|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.|

|Inhibition of enterovirus 71 replication by chrysosplenetin and penduletin.[Pubmed: 21914477]|
|Here we investigated the anti-EV71 activity of chrysosplenetin and Penduletin, two o-methylated flavonols isolated from the leaves of Laggera pterodonta. These two compounds were found to have strong activity in vitro against EV71 with low cytotoxicity. In the cytopathic effect (CPE) inhibition assays, both plaque reduction assay and virus yield inhibition assay, the compounds showed a similar 50% inhibitory concentration (IC(50)) value of about 0.20 μM. The selectivity indices (SI) of chrysosplenetin and Penduletin were 107.5 and 655.6 in African green monkey kidney (Vero) cells, and 69.5 and 200.5 in human rhabdomyosarcoma (RD) cells, accordingly.|

|Flavonoids inhibit angiogenic cytokine production by human glioma cells.[Pubmed: 21170924]|
|VEGF and TGF-β1 levels were dosed by ELISA in a GL-15 cell line treated with bevacizumab and also with the flavonoids rutin, 5-hydroxy-7,4'-dimethoxyflavone, casticin, apigenin and Penduletin. Rutin reduced the VEGF and TGF-β1 levels after 24 h but not after 72 h. The other flavonoids significantly reduced TGF-β1 production. Bevacizumab reduced only the VEGF levels in the supernatant from GL-15 cultures. These results suggest that the flavonoids studied, and commonly used in popular medicine, present an interesting subject of study due to their potential effect as angiogenic factor inhibitors.|

|Antiinflammatory and lipoxygenase inhibitory compounds from Vitex agnus-castus.[Pubmed: 19173281]|
|Several secondary metabolites, artemetin (1), casticin (2), 3,3'-dihydroxy-5,6,7,4'-tetramethoxy flavon (3), Penduletin (4), methyl 4-hydroxybenzoate (5), p-hydroxybenzoic acid (6), methyl 3,4-dihydroxybenzoate (7), 5-hydroxy-2-methoxybenzoic acid (8), vanillic acid (9) and 3,4-dihydroxybenzoic acid (10) were isolated from a folkloric medicinal plant, Vitex agnus-castus. The structures of compounds 1-10 were identified with the help of spectroscopic techniques. Compounds 3-10 were isolated for the first time from this plant. These compounds were screened for their antiinflammatory and lipoxygenase inhibitory activities.|
