Diversity And Evaluation Of Wild Medicinal Plants Of Minjiangyuan Nature Reserve

The Minjiangyuan Nature Reserve was situated at the southeast of Jianning County in the center-section of Wuyi sierra in Fujian. The main protected object of which were the important biota components, the large native populations of Bretschneidara sinensis and Taxus mairei , the unique biotic community types and the forest cover at the sourse of Minjiang river. Wild medicinal plant resources in Minjiangyuan Nature Reserve were abundant. On the basis of the preliminary scientific expedition in the Nature Reserve, investigations and visits on wild medicinal plant resources had been carried out. Meanwhile, efforts had been made to analyze the diversity of wild medicinal plants and to scienticficly evaluate their conservation and utilization.These would provide a wealth of basic data for Sanming's natural pharmaceutical development.The results were as follows:1. There were 160 families, 519 genera and 878 species of wild medicinal plants in Minjiangyuan nature reserve, including 27 families, 37 genera, 57 species of Pteridophyte, 5 families, 7 genera, 7 species of Gymnosperm, and 128 families, 475 genera, 814 species of Angiosperm.2. Analysis on the flora of Pteridophyte and Spermatophyte showed that the tropical distribution composition (85 families, 53.13%; 263 genera, 50.67%) took more percentage than the temperate distribution composition (37 families, 23.14%; 208 genera, 40.08%) . were the main This flora was composited by tropical distribution composition with some of transition composition.3. The wild medicinal species used by herb and rhizome were the main phytogroup taking the percentage of 44.48 and 38.23 respectively.4. There were 82 families, 164 genera, 204 species of wild medicinal plants with cold property, 80 families, 147 genera, 191 species of that with cool property, 81 families, 162 genera, 212 species of that with warm property, 86 families, 184 genera, 273 species of that with neutral property, and 2 families, 3 genera, 3 species of that with hot property.5. There were 46 families, 85 genera, 105 species of wild medicinal plants with sweet flavor, 86 families, 158 genera, 195 species of that with bitter flavor, 52 families, 85 genera, 105 species of that with acrid flavor, 13 families, 15 genera, 16 species of that with sour flavor, and 16 families, 19 genera, 19 species of that with neutral flavor. The other of wild medicinal plants tasted like more than 2 kinds of flavor.6. There were 126 species of wild poisonous medicinal plants in Minjiangyuan nature reserve. 6 families, 7 genera and 7species of them had strong toxicity. 39 families, 49 genera and 61 species of them had moderate toxicity. 25 families, 47 genera and 59 species of them had mild toxicity.7. The medicinal resources of Compositae was very rich(33 genera, 55 species) with a variety of medicinal function.8. Quantitative evaluation of the rare and endangered medicinal plants showed that some of them needed urgent protection, such as Coptis chinensis var.brevisepala, Dysosma versipellis, Anoectochilus roxburghii, Epimedium sagittatum, , Botrychium ternatum, Cibotium barometz, Ormosia henryi, Fagopyrum cymosum etc.The resources of wild medicinal plants in Minjiangyuan nature reserve were very rich. It was very important to collect and evaluate the resources in time for the protection and utilization of them.
