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. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. 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: service@chemfaces.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.

Separation and Purification of Flavones from Viscum Coloratum (Kom.) Nakai by High-Speed Counter-Current Chromatography.[Reference: WebLink]

METHODS AND RESULTS:
High-speed counter-current chromatography(HSCCC) combined with macroporous adsorption resins was employed to separate and purify flavones from Viscum coloratum(Kom.)Nakai.The two phase solvent system of HSCCC consisted of n-hexane-ethyl acetate-methanol-water(3∶4∶5∶3,volume ratio) with the stationary phase as its upper layer and the mobile phase as its lower layer,coiled column rotate speed was 800 r·min-1,flow rate was 3 mL·min-1,injection volume was 20 mL,sample concentration was 20 mg·mL-1,detection wavelength was 254 nm.
CONCLUSIONS:
Two high-purity compounds,rhamnazin-3-O-β-D-glucoside and homoeriodictyol-7-O-β-D-glucoside(Homoeriodictyol 7-O-glucoside) were obtained with purity of 98.01%,96.10%,respectively. And their structures were identified by HPLC and NMR.
