title: [Effects of soil factor on active components of Radix Ophiopogonis].
abstract: OBJECTIVE
  To study the effects of soil factors on the active components in Radix Ophiopogonis.
  
  
  METHODS
  The content of polysaccharide, flavonoids, saponins, water-soluble extract and inorganic elements in Radix Ophiopogonis gathered from 7 different places were compared, physical and chemical properties and inorganic elements of soil were analyzed. The path and grey connection analysis were applied for studying the effects on the active components of Radix Ophiopogonis.
  
  
  CONCLUSIONS
  The concentrations of mineral elements in plant were mainly adjusted by active absorption. The active components in Radix Ophiopogonis was primarily effected by soil enzyme activity, the other important factors were potassium, pH, and organic matter. K, Fe, Mn, B, Ba, Zn of soil also had much influence on it then others inorganic elements.
