| 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. |

[Biotransformation of phenolglycosides leiocarposide and salicin].[Pubmed:2594827]
Pharmazie. 1989 Aug;44(8):555-8.
Leiocarposide (1; 3-beta-D-glucopyranosyloxy-2-methoxy-6-hydroxy-benzoic acid -2'-beta-D-glucopyranosyloxybenzyl ester) is a phenolic glycoside from Solidago virgaurea L. After oral administration to rats it will be only poorly absorbed and mostly unchanged fecaly excreted. In the urine were found less than 10% as metabolites: leiocarpic acid (3; 3,6-dihydroxy-2-methoxy-benzoic acid, 2% of the administered dose), 3-conjugates (2%), salicylic acid (5; 0.5%), 5-conjugates (0.1%) and salicyluric acid (6; 0.5%). On the other hand salicin (2), structural part of 1, is good absorbed. In the urine were excreted 15% of the unchanged drug and the following metabolites: 0.1% saligenin (4), 30% 5, 5% 5-conjugates, 0.1% 6, 2% gentisic acid (7) and 0.1% 2,3-dihydroxy-benzoic acid (8). The different metabolic rates are explicable by the high stability of the ester bond of 1. It is hydrolyzed in artificial intestinal fluid only very slowly (t1/2 = 41.7 h).
