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.

A new prenylated flavonol from the roots of Sophora flavescens.[Pubmed:
9868163]
METHODS AND RESULTS:
A new prenylated flavonol, sophoflavescenol (1), together with five known flavonoids, kurarinol, Kushenol K, kushenol H, trifolirhizin, and kuraidin, were isolated from the roots of Sophora flavescens. The structure of 1 was determined by spectroscopic analysis.
CONCLUSIONS:
Among the five known flavonoids, kurarinol, Kushenol K, and kushenol H showed weak antiviral activity against Herpes simplex virus types I and II.

Na+-glucose cotransporter (SGLT) inhibitory flavonoids from the roots of Sophora flavescens.[Pubmed:
17374486]
METHODS AND RESULTS:
The methanol extract of Sophora flavescens, which is used in traditional Chinese medicine (sophorae radix), showed potent Na(+)-glucose cotransporter (SGLT) inhibitory activity.
CONCLUSIONS:
Our search for active components identified many well-known flavonoid antioxidants: kurarinone, sophoraflavanone G, Kushenol K, and kushenol N.

A prenylated flavonol, sophoflavescenol: a potent and selective inhibitor of cGMP phosphodiesterase 5.[Pubmed:
12161123]
METHODS AND RESULTS:
During the search for naturally occurring cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5) inhibitors, it was found that the extracts from Sophora flavescens exhibit potent inhibitory activity against cGMP PDE5 prepared from rat diaphragm. Therefore, the inhibitory activities of five flavonoids, kushenol H (1), Kushenol K (2), kurarinol (3), sophoflavescenol (4) and kuraridine (5), isolated from S. flavescens were measured against cGMP PDE5 to identify potent cGMP PDE5 inhibitory constituents.
CONCLUSIONS:
Among tested compounds, sophoflavescenol (4), a C-8 prenylated flavonol, showed the most potent inhibitory activity (IC(50)=0.013 microM) against cGMP PDE5 with 31.5- and 196.2-fold selectivity over PDE3 and PDE4, respectively. Kinetic analysis revealed that sophoflavescenol was a mixed inhibitor of PDE5 with a K(i) value of 0.005 microM.
