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.

Aryloxyacetamides Derived from Resveratroloside and Pinostilbenoside[Reference: WebLink]


METHODS AND RESULTS:
Etherification of phenolic hydroxyl groups of resveratroloside and Pinostilbenoside (natural 3,4’,5-trihydroxystilbene derivatives) with methyl bromoacetate afforded compounds ArOCH2CO2Me, which on treatment with amines produce the corresponding ‘stilbenyl- oxyacetamides’ in good yields.

Reaction of several resveratrol glycoside derivatives with hypochlorites in various media[Reference: WebLink]


METHODS AND RESULTS:
The reactions of pterostilbenoside (trans-3,5-dimethoxystilben-4′-O-β-D-glucoside) and Ar–O–Tr derivatives of resveratroloside (3,5-dihydroxystilben-4′-O-β-D-glucoside) and Pinostilbenoside (3-methoxy-5-hydroxystilben-4′-O-β-D-glucoside) with NaOCl and t-BuOCl in the presence of the stable nitroxyl radical TEMPO were studied in various media. It was found that the principal product of pterostilbenoside transformation was its 2,6-dichloroderivative, a part of which was oxidized to form 2,6-dichloropterostilbene glucuronide.
CONCLUSIONS:
Trityl ethers of resveratroloside and Pinostilbenoside reacted with the hypochlorites to form mixtures of products.

Hydroxystilbenes of the inner bark of Pinus sibirica[Reference: WebLink]


METHODS AND RESULTS:
In addition to pinostilbene and resveratrol, two new stilbene glycosides have been isolated from the phloem ofPinus sibirica R. Mayr, and their structures have been established as 3,4′-dihydroxy-5-methoxy-stilbene 4′-β-D-glycopyranoside (Pinostilbenoside) and 3,4′,5-trihydroxystilbene 4′-β-D-glycopyranoside (resveratroloside).
