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.

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.

TLC-SERS Study on Evodiamine in Evodia Rutaecarpa[Reference:
WebLink]
METHODS AND RESULTS:
A new method for analyzing the ingredients of evodiamine(EV), rutaecarpine(RU), Hydroxyevodiamine(HYD), evodiamide(ED), dihydrorutaecarpine(DRU) and 14-formyldihydrorutaecarpine(FDRU)in evodia rutaecarpa using high performance thin layer chromatography (TLC) and surface enhanced Raman spectroscopy (SERS) technique is reported. The character of this method is that standard samples are not needed . The results show that the characteristic spectral bands of EV, RU, Hydroxyevodiamine, and ED can be obtained from the TLC spot with microgramme of sample. The spectral band at 1 562 cm-1 was obtained with great enhancement. Molecule absorbed in surface silver sol by π electrons in ring.
CONCLUSIONS:
The spectral bands of EV, RU, Hydroxyevodiamine and ED are obviously different due to their differences in structure.
