|Biological Activity or Inhibitors:|| 1. Gnetin D exhibits significant in vitro anti-influenza viral activity in MDCK cells, with IC(50) values from 0.67 to 11.99 ug/mL.
|Solvent:||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.|
|Storage:||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.

|After receiving:||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.|

|In vitro anti-influenza viral activities of stilbenoids from the lianas of Gnetum pendulum.[Pubmed: 20539973 ]|
|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 μg/mL in comparison to the positive controls oseltamivir acid and ribavirin whose IC(50) values were 0.040 and 5.54 μg/mL, respectively.|

|Secondary metabolites from Spirotropis longifolia (DC) Baill and their antifungal activity against human pathogenic fungi.[Pubmed: 22137037]|
|A phytochemical study of the ethyl acetate extract of the roots and adventitious roots of Spirotropis longifolia, a monodominant tree species of the Guianan rainforest, has allowed the isolation of three compounds: 2-hydroxy-8,9-methylenedioxy-2',2'-dimethylpyrano-[5',6':4,3]-6a-prenyl-[6aS,11aS]-pterocarpan (spirotropin A), 2-hydroxy-8,9-methylenedioxy-2',2'-dimethyl-3',4'-dihydropyrano-[5',6':4,3]-6a-prenyl-[6aS,11aS]-pterocarpan (spirotropin B), and 5,7-dihydroxy-6,8-diprenyl-2'''',2''''-dimethylpyrano[5'''',6'''': 3',4']-isoflavone (spirotropone). In addition, 10 known compounds, trans-oxyresveratrol, trans-resveratrol, piceatannol, daidzein, genistein, isoprunetin, lupeol, latifolol, Gnetin D and gnetin E, were also isolated. These compounds were evaluated for their antifungal activity and their cytotoxicity, and their structures were established by 1D and 2D NMR, HRMS, CD and optical rotation measurements.|
