General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

In vitro anti-influenza viral activities of stilbenoids from the lianas of Gnetum pendulum.[Pubmed:20539973]

Planta Med. 2010 Nov;76(16):1874-6.

The anti-influenza viral activities of six stilbenoids from the lianas of Gnetum pendulum C. Y. Cheng were evaluated with two different assays, neuraminidase (NA) activity assay and cytopathic effect (CPE) reduction assay. The NA assay results showed that all six stilbenoids exerted an NA inhibitory effect, while the CPE assay indicated that among them, isorhapontigenin (2), gnetupendin B (3), Shegansu B (4), and gnetin D 6) exhibit significant in vitro anti-influenza viral activity in MDCK cells, with IC(50) values from 0.67 to 11.99 microg/mL in comparison to the positive controls oseltamivir acid and ribavirin whose IC(50) values were 0.040 and 5.54 microg/mL, respectively.

A new stilbene dimer--shegansu B from Belamcanda chinensis.[Pubmed:11256690]

J Asian Nat Prod Res. 2000;2(3):169-75.

A new dimeric stilbene, named Shegansu B (1) was isolated from the ethanolic extract of the roots of Belamtantida chinensis (L.) DC., along with the known compounds isorhapontigenin, resveratol, p-hydroxybenzoic acid, iridin, tectoridin, tectorigenin and daucosterol. The structures were elucidated by means of spectroscopic evidence including 2D-NMR studies.
