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.

Phenolic compounds from the stem bark of Erythrina orientalis and their cytotoxic and antioxidant activities[Reference:
WebLink]
METHODS AND RESULTS:
Two prenylated pterocarpans, phaseollin (1), shinpterocarpin (2) together with flavonoids, 4'-O-Methyllicoflavanone (3), alpinumisoflavone (4), 8-prenyl-daidzein (5), have been isolated from the stem bark of Erythrina orientalis. The structures of these compounds were determined based on UV, IR, HRESIMS, 1D and 2D NMR data.
CONCLUSIONS:
Compounds 1–5 were evaluated for their cytotoxic properties against P-388 cells, their IC 50 values 2.55, 2.43, 17.98, 4.31, and 5.82 μg/mL, respectively. Compounds 1, and 5 exhibited very high antioxidant activity against DPPH radical scavenging.
