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? Please email to: service@chemfaces.com

    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.

    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.
