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.

Compounds from the roots and rhizomes of Valeriana amurensis protect against neurotoxicity in PC12 cells.[Pubmed:
23250029]
METHODS AND RESULTS:
Three new germacrane-type sesquiterpenoids, Heishuixiecaoline A, heishuixiecaoline B, heishuixiecaoline C (compounds 1-3), were isolated along with ten known compounds 4-13 from fraction of Valeriana amurensis roots and rhizomes effective against Alzheimer's disease (AD). The structures of 1-3 were elucidated on the basis of their spectroscopic data. We also investigated the protective effect of compounds 1-13 on the neurotoxicity of PC12 cells induced by amyloid-beta (Aβ(25-25)), respectively.
CONCLUSIONS:
As a result, germacrane-type sesquiterpenoids 1-4 and lignans 5-7 were seen to afford protection against Aβ-induced toxicity in PC 12 cells. This study will contribute to revealing the chemical basis for the therapeutic effect of V. amurensis against AD.
