Ginsenosides are the main active constituents in Panax ginseng, and the main ginsenosides can be derived from every part of the plant. More than 30 ginsenosides have been isolated from Panax ginseng, most of which contain one of 4 aglycone moieties. However, several studies on the ginsenoside contents of the other parts of Panax ginseng have been reported, and there are some studies on the variation of ginsenoside structures in different parts of the Panax species. Although the most commonly used parts of ginseng are the roots and rhizomes, ginsenosides are also present in the aerial parts of Panax species. However, the underground and aerial parts generally show different ginsenoside profiles. The components and pharmacological properties of ginseng leaf are not completely understood. More interestingly, some reports indicate that the content of active components in the leaf is higher than that in the root. In this study, we propose a microwave processing method of ginseng leaves to increase the contents of ginsenoside Rg6, Rk3, Rh4. The ginsenosides Rg6, Rk3 and Rh4 were not detected in the ginseng leaf extracts, but microwave-processed method of ginseng leaf extract to be included their contents were 16.5, 26.7, and 30.0 mg respectively.
