|Source:||The herbs of Taxillus sutchuenensis|
|Solvent:||DMSO, 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.

|Flavanone glycosides from viscum coloratum and their inhibitory effects on osteoclast formation.[Pubmed: 21922656 ]|
|Two novel flavanone glycosides, homoeriodictyol 7-O-β-D-[6-(3-hydroxybutanoyl)glucopyranoside] (viscumneoside IX; 1) and homoeriodictyol 7-O-β-D-[6-(3-hydroxybutanoyl)glucopyranosyl](1→2)-β-D-glucopyranoside (viscumneoside X; 2), together with four known flavanoids, 2-homoeriodictyol 7-O-β-D-glucopyranoside (3), viscumneoside I (4), Viscumneoside III (5), and 4',5-dihydroxy-3'-methoxy-7-(2-O-α-L-rhamnopyranosyl-β-D-glucopyranosyloxy)flavanone (6) were isolated from stems and leaves of Viscum coloratum. Their structures were elucidated on the basis of their NMR spectra, HR-FAB-MS data, and acid hydrolysis. Inhibitory effects of the four compounds 1-4 on the formation of osteoclast-like multinucleated cells were investigated. As a result, all the four flavanoids showed significant inhibitory effects on the formation of osteoclast-like multinuclear cells even at a low concentration of 2 μg/ml. The activities of 1-4 at such a concentration exceeded or approximated to that of elcitonin, the positive control drug at a concentration of 2 U/ml, suggesting that they may be of interest for the development of new anti-osteoporosis drugs.|

|In vitro Anti-Tyrosinase Activity of Viscumneoside III and Homoflavoyadorinin B Isolated from Korean Mistletoe (Viscum album)[Reference: WebLink]|
|Various bioactive substances are found in mistletoe, including Viscumneoside III (1) and homoflavoyadorinin B (2), both which inhibit tyrosinase. These two compounds are mainly found in the EtOAc fraction of the mistletoe extract and demonstrate higher rates of tyrosinase inhibition than ascorbic acid, which was used as a control. Our results suggest that mistletoe extracts can be utilized in skin whitening cosmetics.|
