Dykes intrusives of the Gingee area, Villupuram district, Tamilnadu, South India are chiefly composed of the clusters of mafic dykes found emplaced crisscrossing the entire district. They represent a significant phase of basic magmatism in the Southern Granlitic Terrain (SGT), which forms the Precambrian crust of the Southern Indian shield. Precambrian crust of the Earth constitutes nine cratons, namely regions in Asia and Indian subcontinent, Europe, Greenland, North America, South America, Africa, Australia and Antarctica. In this study reveals on dolerites in Gingee area based on petrography and geochemical analyzes. Petrography of the samples relects on ophitic to sub ophitic texture. IUGS classification shows basaltic nature.

As a group amphibians are the vertebrates most affected by anthropic activity water temperature, particularly by agriculture & non agriculture pond, grass land. The rapid advance of the agricultural frontier makes it important to identify the role of agro ecosystems as habitat supply for amphibians. Climate and agriculture are interrelated processes and both of which take place on a global scale. The relationship is four sided. Climate will affect agriculture through rainfall, temperature, activity and other conditions. Since some plants need specific conditions to grow. Nagapattinam district has been choose for the study and it has plain topography. The study area has tropical climate and it is suitable for agriculture. The rainfall is received during the North East monsoon and low rainfall from South west monsoon. The district is predominantly an agricultural region which lies in the Eastern part of Cauvery delta and it is called the Rice Bowl of Tamil Nadu. The present study area lies between. The Nagapattinam district lies on the east coast of the south Cuddalore district and another part of the Nagapattinam district lies to the south of Karaikkal and Tiruvarur districts. It is bordered by the Bay of Bengal. The district lies between 10°25’ and 11°40’ North Longitude and 76°49’ and 80° The climate and its impact on agriculture is analyzed based on the data collected and accordingly the study area and relevant maps for this study were prepared using Geographical information system.

Antioxidant plays an important role in inhibiting and scavenging free radicals, thus, providing protection to human against infection and degenerative diseases. Now the modern research is directed towards Natural antioxidants from the herbal plants due to safe therapeutic values. In the present investigation the Antioxidant activity of extracts from medicinal plants such as Acalypha indica, Azadirachta indica, Euphorbia hirta, Fiscus religiosa, Pongamia pinnata and Thespesia populnea are evaluated for its free radical scavenging activity by adopting various invitro methods. The extracts were investigated for the antioxidant activity using reducing capacity, Hydroxyl group reducing activity and DPPH methods and the phytochemicals contents such as alkaloids,carbohydrate, flavonoids, glycosides, phenolic contents,proteins, reducing sugers,sapinins, steroids,tannins, and terbinoids, were analyzed qualitaively.

The studies on the diversity of fruit degradating soil fungi from Pudukkottai district. To assess the density of fungal flora. To isolate and identify the fungi from the soil with fruit degrading materials along some physic-chemical parameters like temperature, pH, electrical conductivity, organic carbon nitrogen, phosphours, potassium magnesium, sodium, zinc, copper of fruit degradating soil sample during the year 2015. It has been estimated that 2.3 million fungal species are present in natural eco system, but only 5-10 percent have been formally. For the important functional role of fungi in soil samples include Alternaria alternata, Aspergillus awamori, A.candidus, A.flavus, A.fumigatus, A.terreus, A.luchuensis, A.sydowii, Cunninghamella sp, Curvularia lunata, Fusarium solani, Fusarium sp, F. oxysporum, Gliocladium virens, Penicillium citrinum, P. griseofulvum, P. longibracteatum, P. lanosum, Rhizopus stolonifer, Rhizopus sp.

The invitro anti-inflammatory activity of C.inophyllum L. Leaf was evaluated by HRBC method. The ethylacetate extract showed significant anti-inflammatory activity at 1000Mg/mL concentrations. The activity was dose dependent. The ethyl acetate extract in 1000mg/ml concentration was considered statistically significant compared to the standard drug.

Qualitative analysis of leaf extract of Calophyllum inophyllum revealed that the presence of alkaloids, amino acids, carbohydrates, fats, flavonoids, glycosides, phenols, protein, sterols, tannins and triterpenoids. Carbohydrates, flavonoids, phenols and protein were present in the tested three extracts such as acetone, distilled water and ethyl acetate extracts while alkaloids, amino acids and fats were detected only in ethyl acetate extract.

Quantitative phytochemical analysis of leaf extracts of calophyllum inophyllum L. revealed that carbohydrate content in distilled water extract was higher than that of ethyl acetate and acetone extracts. The ethyl acetate extract of the plant recorded highest percent of total protein, flavonoid, phenol and vitamin C content. Vitamin E content extract was higher in acetone extract compared with that of ethyl acetate and distilled water extract.

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.
