20-O-Glucoginsenoside Rf Description
||The roots of Panax ginseng C. A. Mey.
||DMSO, Pyridine, Methanol, Ethanol, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day.

Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: email@example.com
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Further studies on dammarane-saponins of Sanchi-Ginseng[Reference: WebLink]|
|Three new saponins, named notoginsenosides-R3 (11), -R4 (12), and -R6 (13) were isolated from Sanchi-Ginseng, roots of Panax notoginseng.
METHODS AND RESULTS:
The structures of these saponins were established as 20 (S)-protopanaxatriol 6-O-β-D-glucopyranosyl-20-O-β-D-glucopyranosyl (1→6)-β-D-glucopyranoside (11), 20 (S)-protopanaxadiol 3- [O-β-D-glucopyranosyl (1→2)-β-D-glucopyranosyl]-20-O-β-D-xylopyranosyl (1→6)-β-D-glucopyranosyl (1→6)-β-D-glucopyranoside (12), and 20 (S)-protopanaxatriol 6-O-β-D-glucopyranosyl-20-O-α-D-glucopyranosyl (1→6)-β-D-glucopyranoside (13), respectively. Besides these saponins, two known saponins, 20-O-Glucoginsenoside Rf (9) and gypenoside XVII (10), were also isolated and identified. From corms of this plant, ginsenosides-Rb1 (1), -Rb2 (26), -Rd (2), -Re (3), -Rg1 (4), and notoginsenoside-R1 (5) were isolated in relatively high yields.
