The rapid appraisal method was used to identify the botanicals used ethnomedicinally from a total of 300 randomly selected respondents drawn from the existing three geo-political zones of Ekiti State, Nigeria. The results obtained revealed that about 40% of the 71 botanicals identified presently rare. Most of the presently abundant botanicals are species primarily cultivated for other purpose other than medicine. Most of the identified species are valued for their curative effects on malaria and fever, the predominant diseases in the study area. The need for the conservation of the rare species cannot be over emphasised as most rural dwellers in the study area depend mostly on herbs from these species. Strategies towards the attainment of this goal are proposed.

This paper presented a study on the dynamic of essential oil accumulation in Japanese mint SK33 (M. arrvensis L.) and the influence of storage time on its quantity and quality. This mint was cultivated at Co Nhue experimental station, Tu Liem district, Ha Noi City between 2000 and 2002. The results showed that during the vegetation and development process, the essential oil content in the plant gradually increased and achieved maximum at first branch flowering stage and reduced to minimum at the end of flowering stage. The menthol content in essential oil of Japanese mint SK33 reached the highest value at full flowering stage (81.79%). The best harvest time for this mint is from the beginning flowering stage to full flowering period. After harvesting the whole plants can be stored during 20 days without the change in content and quality of essential oil

Collected and preserved germplasm resource of Dendrobium chrysotoxum to lay the foundation for screening fine germplasm. Through refering literatures, visiting and field survey to investigate the distribution, botanic characters and apply status of D. chrysotoxum, furthermore to collect the germplasm resource. The result show that wild germplasm resource of D. chrysotoxum has obvious differences in stem characters, leaf shape as well as flower color aspects. In addition, in recent ten years, the reserves of D. chrysotoxum germplasm resource seriously descended. Through this study, we can draw a conclusion that D. chrysotoxum germplasm resource exist diversity in biology. In these germplasm resource, there are high yield and good quality variety.

This study was conducted to investigate the wild and cultivated resource situation of Rheum tanguticum in main production area of China, estimate its reserves, and put forward the feasible approach for the sustainable utilization of R. tanguticum. On the basis of the literature data about R. tanguticum, conbined with interview, investigation and sampling investigation, the total reserve of resources is estimated using the route-quadrat method and the vegetation and soil-type map area method proposed by our research group. The results indicate that there is no obvious change between the present distribution ranges of the wild R. tanguticum and its historical records, but its population density has changed clearly. The reserve of the wild R. tanguticum has seriously declined in lots of place, even faced the exhaustion in some regions. According to the investigation, the resource reserve of the wild R. tanguticum is no more than 5 000 t, and the cultivated is about 1 607 t. The resource reserve of the wild R. tanguticum is nearly depleted, and this suggests that the wild R. tanguticum should be enrolled in the protection plant list, and the cultivated will become the main resource of Rhubarb in the future. So it is extremely neccessary to collect and protect the germplasm resource of R. tanguticum, establish the germplasm nursery and repository, and conduct breeding research on those bases.

OBJECTIVETo investigate the common resource of Chinese herbal medicine in western of Luoding City, Guangdong Province, and propose pertinent suggestions concerning the exploitation,utilization and conservation of the medicinal resources.

METHODSWith plant taxonomy method, we selected the JiaYi town as the center for local common Chinese herbal medicine resources, ecological environment and non-governmental investigation of medicinal.

RESULTSThere were 123 species of medicinal plants in Jiayi Town, including pteridophyte 11 species, gymnosperm 5 species, dicotyledon 97 species,and monocotyledon 12 species.

CONCLUSIONThis region has an excellent ecological environment and forest plant communities preserved relatively intact suitable for the growth of Lingnan Chinese herbal medicine, as well as a profound cultural background of folk medicine. The resources should be actively protected for further rational development and utilization.

The 9th Global Conference for Health Promotion has been held in Shanghai after 30 years of the first Global Conference for Health Promotion in Ottawa, Canada. In the conference, the delegated members of the countries declared ‘Shanghai Declaration on promoting health in the 2030 Agenda for Sustainable Development.’ In the declaration, the delegated members of country had agreed that health is one of the ‘most effective markers’ of any city's successful sustainable development and contributes to make cities inclusive, safe, and resilient for the whole population and ‘health literacy’ empowers individual citizens and enables their engagement in collective health promotion action. And in a parallel session ‘Mayors Forum’, they had consensus for health city and they adopted ‘Shanghai Consensus on Healthy Cities’. They recognized their political responsibility to create the conditions for every resident of every city to lead more healthy, safe, and fulfilling lives and to support the full realization of human potential and capabilities at all ages in the city environment.

OBJECTIVETo further investigate and discuss the cause of species endangerment, the status and present problem of conservation of traditional Tibetan medicine in China.

METHODPrevious relevant investigations and literatures were summed up in the field. The present situation of conservation of traditional Tibetan medicine was analyzed.

RESULTThe status of endangered resources, cause of species endangerment, the conserving status and conserving measures etc were elaborated. The classification was made and suggestion of species conservation of traditional Tibetan medicine were put forward.

CONCLUSIONThe endangered species conservation of traditional Tibetan medicine was carried out by building protective area of endangered species resources and plant garden, setting up germplasm bank, developing the domestication and cultivation of Tibetan medicinal herbs most in use, strengthening the investigation and study of endangered species, launching exchange and cooperation of conservation techniques on endangered species, enhancing the protective awareness of endangered species traditional Tibetan medicine etc. By so doing we can facilitate the sustainable development of traditional Tibetan medicine in China.

Traditional Chinese medicinal resource survey method is time-consuming, strenuous, and having great human influence, the precision is not high enough. This paper, by using spatial information technology, carries on spatial sampling survey for wild medicinal plants resource for generous species to arrange the quadrat scientifically and estimate the suitable area, reserve precisely of medicinal plants. It not only improves the survey precision, but reduces the workload of field survey and provides scientific basis for survey method of pilot work on the fourth national traditional Chinese medicinal resource census.
