||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: firstname.lastname@example.org
||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.

|Isolation and purification of seven compounds from extract of Rheum Palmatum L. by high speed counter current chromatography and rapid preparative chromatography[Reference: WebLink]|
|High speed counter current chromatography (HSCCC) combined with rapid preparative chromatography (RPC) was developed for the separation and purification of seven compounds from Rheum palmatum L. in this paper. |
METHODS AND RESULTS:
Compounds dimmer-catechin, catechin, trans-3,5,4′-trihydroxystilbene-4′-O-β-D-(6′-O-gallayl)-glucoside,
1-O-Galloyl-2-O-cinnamoyl-glucose, rhein and emodin were isolated and purified by HSCCC using an optimized two-phase solvent system composed of n-hexane–ethyl acetate–n-butanol–water (1:2:1:4, v/v/v/v) and RPC. The purities of compounds 1, 3, 4 and 6 from HSCCC separation were over 98.70%, 96.75%, 98.20% and 98.07%, and those of compounds 1, 2, 4, 5 and 7 from RPC separation were 95.33%, 89.40%, 93.7%, 92.89% and 94.76%, determined by HPLC. The HSCCC and RPC fractions were analyzed by HPLC and electrospray ion source mass spectroscopy (ESI-MSn) in negative ion mode. The identification of the seven compounds from the extract of R. palmatum L. was based on matching their retention time, the detection of the molecular ions and the fragment ions of the molecular ion obtained in the MSn experiments with those of the data reported in the literature.
The results demonstrated that HSCCC and RPC are feasible and efficient techniques for systematic isolation of bioactive components from R. palmatum L.
