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.

    Neolignans, a coumarinolignan, lignan derivatives, and a chromene: anti-inflammatory constituents from Zanthoxylum avicennae.[Pubmed: 18211005 ]

    METHODS AND RESULTS:
    Eight new compounds, including four new neolignans, (7' S,8' S)-bilagrewin ( 1), (7' S,8' S)-5-demethoxybilagrewin ( 2), (7' S,8' S)-5- O-demethyl-4'- O-methylbilagrewin ( 3), and (7' S,8' S)-nocomtal ( 4), a new coumarinolignan, (7' S,8' S)-4'- O-methylcleomiscosin D ( 5), two new lignan derivatives, (+)-9'- O-( Z)-feruloyl-5,5'-dimethoxylariciresinol ( 6) and (+)-9'- O-( E)-feruloyl-5,5'-dimethoxylariciresinol ( 7), and a new chromene, ( E)-3-(2,2-dimethyl-2 H-chromen-6-yl)prop-2-enal ( 8), have been isolated from the stem wood of Zanthoxylum avicennae, together with 18 known compounds ( 9- 26). The structures of these new compounds were determined through spectroscopic and MS analyses.
    CONCLUSIONS:
    (7' S,8' S)-4'- O-Methylcleomiscosin D ( 5), cleomiscosin D ( 9), skimmianine ( 18), Robustine ( 19), and integrifoliolin ( 23) exhibited inhibition (IC 50 < or = 18.19 microM) of superoxide anion generation by human neutrophils in response to formyl- l-methionyl- l-leucyl- l-phenylalanine/cytochalasin B (FMLP/CB). In addition, skimmianine ( 18) inhibited FMLP/CB-induced elastase release with an IC 50 value of 19.15 +/- 0.66 microM.

    Inhibitory effects of furoquinoline alkaloids from Melicope confusa and Dictamnus albus against human phosphodiesterase 5 (hPDE5A) in vitro.[Pubmed: 16042076]
    Eight furoquinoline alkaloids were purified from two plants belonging to the Rutaceae family. Kokusaginine, skimmianine, evolitrine, and confusameline were purified from Melicope confusa, and haplopine, Robustine, dictamine, and gamma-fagarine from Dictamnus albus.
    METHODS AND RESULTS:
    In this study, the eight furoquinoline alkaloids were examined for inhibitory potency against human phosphodiesterase 5 (hPDE5A) in vitro. DNA encoding the catalytic domain of human PDE5A was amplified from the mRNA of T24 cells by RT-PCR and was fused to GST in an expression vector. GST-tagged PDE5A was then purified by glutathione affinity chromatography and used in inhibition assays. Of the eight alkaloids, gamma-fagarine was the most potent inhibitor of PDE5A, and its single methoxy group at the C-8 position was shown to be critical for inhibitory activity.
    CONCLUSIONS:
    These results clearly illustrate the relationship between PDE5A inhibition and the methoxy group position in furoquinoline alkaloids.
