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.

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.

Analysis of flavonoids in Achillea nobilis L. by capillary electrophoresis.[Reference: WebLink]

The separation and quantification of the ftavonoids occurring in Achillea nobilis L by a CE-method is described.
METHODS AND RESULTS:
Using 20 mM sodium borate at pH 9.5 with 20 % of methanol as buffer, the flavonoids were sufficiently separated within 11 minutes. Kaempferol-7-O-neohesperidoside was used as internal standard for the quantification. Analysis of six different samples showed the flavon-C-glycos ides isoorientin, orientin and vitexin as the characteristic main compounds.
CONCLUSIONS:
The contents of fiavon-C-g!ycosides determined by this CE-method correlated with the results achieved by a spectrophotometric determination.
