|Source:||The leaves of Cassia angustifolia.|
|Solvent:||DMSO, Pyridine, Methanol, Ethanol, etc.|
|Storage:||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.

|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.|

|Stability of Active Ingredients from Rheum officinale in Concentration and Drying Process.[Reference: WebLink]|
|To study on stability of active ingredients from Rheum officinale in concentration and drying process.Method:Taking active ingredients from extraction fluid of R.officinale as studying target,samples were taken at different time points in concentration and drying progress,change trends of relative content was determined by HPLC.Result:The relative content of active ingredients were degraded greater degree after concentrated 1 h in process of heating at 70 ℃,its reduction is not obvious after concentrated 2 h by comparing with 1 h,but after concentrated for 3 h,the relative content reduced significantly;At 70 ℃ vacuum drying process,active ingredients were in large degree of degradation after drying 2 h,the change of content was small after drying 3 h by comparing with 2 h,general trend was relative stable,the content of active ingredients was less affected in drying process.Sennoside D decomposed easily in heating.Conclusion:During in process of concentration and drying at 70 ℃ vacuum for extraction fluid from R.officinale,concentration time should be controlled within 2 h,components were stable in drying time for 3 h.|
