INVENTORIZATION, CONSERVATION AND CHARACTERISATION OF BIO-RESOURCES


Medicinal and aromatic plants:
3.1 The volume of trade in herbal products is quite large. A recent survey estimates the total turn over of Ayurvedic and other herbal products to be around Rs.23 billion per year.
3.2 Presently only a few medicinal plants are cultivated in the State. Furthermore, rapid urbanization of the State brings a great threat i.e. the shrinkage of forest lands. Therefore, a step-wise program will be carried out to conserve medicinal and aromatic plants (especially ex-situ) and also to genetically characterize these plants. Gene banks would be established for endangered and endemic taxa, those employed in tribal and folk medicine, and others that are commercially exploited.






3.3 The tribals in Orissa use many crude herbal products for health care The biosphere reserve of "Similipal" and forests like "Gandhamardhan" and "Harisankar" house a large number of medicinal plants. The herbal products derived out of these plants need to be validated scientifically before commercialisation in the form of new therapeutic formulations.
3.4 Studies on bio-prospecting for new genes and gene products would also be encouraged.
Mangrove species :
3.5 The micro-flora (bacteria) of mangrove eco-systems comprises several phosphate metabolizing species. Their identification and characterization will be carried out in detail.
3.6 The specific physiological and biochemical characteristics of salt loving plants can be a resource for genetic manipulation. These species can be explored at the genetic and molecular levels for their salt tolerance properties.
Horse shoe crab:
3.7 The horse shoe crab, Limulus polyphemus is available in U.S.A. only. Similar crabs viz., Carcinoscorpius rotundicauda, Tachypleus tridentatus and T. gigas are also available in Orissa coast. The haemolymph of this crab is used for testing the presence of bacterial endotoxin (pyrogen testing) of pharmaceutical products. Therefore, the haemolymph of the locally available crab can be used for development of indigenous pyrogen testing kits in India. The current regulations of CPCSA do not allow the use of rabbits for pyrogen testing and hence only imported kits are currently in use in India for pyrogen testing. This is one area, which can be taken up for immediate benefit.
