Abstract:Six saponins were isolated from the fruit pedicels of Panax notoginseng. Five of them were identified as gypenoside-ⅩⅦ,-ⅩⅤ, ginsenoside-Rb_1, and notoginsenoside-Fc, -Fa on the basis of chemical methods, spectroscopic analysis and comparison with authentic standards. Quantitative determination of the major saponins in fruit pedicels from the plant was made by thin layer chromatography-densitometry.
