| 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. Need more advice on solubility, usage and handling?

| 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. |

| Subsequently, the newly developed system was applied to screening of a natural product, Oroxylum indicum extract, and four compounds which could specifically interact with XO were found and identified as Oroxin B, oroxin A, baicalin, and baicalein. The results were verified by a competitive binding test using the known competitive inhibitor allopurinol and were further validated by an inhibition assay in vitro. The online RAM-LC-DAD system developed was shown to be a simple and effective strategy for the rapid screening of bioactive compounds from a complex mixture. | |

| Twenty compounds were isolated and identified as oroxin A (1), Oroxin B (2), chrysin (3), baicalein (4), quercetin (5), apigenin (6), kaempferol (7), quercetin-3-O-ara-binopyranoside (8), lupeol C9), lup-20 (29)-ene-2alpha,3beta-diol (10), pinosylvin (11), dihydropinosylvin (12), cholest-5-ene-3, 7-diol (13), rengyol (14), isorengyol (15), zarzissine (16), (E) -pinosylvin-3-O-beta-D-glucopyranoside (17), adenosine (18), sitosterol (19) and daucosterol (20). CONCLUSION: Compounds 11-13 and 15-18 were obtained from the genus Oroxylum for the first time, and except compound 18, the remaining 6 compounds were obtained from the family Bignoniaceae for the first time. |
