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.

Anti-inflammatory and anti-tumor-promoting effects of cucurbitane glycosides from the roots of Bryonia dioica.[Pubmed:
11858752]
Seven new triterpene glycosides, bryoniosides A-G (1-7), have been isolated along with two known triterpene glycosides, cabenoside D (8) and bryoamaride (9), from a methanol extract of the roots of Bryoniadioica.
METHODS AND RESULTS:
The structures of 1-7 were determined on the basis of spectroscopic and chemical methods. Six compounds, 2, 3, 5, and 7-9, and 11 compounds, 1-9, Bryodulcosigenin (10), and bryosigenin (11), respectively, were evaluated for their inhibitory effects on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation (1 microg/ear) in mice and on Epstein-Barr virus early antigen (EBV-EA) activation induced by TPA.
CONCLUSIONS:
All compounds tested showed marked anti-inflammatory effects, with 50% inhibitory doses (ID(50)) of 0.2-0.6 mg per ear. In addition, all of the compounds tested except for compound 5 showed potent inhibitory effects on EBV-EA induction (100% inhibition at 1 x 10(3) mol ratio/TPA).
