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.

Structures of new beta-carboline-type alkaloids with antiallergic effects from Stellaria dichotoma(1,2).[Pubmed: 21090796 ]

The aqueous ethanolic extract from the roots of Stellaria dichotoma showed an antiallergic effect on ear passive cutaneous anaphylaxis (PCA) reaction in mice (in vivo) and inhibitory activity on the release of beta-hexosaminidase in RBL-2H3 cells (in vitro).
METHODS AND RESULTS:
From the aqueous ethanolic extract, new beta-carboline-type alkaloids, dichotomine A (1), Dichotomine B (2), dichotomine C (3), and dichotomine D (4) and dichotomides I (5) and II (6), were isolated. The structures of the new constituents (1-6) were determined on the basis of chemical and physicochemical evidence, including the application of the modified Mosher's method.
CONCLUSIONS:
The effects of the isolated constituents on the release of beta-hexosaminidase in RBL-2H3 cells were examined, and 3 was found to show inhibitory activity (IC(50) = 62 microM). Moreover, 3 also inhibited the releases of antigen-IgE-mediated TNF-alpha and IL-4 (19 and 15 microM, respectively) in RBL-2H3 cells, both of which participate in the late phase of type I allergic reactions.
