Abstract: A combination measurements technique of HMBC and TOCSY for the determination of sugar sequence in the ginsenosides is presented, and their use illustrated with examples of structure elucidation of gypenoside ⅩⅦ(1) and ginsenoside L3 (2). The method provided the organic chemist powerful tools for elucidation of oligo-glycoside.

Key words: TOCSY, Quinquenoside L3, Gypenoside ⅩⅦ
