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.
Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
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.

Two new protopines argemexicaines A and B and the anti-HIV alkaloid 6-acetonyldihydrochelerythrine from formosan Argemone mexicana.[Pubmed:
12624820]
METHODS AND RESULTS:
Antioxidative activity-guided fractionation together with chemical analysis led to the isolation of three benzophenanthridine alkaloids from methanol extract of the bark of Bocconia arborea. Identification was based on spectroscopic methods. The isolated alkaloids 6-Acetonyldihydrochelerythrine, chelerythrine and dihydrochelerythrine were tested for antioxidative activity on thiocyanate assays, free radical scavenging activity, β β β β β-carotene bleaching method, and deoxyribose assay.
CONCLUSIONS:
All alkaloids exhibited significant antioxidant activities in linoleic acid and β β β β β-carotene. Although afforded protection against the damage of deoxyribose, liposome peroxidation and microsomial lipid from peroxidation, also exhibited scavenging effects on the 1,1-diphenyl-2-picrylhydrazyl radicals.

Three flavones [Desmethoxycentaureidin (10), eupafolin (11), and 6-hydroxyluteolin (12)] from the latter.
METHODS AND RESULTS:
Antiproliferative activity of the isolated compounds against murine melanoma (B16F10), human gastric adenocarcinoma (MK-1), and human uterine carcinoma (HeLa) cells was estimated. (+)-Anymol (3), acteoside (4), isoacteoside (5), arenarioside (8), eupafolin (11), and 6-hydroxyluteolin (12) had GI50 values of 10-16 microM against B16F10 cell.
CONCLUSIONS:
Desmethoxycentaureidin (10) and eupafolin (11) showed high inhibitory activity against HeLa cell growth (GI50 9 microM, and 6 microM, respectively).
