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.

Stability of Sinapine Thiocyanate from Water Extract of Semen Raphani in Artificial Gastric and Intestinal Juice[Reference: WebLink
To investigate the stability of Sinapine thiocyanate in artificial gastric and intestinal juice gained from the water extract of Semen Raphani.
METHODS AND RESULTS:
HPLC was used to determine the area at different time points of Sinapine thiocyanate in artificial gastric juice with or without pepsin and artificial intestinal juice with or without pancreatin, the mass concentration and average remaining percentage were calculated respectively. Sinapine thiocyanate was more stable in artificial gastric juice than in artificial intestinal juice and most unstable in artificial intestinal juice without pancreatin. The stability of Sinapine thiocyanate was similar in two kinds of artificial gastric juice but considerable different in artificial intestinal juice.
The remaining percentage of Sinapine thiocyanate in artificial gastric and intestinal juice, which were relatively stable, were all above 70 %, and that provided reference for the absorption mechanism of Sinapine thiocyanate.

Determination of sinapine thiocyanate in YangHePingChuan granules by UPLC[Reference: WebLink
To establish a method for determination of Sinapine thiocyanate in YangHePingChuan granules by UPLC.
METHODS AND RESULTS:
UPLC method was adopted.The determination was performed on the Acquity UPLC BEH C18(100mm×2.1mm,1.7μm) column with mobile phase consisted of acetonitrile-0.08 mol·L-1 potassium dihydrogen phosphate(13∶ 87)at the flow rate of 0.25mL·min-1.The detection wavelength was set at 326nm and the column temperature was 30℃. The linear ranger of Sinapine thiocyanate was 0.105~1.05μg with an average recovery of 99.55%(RSD=1.82%,n=6).
The method is accurate,reliable,simple and practical,it can be used for the quality control of granules.
