|Solvent:||DMSO, Pyridine, Methanol, Ethanol, 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.

|Caffeoylated phenylpropanoid glycosides from Brandisia hancei inhibit advanced glycation end product formation and aldose reductase in vitro and vessel dilation in larval zebrafish in vivo.[Pubmed: 24288293 ]|
|In our continuing efforts to identify effective naturally sourced agents for diabetic complications, five caffeoylated phenylpropanoid glycosides, acteoside (1), isoacteoside (2), poliumoside (3), Brandioside (4), and pheliposide (5) were isolated from the 80% EtOH extract of Brandisia hancei stems and leaves. These isolates (1-5) were subjected to an in vitro bioassay evaluating their inhibitory activity on advanced glycation end product formation and rat lens aldose reductase activity. All tested compounds exhibited significant inhibition of advanced glycation end product formation with IC50 values of 4.6-25.7 μM, compared with those of aminoguanidine (IC50=1,056 μM) and quercetin (IC50=28.4 μM) as positive controls. In the rat lens aldose reductase assay, acteoside, isoacteoside, and poliumoside exhibited greater inhibitory effects on rat lens aldose reductase with IC50 values of 0.83, 0.83, and 0.85 μM, respectively, than those of the positive controls, 3,3-tetramethyleneglutaric acid (IC50=4.03 μM) and quercetin (IC50=7.2 μM).|

|In vitro neuroprotective activities of phenylethanoid glycosides from Callicarpa dichotoma.[Pubmed: 16142646 ]|
|Ten phenylethanoid glycosides, forsythoside B, acteoside, 2'-acetylacteoside, poliumoside, Brandioside, echinacoside, isoacteoside, cistanoside H and E-tubuloside E as well as a new compound, Z-tubuloside E, were isolated from the n-BuOH fraction of Callicarpa dichotoma Raeuschel (Verbenaceae) by bioactivity-guided fractionation using glutamate-injured primary cultures of rat cortical cells as a screening system. These phenylethanoid glycosides significantly attenuated glutamate-induced neurotoxicity at concentrations ranging from 0.1 to 10 microM.|

|Purification of phenylethanoids from Brandisia hancei and the antiproliferative effects on aortic smooth muscle.[Pubmed: 11509971 ]|
|The present study describes the isolation and purification of acteoside, 2'-acetylacteoside, poliumoside and Brandioside, four phenylethanoid glycosides from Brandisia hancei. We examined their effects on the proliferation of cultured A7r5 rat aortic smooth muscle cells. The proliferative response was measured from the [(3)H]-thymidine incorporation into DNA. All four glycosides suppressed the proliferative response in the presence of 2 % or 5 % fetal bovine serum in a concentration-dependent manner. The rank order of effectiveness for inhibition of cell proliferation was: Brandioside > or = poliumoside > 2'-acetylacteoside > or = acteoside. The acetyl group at position 2' of glucose does not seem necessary for the anti-proliferative effects of acteoside and 2'-acetylacteoside, while the hydroxy groups of the aromatic rings appear to play a role. Inhibition of smooth muscle cell proliferation by phenylethanoids indicates that these compounds may have preventative effects on arteriosclerosis.|

|Antioxidant activity of phenylethanoid glycosides from Brandisia hancei.[Pubmed: 10940587]|
|Brandisia hancei is a medicinal herb in China. The ethanol extract of this plant and four phenylethanoid glycosides, acteoside (1), 2'-acetylacteoside (2), poliumoside (3) and Brandioside (4), isolated from it were shown to have inhibitory effects on free radical-induced hemolysis of red blood cells and free radical scavenging activities in vitro. Brandioside (4) and poliumoside (3) showed stronger antioxidant effect than acteoside (1), 2'-acetylacteoside (2) and trolox.|
