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.

Determination of forsythoside E in Tanreqing injection by LC-MS/MS[Reference: WebLink]

To establish a liquid chromatography-tandem mass spectrometric method(LC-MS/MS)for the determination of Forsythoside E in Tanreqing injection.
METHODS AND RESULTS:
After being diluted,the sample was separated on an Agilent SB-C18 column(2.1 mm×15 mm,3.5 μm)for gradient elution with a mobile phase of acetonitrile-0.01% formic acid water-solution at a flow rate of 0.3 mL·min-1.Then the processed sample was analyzed by tandem mass spectrometer with negative-electrospray ionization(ESI)source,monitored under a multiple reaction monitoring(MRM)mode.The calibration curve showed a good linearity in the range of 47.5-950 ng·mL-1.The average recoveries(n=3)of low,middle and high concentrations were 99.0%,103.0%,95.2% with RSDs of 3.4%,1.5% and 1.0%,respectively.The content of Forsythoside E in 13 batches of Tanreqing injection samples was in the range of 0.077-0.145 mg·mL-1.
CONCLUSIONS:
The developed method can be used for the quantitative determination of Forsythoside E in Tanreqing injection.
