title: [Catalpol content changes in Rehmannia glutinosa (Gaertn.) Libosch. under certain conditions].
abstract: HPLC determination has shown that the content of catapol in Rehmannia glutinosa decreases markedly after being dried and processed. This change of content is related to acidic and alkaline conditions. But in boiling water or saccharide solution no marked changes have been observed.
