Spatial structure and geographic distribution of major active component in medical herb Dipsacus asperoides population / 中国中药杂志

ABSTRACT

To study the spatial structure and geographic distribution of major active components in medical herb Dipsacus asperoides population, in Guizhou province, the author obtained the asperosaponin VI content among 38 D. asperoides population points. Using spatial statistic and traditional statistic, the spatial variation pattern has been found. Combining the environment variables, it is tried to reveal the geographic distribution rules between group of major active component in medical herb D. asperoides population and group of environmental factors. The results show: the spatial structure of major active component in medical herb D. asperoides population is randomly distributed in global space, but has two aggregation points which have a high positive correlation in local space; environmental factors value for group of major active component in medical herb D. asperoides population has a large difference in the interior-group, but environmental factors value has a small difference in inter-group.
