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.

Biological Activity of Betulin caffeate

DescriptionBetulin-3β-caffeate shows moderate antioxidant activity with IC50 value 108.0 ug/ml.
In vitro

Secondary metabolites (Triterpenes) from Couroupita guianensi[Reference: WebLink]

Oriental Pharmacy and Experimental Medicine, 2009 9(2), 200-205.


METHODS AND RESULTS:
The n-hexane and carbon tetrachloride soluble fractions of a methanolic extract of the stem bark of the Couroupita guianensis furnished three compounds, identified as β-amyrin (1), betulin-3β- caffeate (Betulin caffeate,2) and lupeol-3β-caffeate (3). The structures of the isolated compounds were deduced by extensive spectroscopic analysis as well as by comparison with published values.
CONCLUSIONS:
Compounds 1-3 were subjected to antioxidant screening through free radical scavenging activity by DPPH (1,1- diphenyl-2-picrylhydrazyl), where compound 2 showed moderate antioxidant activity with IC50 value 108.0 μg/ml

Chemistry of Natural Compounds, 1987 , 23 (4) :513-514.

Isoprenoids of the outer bark of the Far Eastern birches Betula costata and Betula ermanii[Reference: WebLink]


METHODS AND RESULTS:
(4), the acetate of oleanolic acid (III), lupeol (IV), methyl oleanolate (V), betulin (VI), bet- ulinic acid (VII), oleanolic (VIII), and Betulin caffeate (IX). Compounds (VI-IX) were iso- lated after the acetylation of the fraction containing a difficultly separable mixture of these components. Extracts of the bark of B. costata and B. ermanii (samples 2 and 5) showed antioxidant activity according to the method of Maximov et al. (5).
CONCLUSIONS:
The activity of these samples is obviously connected with the presence of Betulin caffeate (6), since this component was pres- ent only in summer samples of the bark. The results of the investigation are given in Table i. The structures of the compounds isolated were confirmed by mixed melting points with authen- tic samples (no depression of the melting points was observed) and by comparison of their !R spectra.
