Increasing demand of these medicinal plant species for pharmaceutical industries, ornamental purpose and its use in traditional culture may endanger them and this may even lead to their extinction forever. In this article we focused on habitat, cause of endangerment and conservation methods of Pittosporum eriocarpum, an endangered medicinal plant species (listed in red data book, IUCN). According to WHO report, increasing demand of medicinal plants is expected to reach 5 trillion by the year 2050 in international market. So there are various opportunities for pharmaceutical industry. Our study focuses on conservation strategies regarding the plants habitat and suggesting a creative protocol for its collection, storage and number of medicinal plant species through which we can save or control its endangerment. We also suggest that alternate methods like using advanced biotechnological techniques such as protoplast culture and bioreactors should replace traditional ways of collection of herbal plants from their native habitat which is leading to their endangered status. Key words: Extinction, pharmaceutical industry, ornamental, Pittosporum eriocarpum. 25  Thapliyal et al (2013) Biotechnology International 6(2): 25-30 INTRODUCTION plants and their products particularly essential oils are also becoming more important. Himalaya is one of the biggest hot spots Traditional medicine at the present time is of biodiversity in the world and offers immense accepted as an alternative for the western opportunities in various fields of biological medical practice in many countries. In India, domains and associated patterns of sustainable demand of medicinal plants is estimated at US life support systems (Gaur, 2004). The Indian $ 1 billion per years (Sharma, 2004). There are Himalayan Region is well known to have a various well known medicinal plant species like great range of plant diversity. This region alone Ginkgo biloba, Bacopa monnieri,Withania supports about 18,440 plant species somnifera and Acorus calamus etc but there are (Angiosperm: 8,000 spp., Gymnosperm: 44 some species whose potential is yet to be spp., Pteridophytes: 600 spp., Bryophytes: explored by the scientists. These species of 1,736. Lichens: 1,159 spp. and fungi: 6,900 spp. plants are being used in various traditional (Singh et.al., 1997) According to Samant et. al. medicines by the local peoples, one such (1998), out of the total vascular plant species, species is Pittosporum eriocarpum. 1,748 species are of medicinal uses. In India Pittosporum is a genus of about 200 7500 plant species are used for medicinal species in the Pittosporaceae family and purpose out of 17,000 higher plant species Pittosporum eriocarpum is commonly known (Shiva, 1996). World Health Organization has as Agni. The species has been categorized as an reported in a survey report that 25% of endangered species by the “International Union prescribed human medicines are derived from for Conservation of Nature” (IUCN, 1998 - plants and 80% of the population in developing Walter and Gillett) which is the world's main countries still depends on the traditional and authority on the conservation status of species folk system of medicine (Rawat, 2009).

This plant species has According to WHO, the international been recorded from Shastradhara (Dehradun) market of herbal products is estimated to be US and Musoorie in the state of Uttarakhand $ 62 billion which is poised to grow to US $ 5 (India) (Fig. 1).

Cause of Endangerment of Pittosporum eriocarpum There is no one particular cause for endangerment, but many factors are responsible for triggering the endangerments of this plant species. One of the suggested causes is loss of its natural habitat, due to anthropogenic activities in this geographic region. As the human population grows, the more land mankind needs to comfortably survive. Unfortunately, as this improves the lives of Fig.1 Young Leaves of Pittosporum eriocarpum humans, it threatens the survival of many plant plant species. Many news papers reported loss of The species can be artificially natural plant habitat caused by an increase in regenerated by sowing or layering. It is wild fires. While other blame the global classified as a multipurpose species and is warming. As the temperatures rise, more wild lopped for fodder, fuel wood, suitable for soil fires appear. This causes many plant species to conservation and reclamation of degraded sites lose their natural habitat. Natural disasters also (Singh et. al., 1999).
