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.

Limonoid constituents of Euodia rutaecarpa var. bodinieri and their inhibition on NO production in lipopolysaccharide-activated RAW264.7 macrophages.[Pubmed:
23869424 ]
METHODS AND RESULTS:
A new limonoid compound, named evorubodinin (1), was isolated from the dried and nearly ripe fruits of Euodia rutaecarpa (Juss.) Benth. var. bodinieri (Dode) Huang (family Rutaceae), together with two known limonoid compounds, limonin (2) and evolimorutanin (3). The chemical structure of 1 was elucidated by spectroscopic method and single-crystal X-ray diffraction. The inhibitory effects of the isolated compounds 1-3 and the structurally related compounds evodol (4), shihulimonin A1 (5), evodirutaenin (6), 12α-hydroxyRutaevin (7), and Rutaevin (8) on nitric oxide (NO) production in lipopolysaccharide-activated RAW264.7 macrophages were also assayed.
CONCLUSIONS:
All compounds 1-8 showed the inhibitory activity, in which both 7 and 8 with the uncommon 5β-H configuration more efficiently inhibited NO production. The results provided valuable information for further investigation of compounds 1-8 as anti-inflammatory agents or lead compounds.

Pyranochromones from Dictyoloma vandellianum A. Juss and Their Cytotoxic Evaluation.[Pubmed:
27797447 ]
METHODS AND RESULTS:
One new chromone 3,3-dimethylallylspatheliachromene methyl ether (1), as well as five known chromones, 6-(3-methylbut-2-enyl) allopteroxylin methyl ether (2), 6-(3-methylbut-2-enyl) allopteroxylin (3), 3,3-dimethylallylspatheliachromene (4), 5-O-methylcneorumchromone K (5) and spatheliabischromene (6), two alkaloids, 8-methoxy-N-methylflindersine (7) and 8-methoxyflindersine (8), and two limonoids, limonin diosphenol (9) and Rutaevin (10), were isolated from Dictyoloma vandellianum A. Juss (Rutaceae). Cytotoxic activities towards tumor cell lines B16-F10, HepG2, K562 and HL60 and non-tumor cells PBMC were evaluated for compounds 1 - 6.
CONCLUSIONS:
Compound 1 was the most active showing IC50 values ranging from 6.26 to 14.82 μg/ml in B16-F10 and K562 cell lines, respectively, and presented IC50 value of 11.65 μg/ml in PBMC cell line.
