 Title    Acridonepoxidgehalte in Kalluskulturen von Ruta graveolens und ihre Steigerung durch Mischkultur mit Pilzen.* Accumulation of Acridone-Epoxides in Callus C ultures o f Ruta graveolens Increased by Coculture with Not Host-Specific Fungi  
 Abstract    The classic attempt to find optimum culture conditions lead to hormonautotrophic cultures and to dark grown cultures. We made the new attempt to rise the yield o f rutacridone-epoxides by co­ culture with not hostspecific fungi. Conditions were chosen that only diffusible elicitors could in­ fluence callus tissue. 14 days of coculture mostly caused reduced acridone-epoxide content, growthrate and up to total disappearance of chlorophyll. Within 3 — 7 days o f coculture some fun­ gi induced a significant rise of acridone-epoxide content (up to 50-fold). Culture filtrates o f these fungi showed comparable effects. Our results proved the acridone-epoxides to be phytoalexins. The use o f fungal elicitors could be a new method to increase secondary product accumulation in tissue culture.
