ABSTRACT
The fourth time national survey of Chinese materia medica (CMM) was used. The quadrat survey contained recording on species and amounts of plants, collection of specimens and CMM. The weight of main medicinal plant was measured. The quadrat numbers were calculated on regions, plant species and sea level of samples from different regions. There were 703 species of medicinal plants. The 143 species of main medicinal plants, which occupied to 74.5% in main medicinal plants in Chongqing, belonged to 71 families and 132 genera. There were 128 species of wild main medicinal plants. The 30 species of main medicinal plants were cultivated (including 15 species of both wild and cultivated medicinal plants). Among them, 14 species were in large-scale cultivation. This investigation helped the understanding of present situation of medicinal species distribution in Chengkou County, the habitats of wild medicinal plants, and the resources reserves, which provided references for the continuous development of Chinese herbal medicine resources.
ABSTRACT
<p><b>OBJECTIVE</b>To establish seedling classification criteria of Coptis chinensis.</p><p><b>METHOD</b>The height of plant, leaf number, leaf length, leaf wide, weight of leaf, weight of root were measured, the main measurement indexes of seedlings of C. chinensis were chosen through correlation and regression analysis. The seedling classification criteria were formulated by dynamic clustering analysis.</p><p><b>RESULT</b>The criteria of the 1st-grade seedlings were as follows: leaf number above 8 leaves, height of plant between 12 and 14 cm. The criteria of the 2nd-grade seedlings were as follows: leaf number between 6 and 8 cm, height of plant between 9 and 12 cm. The criteria of the 3rd-grade seedlings were as follows: leaf number between 4 and 6 cm, height of plant above 9 cm.</p><p><b>CONCLUSION</b>The seedling classification criteria of C. chinensis was scientific and feasible, and can be used for the quality control standard of C. chinensis.</p>

<p><b>OBJECTIVE</b>To study the dynamic accumulation of the effective components and biomass of Coptis chinensis, so to provide the experimental date of optimal harvest time for C. chinensis in Hongya county.</p><p><b>METHOD</b>The samples of three to five years were gathered from the same field and time. The biomass was analyzed by weighed. The jatrorrhizine, columbamine, epiberberine, coptisine, palmatine and berberine in C. chinensis were analyzed by HPLC.</p><p><b>RESULT</b>With the increasing of years of growth, the rootstalk biomass of C. chinensis was increasing continuously. The biomass growth of four-year-old C. chinensis was the fastest in the year. From September to October was the fastest season of the growth of rootstalk. The dynamic accumulation in rootstalk C. chinensis had regularity in the certain extend. The contents of six alkaloids and all alkaloids in 4-year-old C. chinensis were more than that in 3-years-old and 5-year-old. The contents of six alkaloids were mostly highest in August. From July to December, there is no significant difference in the contents of columbamine, epiberberine, coptisine, palmatine, berberine and all alkaloids in 4-years-old C. chinensis.</p><p><b>CONCLUSION</b>According to the biomass and the accumulation pattern of the effective components in the C. chinensis, the optimal harvest time is from September to October of 4-year-old C. chinensis.</p>
