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.

Optimized extraction process of formula granules for seeds from Desurainia sophia fried without additional ingredients by Box-Behnken response surface method.[Reference: WebLink]

To optimize extraction process of formula granules for seeds from Desurainia sophia fried without additional ingredients by the Box-Behnken response surface method.
METHODS AND RESULTS:
Several influentialfactors of extraction process were investigated by single factor experiment using UV-spectrometry,with ultrasonic power,time,temperature,and ratio of water as evaluating indexes. The conditions of the extraction were evaluated by total flavonoids of seeds from D. sophia fried without additional ingredients. Based on single factor test,three parameters were chosen to optimize the extraction process. The effects on the yield of flavonoids were analyzed by the response surface methodology,and experiments designed by the Box-Behnken method. Finally,the cream rates as well as contents of Quercetin 3-O-beta-D-glucose-7-O-beta-D-gentiobiosiden and sinapine thiocyanate were determined by HPLC as evalluation indexes. The software of Design-Expert 8. 0. 5 was used to statistically analyze the optimal extraction process. The optimal time,temperature,power,and water ratio predicted by response surface test and quadratic regression model were: 70 ℃,400 W,and 34 m L·g~(-1).
CONCLUSIONS:
The optimum extraction process of formula granules for the seeds from D. sophia fried without additional ingredients is reliable,and its precision is high,which provides a reference to draft national standards and industry standards.
