Abstract
The effects of the soil properties on the contents of catalpol, sugar and ash in the rhizoma of Ji-whang (Rehmannia glutinosa Lib. var. purpurea Makino) were studied to get information on cultivation for higher quality production. Catalpol contents of the rhizoma of Ji-whang ranged from 3.75 to 4.36%. It was shown that the sand contents of soil was positively correlated with the catalpol contents, and negatively correlated with the contents of fructose and galactose in the rhizoma of Ji-whang. The sand contents of subsoil was also negatively correlated with the contents of ash and acid insoluble ash in rhizoma. The clay contents of subsoil was negatively correlated with the catalpol contents, and positively correlated with the contents of fructose, galactose and sucrose in rhizoma, respectively. The clay contents of soil was positively correlated with the ash contents, and negatively correlated with the contents of ethanol extract and water extract in rhizoma, respectively. The organic matter contents of surface soil and subsoil were negatively correlated with the contents of catalpol and extracts (ethanol and water), and positively correlated with the contents of fructose and ash in rhizoma. The total nitrogen contents of surface soil was negatively correlated with the catalpol contents, and positively correlated with the contents of fructose and sucrose in rhizoma. The potassium contents of soil was highly positively correlated with the fructose contents in rhizoma.
