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.

Four new stilbenoids from the lianas of Gnetum montanum f. megalocarpum.[Pubmed: 14994195]


METHODS AND RESULTS:
From the lianas of Gnetum montanum Markgr. f. megalocarpum Markgr., four new stilbenoids, gnetumontanins A - D ( 1 - 4) were obtained together with 16 known compounds. Gnetumontanin A ( 1) is the first oligostilbene dimerized from two oxyresveratrol units, Gnetumontanin B ( 2) is a new stilbene trimer oligomerized from two oxyresveratrol and one resveratrol units, gnetumontanin C ( 3) is a new stilbenoid with a novel skeleton having a delta-lactone moiety and gnetumontanin D ( 4) is a glucoside of 3. Their structures were determined by means of spectroscopic evidence, especially 2D NMR techniques.
CONCLUSIONS:
Gnetumontanin B showed potent inhibition of TNF-alpha with an inhibitory ratio of 58.1 % (P < 0.05) at a concentration of 10 ( - 5) mol L (-1) and the IC (50) was 1.49 x 10 ( - 6) mol L (-1).
