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.

Naturstoffe aus Arzneipflanzen, XXII. Notiz über die Isolierung und Konstitutionsaufklärung eines neuen Picrosids aus Picrorhiza kurrooa Royle und Benth.[Reference:
WebLink]
METHODS AND RESULTS:
Der Extrakt von Picrorhiza kurrooa enthält neben dem von uns isolierten Picrosid-I (6′-Cinnamoylcatalpol, 6-O-Cinnamoylcatalpol,2) und Picrosid-II (6-Vanilloylcatalpol, 3) ein drittes Picrosid, dessen Konstitution als 6′-(4-Hydroxy-3-methoxycinnamoyl)catalpol (4) spektroskopisch bewiesen wird. Außer den drei Picrosiden 2–4 wird ein Gemisch der 6-Cinnamoyl-α- und 6-Cinnamoyl-β-D-glucopyranose isoliert, das sehr wahrscheinlich bei der Aufarbeitung durch Spaltung des Picrosids-I (2) entsteht.Natural Products from Medicinal Plants, XXII. — Note on the Isolation and Elucidation of the Constitution of a New Picroside from Picrorhiza kurrooa Royle and Benth.
CONCLUSIONS:
Besides containing picroside-I (6′-cinnamoylcatalpol, 2) and picroside-II (6-vanilloylcatalpol, 3), previously isolated by us, the extract from Picrorhiza kurrooa includes a third picroside whose constitution has been shown spectroscopically to be 6′-(4-hydroxy-3-methoxycinnamoyl)-catalpol (4). In addition to the three picrosides 2–4 a mixture of 6-cinnamoyl-α-and 6-cinnamoyl-β-D-glucopyranose is isolated which presumably is formed by cleavage of the picroside-I (2) during work-up.
