We reported a new processed ginseng with increased biological activities which is named as “sun ginseng (SG)”. Study on the saponin constituents of SG led to the isolation of seven new ginsenosides named as ginsenoside Rk$_1$, Rk$_2$, Rk$_3$, Rs$_4$, Rs$\_$5/, Rs$\_$6/ and Rs$\_$7/. Ginsenoside Rk$_1$, Rk$_2$ and Rk$_3$ were the Δ$^<$TEX>20(21),24(25)/-diene dammarane compounds, while ginsenoside Rs$_4$, Rs$\_$5/, Rs$\_$6/ and Rs$\_$7/ were mono-acetylated compounds. Many other ginsenosides which were reported as minor constituents of red ginseng were also isolated, which include 20(S)-Rg$_3$, 20(R)-Rg$_3$, Rg$\_$5/, Rg$\_$6/, F$_4$, Rh$_4$, 20(S)-Rs$_3$ and 20(R)-Rs$_3$. The major ginsenosides of SG were 20(S)-Rg$_3$, 20(R)-Rg$_3$, Rk$_1$ and Rg$\_$5/.
