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.

Structure Identification

International Journal of Mass Spectrometry, 2012, 315(1):46-54.

Collision induced dissociation study of the major components of silymarin.[Reference: WebLink]

The fragmentation properties of the major silymarin constituents, including silydianin, silychristin A and Silychristin B , silybin A and B and isosilybin A and B were studied by energy-dependent collision-induced dissociation (CID) technique.
METHODS AND RESULTS:
The survival yield (SY) method was applied to compare the fragmentation behavior of the various silymarin components. MS/MS spectra were recorded at collision energies which correspond to about 50% survival yield (CE50) and about 1% survival yield (CE01). The laboratory frame collision energy dependence of the fragmentation was studied on the basis of the breakdown curves, i.e., the relative intensities of fragment ions versus collision energy.
CONCLUSIONS:
The fragmentation of silybins and isosilybins is distinct in spite of the minimal difference between their structures. This phenomenon, which is the basis of their analytical identification, is explained in details for the first time, on the basis of the energy-dependent MS/MS experiments and the conformational analysis.
