ABSTRACT
Shikimic acid is a phenolic acid which is known to possess several activities and it takes attention as a leading com-pound to some synthetic medicinal substances as well. In this study, high performance liquid chromatographic analyses were carried out in order to determine shikimic acid contents of Alnus glutinosa subsp. glutinosa, A. orien-talis var. orientalis and A. orientalis var. pubescens; acetonitrile and 0.2% o-phosphoric acid:water mixture with isocratic flow was used as mobile phase. The flow rate was 0.5 ml/min. The quantitative analysis of methanol extracts prepared from the leaves of A. glutinosa subsp. glutinosa, A. orientalis var. orientalis and A. orientalis var. pubescens revealed that shikimic acid amount was found to be 0.6491%, 0.4309% and 0.2452% respectively.
