Objective: Evaluation of tyrosinase inhibitory activity of spices. Materials and methods: Ten different spices considered as usual commodity in Indian food habits was screened for their inhibitory activity against tyrosinase. The mushroom tyrosinase inhibitory activity was determined by dopachrome method using L-DOPA as the substrate. Results: Amongst the spices tested four spices viz. Turmeric (Curcuma longa ), cumin (Cuminum cyminum), black pepper (Piper nigrum), pipal (Ficus religiosa) showed the specific inhibitory activity against tryrosinase above 50% and out of them turmeric showed maximum inhibition which can be further explored for the characterization of the phytoconstituents. Other spices showed potential inhibition of tyrosinase activity. Conclusion: This finding could lead to the design and discovery of new tyrosinase inhibitors from Indian spices.Keywords

Objectives: To examine ethno-medicobotany of Toda tribe in the Nilgiri hills of South India. Materials and methods: Ethnobotanical field survey and personal discussion methods have been made use of in the collection of data. Results and discussion: A list of 32 botanicals (30 dicots and 2 monocots) plants belonging to 31 genera, 29 families and 32 species are employed for therapeutic purposes by the Toda tribe of Nilgiri hills, South India. The Parmelia caperata a type of moss paste is applied to wounds caused by animal bites for healing. In analyzing ethno-medicobotanical information, we present here data on various ethnomedicinal claims and method of applications to treat a host of ailments are underlined here. A short description of plants, their habitat, family and local names are also summarized here.Keywords

The artificial neural network (ANN) technique is at present most efficient and modern tool for parameter estimation and inversion of geophysical data. This paper deals with the application of ANN technique for the inversion of vertical electrical resistivity sounding(VES) data obtained from the NNW SSE part of Barmer district, Rajasthan. The efficiency of ANN technique is tested first on synthetic resistivity data generated from the numerical model and then trained on the actual VES field data. The analyses predict sediment thickness of the order of 172 m at Rawtra (S 15, and indicate that there is possibility of fresh aquifers at all sounding locations along the profile except at Sonadi (S 1). These results match with the depth-Resistivity structure obtained by the conventional method. However, the high accuracy and faster ANN imaging system seems to have highly correlated with that of conventional method for mapping the complex subsurface resistivity structures with less ambiguity. These finding also correlate remarkably well with known drilling results and geologic boundaries.Keywords
