This dissertation is focusing on the structure design, chemical synthesis and bioactivity study of active saponin derivatives.

The open reading frame of GBR6, a novel candidate gene involved in ginsenoside biosynthesis was amplified by RT PCR, and was directionally subcloned to pQE30 vector.

However, little is knownabout the molecular mechanisms in the ginsenoside biosynthesis process.
