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.

Monophyllidin, a new alkaloid L-proline derivative from Zanthoxylum monophyllum[Reference:
WebLink]
METHODS AND RESULTS:
A new L-proline derivative, monophyllidin (1), together with four known compounds, Thalifoline (2), berberine (3), jathrorrhizine (4) and 3β-glucositosterol (5) has been isolated from the bark of Zanthoxylum monophyllum. The structure of compound 1 was elucidated on the basis of extensive spectroscopic data analysis. Characterization of compounds 2–5 was based on spectral analysis and comparison with reported data.
CONCLUSIONS:
Compound 3 showed antibacterial activity against the five bacterial strains used, while 1, 4 and 5 presented only antibacterial activity against Enterococcus faecalis. Compounds 2 and 4 showed antifungal activity, with 100 μg against Fusarium oxysporum f. sp. lycopersici.

Alkaloids of Cryptocarya longifolia: X-Ray Crystal Structure of Thalifoline and Longifolonine.[Reference:
WebLink]
METHODS AND RESULTS:
The known alkaloids reticuline (1), coclaurine (3), N-methylcoclaurine (2), laurotetanine (7), N-methyl-laurotetanine (8), laurolitsine (10), isoboldine (9), norisocorydine (6), norargemonine (ll), bisnorargemonine (12), Thalifoline (16) and scoulerine (13) were isolated from the New Caledonian plant Cryptocarya longifolia together with two new bases, longifolidine (4) and longifolonine (14).
CONCLUSIONS:
Spectroscopic methods were used for identification and structural investigation, and X-ray crystallographic analysis to determine the structures of Thalifoline and longifolonine.
