000mg concentration. The antioxidant activity of Calophyllum inophyllum helps to protect skin cells from damage by reactive oxygen species and other oxidative antagonists.

Synthesis of Silver Nanoparticles using Phyllanthus amarus and study of its antimicrobial properties against urinary tract pathogens.

Abstract
The integration of nanomaterial with biology is finding wide applicability in various areas of medical sciences. Recently, silver nanoparticles have gained attention because of their antimicrobial activity which offers the possibility of their use for medical purposes. Metallic nanoparticles can be obtained by physical, chemical or biological methods. But silver nanoparticles synthesized by chemical reduction methods are found to be toxic, flammable and not at all eco-friendly. Therefore in the present study, an attempt was made to formulate a cost effective and environment friendly technique for green synthesis of silver nanoparticles. The silver nanoparticles were synthesized using extract of Phyllanthus amarus with AgNo3 solution . Their antibacterial activity was studied using agarwell diffusion method on isolates viz., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis, Enterobacter obtained from patients suffering from urinary tract infection. The antibacterial efficacy of silver nanoparticles of Phyllanthus amarus was found to be superior to that of hot or cold extracts of Phyllanthus amarus silver nanoparticles were characterized by UV-Vis spectroscopy and scanning electron microscopy (for particles size analysis). This work demonstrates the possible use of biologically synthesized silver nanoparticles to treat urinary tract infections.

IN VITRO ANTIOXIDANT ACTIVITY, TOTAL PHENOL AND TOTAL FLAVONOID CONTENT OF Orthosiphon aristatus (Blume). Miq.

Abstract
The aim of this was to examine the antioxidant activity, total phenol and total flavonoid content of the leaf of Orthosiphon aristatus collected from three distant regions of Tamil Nadu namely Azhizar, Trichy, Chengalpattu. These were examined using extracts of aqueous, ethanol, acetone, chloroform and petroleum ether. The leaf extracts were evaluated for antioxidant activities by DPPH (1,1 – diphenyl -2- picryl-hydrazyl) radical scavenging assay. Among three accessions with different solvents used, maximum antioxidant activity was found in ethanolic leaf extract 85.2% from cuddalor followed by others. Total phenol and flavonoid content was quantitatively estimated, the ethanolic leaf extract of Orthosiphon aristatus was found maximum in Azhiyar accessions (17.13 mg Gallic Acid Equivalents (GAE)/g and 9.30 mg Quercetin Equivalents (QE) /g). The powerful antioxidant activity is attributed to the greater amount of total phenol and flavonoid compound in the ethanolic leaf extract ofOrthosiphon aristatus

EFFECT OF ORGANIC AND INORGANIC FARTILIZERS ON GERMINATION PERCENTAGE AND SEEDLING CHARACTERS OF SUNFLOWER

Abstract
The present study examined the effects of organic and inorganic fertilizers on germination percentage, shoot length and root length, whole plant fresh and dry weight of sunflower plants. There are four sources of organic fertilizer: Agricultural waste compost, market waste compost, paper waste compost and their combined treatment. While, N,P,K and their combination treatments were used as the source of inorganic fertilizers. The results observed that, the combined treatment of organic fertilizer shows highest percent of germination followed by N+P+K, when compared to individual treatments and control. The treatment with organic fertilizers is found to be more effective than the inorganic fertilizer in sunflower plant.

IMPACT OF HEAVY METAL, CHROMIUM ON GLYCOGEN CONTENTS IN GILL, LIVER AND KIDNEY OF FRESHWATER FISH, Channa striatus (BLOCH)

Abstract
Fish is generally appreciated as one of the healthiest and cheapest source of protein and it has amino acid compositions that are higher in cysteine than most other sources of protein. Heavy metals are natural trace components of the aquatic environment but their levels have increased due to industrial wastes, geochemical structure, agricultural and mining activities. All these sources of pollution affect the physiochemical characteristics of the water, sediment and biological components and subsequently affect the quality and quantity of fish stocks. The chromium is present in the tannery effluent and is known to cause various ill effects. Such health hazards are dependent on the oxidation state of chromium. Its hexavalent form is more toxic than the trivalent form. The aim of the present study was to assess the glycogen contents in gill, liver and kidney of Channa striatus was exposed to sublethal concentrations of chromium for the period of 10, 20 and 30 days. The fish exposed to chromium showed a decreased the glycogen contents for 10, 20 and 30 days in gill, liver and kidney. The objective of the present investigation was to observe the effect of chromium on glycogen contents in the gill, liver and kidney of freshwater fish, Channa striatus.

DEVELOPMENT OF VITAL GENERATION THROUGH QUEEN REARING TECHNIQUE IN APIS CERANA INDICA

Abstract
Domestication of honey bees for collecting honey, bee wax and pollen is called bee keeping. There are about 20,000 species of honey bees in the world. The Indian honey bee, Apis cerana indica Fab.is used in South India for commercial beekeeping and honey production. Eventhough the industry had developed tremendously; better performing colonies/strains with desirable traits are required for increased productivity and sustainable apiculture in South India. Concurrently, most of the colonies of A. cerana indica are not economically viable, Selective breeding is the best solution for stock improvement. Better genetic traits can be transferred and the productivity can be increased through selective breeding, so as to evolve best performing Indian bee colonies, Hence the present study was undertaken with a view to identify Indian bee A. cerana indica colonies with viable characters and develop a better perfoñning strain with desirable traits for improving the stock through selective breeding for sustainable apiculture in the State. The bee colonies with desirable characters were selected for evolving colonies with economically important traits. Production of potential queens through artificial queen rearing technique could be standardized in the study and further exploited for developing better performing colonies through selective breeding. The selectively bred colonies developed in the study could be subjected to extensive studies for further bee stock improvement.
