FIG. 1.

(A) Structures of triterpenoid saponins and their aglycone moieties and (B) the high-performance liquid chromatogram of the standardized saponin extract from Chinese P. notoginseng (Burk.) FH. Chen. Glc, β-d-glucose; Rha, α-l-rhamnose; Ara(p), α-l-arabinose (pyranose); Ara(f), α-l-arabinose (furanose); Xyl, β-d-xylose. The analysis was carried out as described in Materials and Methods. The peaks are identified as follows: peak 1, notoginsenoside R1; peak 2, ginsenoside Rg1; peak 3, Re; peak 4, Rb1; peak 5, Rc; peak 6, Rb2; peak 7, Rb3; peak 8, Rd; and peak 9, raloxifene (internal standard).
