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.

Chromone glycosides from Knoxia corymbosa.[Pubmed: 17135054]

J Asian Nat Prod Res. 2006 Oct-Nov;8(7):663-70.

Four new chromone glycosides, corymbosins K1-K4 (3-6), together with two known compounds, Noreugenin (1) and undulatoside A (2), were isolated from the whole plant of Knoxiacorymbosa (Rubiaceae).
METHODS AND RESULTS:
The structures of the new compounds were established through extensive NMR or X-ray spectroscopic analysis as 7-O-beta-D-allopyranosyl-5-hydroxy-2-methylchromone (corymbosin K1, 3), 7-O-beta-D-6-acetylglucopyranosyl-5-hydroxy-2-methylchromone (corymbosin K2, 4), 7-O-[6-O-(4-O-trans-caffeoyl-beta-D-allopyranosyl)]-beta-D-glucopyranosyl-5-hydroxy-2-methylchromone (corymbosin K3, 5) and 7-O-[6-O-(4-O-trans-feruloyl-beta-D-allopyranosyl)]-beta-D-glucopyranosyl-5-hydroxy-2- methylchromone (corymbosin K4, 6). Compounds 2-5 were subjected to test their immunomodulatory activity invitro.

New Chromone Alkaloids from the Stem Bark of Schumanniophyton magnificum.[Pubmed: 17265261]

Fractionation of a methanolic extract of the stem bark of SCHUMANNIOPHYTON MAGNIFICUM yielded large quantities of mannitol. In addition, Noreugenin and ten related chromone alkaloids were isolated. Seven of these alkaloids had been isolated previously from S. MAGNIFICUM and one other from S.PROBLEMATICUM but two of the alkaloids were novel, one was hydroxy- N-methylschumannificine and the other was the acetate of N-demethylrohitukine. The structures of the two alkaloids have been deduced from their spectral features.
