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.

Source of Viscidulin III

The roots of Scutellaria viscidula Bge.

Biological Activity of Viscidulin III

DescriptionViscidulin III (17.4 microM), wogonin (17.4 microM) and luteolin (18.4 microM) were more effective than baicalein (23.0 microM) which reportedly inhibits the proliferation of some cancer cell lines.
In vitro

Flavonoids from Scutellaria baicalensis and their bioactivities.[Pubmed: 19829679]

Beijing Da Xue Xue Bao. 2009 Oct 18;41(5):578-84.

To study the flavonoids of Scutellaria baicalensis and their bioactivities.
METHODS AND RESULTS:
Chromatographic methods were used to separate compounds, spectral methods were used to determine the structures and bioactivities of the flavonoids were screened in several models in vitro. Nine compounds were isolated and identified as baicalein (1), wogonin (2), oroxylin A (3), 5, 7, 2', 6'-tetrahydroxyflavone (4), Viscidulin III (5), baicalin (6), wogonoside (7), oroxylin A-7-O-beta-D-glucuronide (8) and chrysin-6-C-alpha-L-arabinopyranosyl-8-C-beta-D-glucopyranoside (9).
CONCLUSIONS:
Baicalein had good anti-bacteria activity, and some compounds showed inhibiting activity against IL-1beta converting enzyme. The 13C NMR data of compounds 9 were assigned correctly by 2D nuclear magnetic resonance (NMR).

Cytotoxic activities of flavonoids from two Scutellaria plants in Chinese medicine.[Pubmed: 15036470]

J Ethnopharmacol. 2004 Mar;91(1):65-8.

The effects of 17 flavonoids, isolated from two flavonoid-rich Scutellaria species (Scutellaria baicalensis Georgi and Scutellaria rivularis Wall) used in traditional Chinese medicine, on HL-60 cells were assessed by WST-8.
METHODS AND RESULTS:
Ten of the flavonoids inhibited the proliferation of HL-60, as shown by IC50 values used as indexes of the inhibition. 2',3',5,7-tetrahydroxy flavone (IC50=9.5 microM), apigenin (15.0 microM), Viscidulin III (17.4 microM), wogonin (17.4 microM) and luteolin (18.4 microM) were more effective than baicalein (23.0 microM) which reportedly inhibits the proliferation of some cancer cell lines. Others were less effective, and oroxylin A stimulated the proliferation. Scutellaria rivularis, used for the treatment of tumors in the clinic, contained flavonoids that were more inhibitive than those in Scutellaria baicalensis.
CONCLUSIONS:
These results are demonstrative of some reasons for the use of Scutellaria rivularis as a crude antitumor drug.

Studies on the constituents of roots of Scutellaria planipes.[Pubmed: 17252377]

From the roots of Scutellaria planipes (L.), three new flavonoids, 5,7,3',6'-tetrahydroxy-6,8,2'-trimethoxyflavone, (2 R,3 R)-3,5,7,2',5'-pentahydroxyflavanone and 7,2'-dihydroxy-5-methoxyflavone were isolated, together with ten known flavonoids, skullcapflavone I, wogonin, baicalein, norwogonin, Viscidulin III, 5,7,2',6'-tetrahydroxy-flavone, 3,5,7,2',6'-pentahydroxyflavone, wogonin 7- O-beta- D-glucuronide, baicalin, baicalein 7- O-beta- D-glucopyranoside, and three phenethyl alcohol glycosides, acteoside, martynoside, and jionoside D. The structures were elucidated by spectroscopic methods.
