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.

Chemical Components of Alkaloids from Euodiae Fructus and Their Anti-angiogenic Activities[Reference: WebLink
To study the chemical constituents and their anti-angiogenic activities of the fruits of Evodia rutaecarpa.
METHODS AND RESULTS:
Compounds were isolated and purified by column chromatography using silica gel,Sephadex LH-20, ODS and semi-preparative HPLC. Their structures were identified on the basis of physicochemical properties and spectral data. The anti-angiogenic activities of compounds were evaluated using a zebrafish model. Result: Twenty compounds were isolated and identified from the fruits of E. rutaecarpa,including one degraded limonoids calodendrolide( 1),6 indole alkaloids,i. e. rutaecarpine( 2),evodiamine( 3),goshuyuamide-Ι( 4),N-formyldihydrorutaecarpine( 5),and 7beta-Hydroxyrutaecarpine( 6),11 quinolone alkaloids,i. e. 2-hydroxy-4-methoxy-3-( 3'-methyl-2'-butenyl)-quinoline( 7),1-methyl-2-nonyl-4( 1H)-quinolone( 8),1-methyl-2-decyl-4( 1H)-quinolone( 9),1-methyl-2-undecyl-4( 1H)-quinolone( 10),dihydroevocarpine( 11),1-methyl-2-pentadecenyl-4( 1H)-quinolone( 12),1-methyl-2- [( Z)-6-undecyl]-4( 1H)-quinolone( 13),evocarpine( 14),1-methyl-2- [( Z)-4-tridecyl]-4( 1H)-quinolone( 15),mixture of 1-methyl-2- [( Z)-10-pentadecenyl ]-4( 1H)-quinolone and 1-methyl-2- [( Z)-6-pentadecenyl]-4( 1H)-quinolone( 16),1-methyl-2- [( 6Z,9Z)-6,9-pentadecenyl]-4( 1H)-quinolone( 17),2 amides,i. e. N-methylanthranylamide( 18),acetamide( 19),and one sterol,i. e. β-sitosterol( 20).Compounds 1( 20 mg·L~(-1)),2( 0. 5 mg·L~(-1)),3( 5,10 μg·L~(-1)),4( 10 mg·L~(-1)),5( 50 mg·L~(-1)),10( 20 mg·L~(-1)),11( 50 mg·L~(-1)),16( 20 mg·L~(-1)),and 18( 50 mg·L~(-1)) showed anti-angiogenic effects on internode blood vessels of Zebrafish models.
Compounds 1-18 were characteristic constituents of Euodiae Fructus,and compounds 1 and 7 were isolated from this plant for the first time. Compounds 1-5,10,11,16,and 18 showed anti-angiogenic effects on internode blood vessels of Zebrafish models.
