Changes in ginsenoside and total phenolic contents of wild ginseng leaves and their tea products were investigated according to various roasting conditions. Total contents. Total content of ginsenosides, in wild ginseng fresh leaves was 14,23%. Ginsenoside contents, although slightly decreased with increasing repetition of roasting, were relatively heat-stable. Rg₁, Re, and Rd were identified as major ginsenosides in leaves. Ratios of panaxadiol ginsenoside/panaxatriol ginsenoside were in the range of 0.70-0.75.
