Abstract

Cell Suspension cultures of Thamnosma montana were grown in Gamborg B5 medium which was best suited for acridone alkaloid formation. From the lyophilized cell material nine acridones and three acridone-monoglucosides have been isolated which were found for the first time in the genus Thamnosma. Moreover, N-methylacridone which is known from the intact plant was found. Gravacridonol monoglucoside was identified as a new alkaloid. Interestingly, most isolated alkaloids belong to the dihydrofuroacridones.

Key words
