摘要: |
Phytochemical investigation of the rhizomes of Panax japonicus C. A. Meyer (Araliaceae) resulted in the isolation of two new dammarane-type triterpenoid saponins, yesanchinoside R1 (1) and yesanchinoside R2 (2), together with one new natural product, 6'''-O-acetylginsenoside Re (3). In addition, 25 known compounds, including 23 triterpenoid saponins, 426, beta-sitosterol 3-O-beta-D-glucopyranoside (27), and ecdysterone (28), were also identified. The known saponins 12, 15, and 1822 were reported for the first time from the title plant. Their structures were elucidated on the basis of detailed spectroscopic analyses, including 1D- and 2D-NMR techniques, as well as acidic hydrolysis. |
