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.

Investigations on anthrachinonglycosides of Rhamnus species, V Emodin-8-O-beta-gentiobiosid,e a new O-glycoside from Rhamnus frangula[Reference: WebLink]


METHODS AND RESULTS:
From the bark of Rhamnus frangula a new glycoside has been isolated and its structure elucidated as Emodin-8-O-beta-gentiobioside. The structure was confirmed by glycosidation of 6–O–benzoyl–emodin with α–acetobromgentiobiose in a Koenigs–Knorr reaction followed by saponification.
