General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

SEPARATION AND PURIFICATION OF TRITERPENE SAPONINS FROM ROOTS OF RADIX PHYTOLACCAE BY HIGH-SPEED COUNTERCURRENT CHROMATOGRAPHY COUPLED WITH EVAPORATIVE LIGHT SCATTERING DETECTION.[Reference: WebLink]


METHODS AND RESULTS:
Coupled with evaporative light scattering detection, high-speed countercurrent chromatography was successfully applied for the first time for separation and purification of four triterpene saponins including esculentosides A, B, C, and D from the roots of Radix phytolaccae. The separation was performed with an optimized two-phase solvent system composed of chloroform-methanol-water (4:4:2,v/v), using the lower phase as the mobile phase at a flow rate of 1.5 mL/min. From 150 mg of crude extract, 46.3 mg of esculentoside A, 21.8 mg of esculentoside B, 7.3 mg of esculentoside C, and 13.6 mg of Esculentoside D were obtained at purities of 96.7%, 99.2%, 96.5%, and 97.8%, respectively, as determined by HPLC analysis.
CONCLUSIONS:
The structures of the four triterpene saponins were identified by ESI-MS,1H NMR and 13C NMR.
