The family Apiaceae( Umbelliferae) includes some of the world's most important medicinal plants,with more than 100 species recorded in the traditional Chinese medicine,of which more than ten species are commonly used medicinal materials. However,due to morphological similarities,high market demands and regional factors,substitutes and adulterants are often mixed with genuine in the medicinal market. Therefore,a comprehensive sorting for these poorly known plants has been done in this study by combining market survey with literature review,including its species,distribution,price and substitutes. According to the statistics,there are 65 genera and 262 species of medicinal plants of Apiaceae in China,with medicinal part mostly from radix and rhizoma. Sichuan province is the most abundant in distribution and planting resources,with about 137 species,followed by Yunnan,Hubei and Gansu provinces.Furthermore,we summarized the genuine and substitutes of 11 medicinal plants,e. g. Bupleurum,Angelica and Peucedanum etc.,which found that the medicinal plants of Apiaceae were substituted or mixed in different taxonomic ranks. This study would contribute to reduce the risk of medicine misuse,as well as explore other plants of Apiaceae with potential medicinal value,to achieve sustainable development of related industries.

By the fourth survey of Chinese medicinal resources, new medicinal plants records of 2 genera and 5 species were reported in Tibet. They are two genera Rhynchoglossum and Asteropyrum, and five species including Rh. obliquum, A. peltatum, Urena repanda, Schefflera khasiana and Mimulus tenellus. All the voucher specimens are preserved in Herbarium of Tibet Agriculture and Animal Husbandry University.

OBJECTIVETo review the species and distribution of the medicinal plants peculiar to Guizhou and provide evidence for application, protection and collection.

METHODOpen-air investigation, data collection and specimen identification.

RESULTMore than eighty kinds of the medical plants peculiar to Guizhou have been identified.

CONCLUSIONGuizhou has a diversity of medicinal plants. The area of distribution of most species is restricted and the population is small. Some of the species have higher medicinal and scientific research values.

OBJECTIVETo investigate the origin of medicinal plants in Guizhou province, revise the incorrectly recorded species, and correct the erroneous and incomplete Latin names.

METHODExamination was implemented on species, Latin name and geographical distribution of medicinal plants recorded in 'Medicinal Material Resources of Guizhou'.

RESULTIt was found that 98 species and 4 varieties were absent in Guizhou province or their Latin names were incorrect in 17 families.

CONCLUSIONThe origin of medicinal plants in Guizhou province was studied and the incorrect Latin names were revised. It provides a basis for standardization of medicinal plants in Guizhou province.

AIMTo evaluate the similarity between two chromatographic fingerprints automatically with computer.

METHODSChromatogram can be treated as vector of hyperspace, and the similarity between them can be counted according to vectorial angle formula. This process was performed with software written in Visual Basic 6.0. The two main functions of this software are automatic peak tracking in two fingerprints under the same analytic condition and computing the similarity automatically.

RESULTSThe HPLC fingerprints of eleven kinds of Evodia rutaecarpa (Juss.) Benth (a traditional Chinese herb) from different sources were obtained and the similarities were calculated with this software. This method was shown to be a good way to evaluate the similarity between two fingerprints. A sample washed seven times with hot water can be clearly discriminated from other samples of Evodia rutaecarpa (Juss.) Benth with similar results.

CONCLUSIONThis method is a good way to evaluate the similarity between two fingerprints and is helpful in quality control of traditional Chinese medicine.

This paper firstly introduces the concept, method and current research of molecular phylogeography and then discusses its application in the study of geoherbs. The relativity between three genetic differentiation patterns of plant inferred by molecular phylogeography (i.e. allopatric fragmentation, restricted gene flow with isolation by distance and range expansion) and the formation of genuine character is analysed. Molecular authentication of geoherbs based on molecular phylogeography has the advantage of former molecular identification at technology and knowing genetic differentiation of geoherbs. Using molecular phylogeography for study on changing history of geoherbs habitat is also explicated. The problem of germplasm degeneration in cultural geoherbs could be effectively resolved by molecular phylogeography method. The application of molecular phylogeography in these subjects opens up prospects for study on geoherbs by using the principle and method of molecular phylogeography.

OBJECTIVETo investigate the correlation between entophytic fungal community, habitations and varieties of Ligusticum.

METHODThe solidified potato dextrose agar (PDA) of plates was applied for the isolation of the endophytic fungi, and the identification was completed by spot-planting method.

RESULTFifty strains of the entophytic fungi were isolated from the rhizome of L. chuanxiong collected from 6 habitations. They were morphologically identified as belonging to 13 genera, 4 families, 3 orders and 1 class.

CONCLUSIONThere were some differences at quantity, species and distributing of the entophytic fungi in different habitats and varieties of Ligusticum, which was suggested that entophytic fungal community is related with specific habitat.

Dao-di herbs are the Chinese herbs which have high quality and best clinic effects. Sichuan is one of the proviences most rich in Chinese herb resources,which has 7 290 species of Chinese herbs, such as Curcumae Longae Rhizoma, Chuanxiong Rhizoma, Aconiti Lateralis Radix Praeparata, Ophiopogonis Radix, Coptidis Rhizoma, Gentianae Radix, Rhei Radix et Rhizoma, Curcumae Rhizoma, Gardeniae Fructus, ect. After textual research on materia medica of the 7 290 Chinese herbs, we find there are 86 Dao-di herbs in Sichuan, such as Chuanxiong Rhizoma from Dujiangyan, Aconiti Lateralis Radix Praeparata from Jiangyou, Fritillariae Radix, Notoptergii Rhizoma et Radix, Angelicae Dahuricae Radix from Suining, Ophiopogonis Radix from Santai, Salviae Miltiorrhizae Radix et Rhizoma from Zhongjiang, Magnoliae Officinalis Cortex from Pingwu. In China more attention is paid to the production of Dao-di herbs. In 2018, the State Administration of Traditional Chinese Medicine launched the "Construction Plan of national production base of genuine medicinal materials". Developing genuine medicinal materials in genuine production areas is one of the effective ways to ensure the quality of medicinal materials. Based on the study of geographical environment and ecological factors(altitude, climate, soil) in Sichuan province. The Dao-di herbs of Sichuan province are divided into 4 districts, including, Sichuan basin medicinal materials production area, mountain and the basin edge medicinal materials production area, Panxi medicinal materials production area, Plateau Mountain Canyon medicinal materials production area. The suitable regions and best suitable regions of the 86 Dao-di herbs in Sichuan are determined by remote sensing and GIS spatial analysis of the suitable environmental indicators of these Dao-di herbs. Our study is beneficial to the rational distribution of the production and to improvement of the quality of traditional Chinese medicine in Sichuan province.
