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.

Isolation and Purification of Three Flavonoids from the Hawthorn Leaves by High Speed Countercurrent Chromatography, Combined with Isocratic Preparative Reversed-Phase High Performance Liquid Chromatography.[Reference: WebLink]


METHODS AND RESULTS:
Three flavonoids including 4″′-O-rhamnosylrutin, 2″-O-rhamnosylvitexin, and 4″-O-glucosylvitexin were isolated and purified from the hawthorn leaves by high speed countercurrent chromatography (HSCCC), combined together with isocratic preparative reversed-phase high performance liquid chromatography. Analytical HSCCC was used for the preliminary selection of a suitable solvent system composed of n-butanol-water (1:1, v/v). After two useful fractions were obtained by HSCCC using the optimal solvent system, one of them, fraction II, was further purified by reversed-phase semipreparative high performance liquid chromatography.
CONCLUSIONS:
From 500 mg partially purified extract of the hawthorn leaves, 188.4 mg 2″-O-rhamnosylvitexin, 28.5 mg 4″′-O-rhamnosylrutin, and 55.3 mg 4″-O-glucosylvitexin with purities of over 97%, respectively, were obtained. The structure identification of all pure fractions was carried out by UV, MS, 1H NMR and 13C NMR.
