|Solvent:||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.|
|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|After receiving:||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.|

|Antitrypanosomal activities of acetylated bruceines A and C; a structure-activity relationship study.[Pubmed: 21822605 ]|
|The crude extract of Brucea javanica showed strong in vitro inhibitory activity against Trypanosoma evansi. Among the isolated quassinoids, bruceine A, Bruceine C, and bruceantinol were found to be the most potent compounds against T. evansi. To gain a deeper understanding of the relationship between the free hydroxyl groups and the activity, several O-acetylated derivatives of bruceine A and Bruceine C were synthesized and their in vitro antitrypanosomal activities against trypomastigotes of T. evansi were examined and compared with those of the original compounds. The following structure-activity relationships were observed: (1) the free hydroxyl groups at positions C-3, C-11, and C-12 are essential for antitrypanosomal activity; (2) the C-11 and C-12 hydroxyl groups are more important for the activity than the enolic hydroxyl group at C-3, and; (3) the free hydroxyl group at C-4' of Bruceine C does not have any significant effect on the activity.|

|In vitro antitrypanosomal activities of quassinoid compounds from the fruits of a medicinal plant, Brucea javanica.[Pubmed: 18986767 ]|
|The medicinal plant Brucea javanica (L.) Merr. (Simaroubaceae) is widely distributed throughout Asia where its bitter fruits have been used in traditional medicine for various ailments. Fifteen C-20 quassinoids were isolated from the fruits of B. javanica and examined for their in vitro antitrypanosomal activities against trypomastigotes of Trypanosoma evansi. Bruceine A, bruceantinol, Bruceine C, brusatol, and bruceine B showed strong antitrypanosomal activities with IC(50) values in the range of 2.9-17.8nM, which compared well with the standard trypanocidal drugs diminazene aceturate (IC(50)=8.8nM) and suramin (IC(50)=43.2nM). However, dehydrobruceine A, dehydrobruceine B, and dehydrobrusatol were about 2100, 900, and 1200 times less active, respectively, than bruceine A, bruceine B, and brusatol. The relationship of the structure and antitrypanosomal activity of these quassinoid compounds suggested that the presence of a diosphenol moiety in ring A and the nature of the C-15 side chain are important for their activities against T. evansi. This is the first report on the antitrypanosomal activity of isolated quassinoids.|
