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.

Anti-inflammatory triterpenes from the apical bud of Gardenia sootepensis.[Pubmed:
27575322]
Bioassay-guided fractionation of the dichloromethane extract from the apical bud of Gardenia sootepenesis Hutch. (Rubiaceae) led to the isolation of four new cycloartane triterpenes, sootepins F-I (1-4), along with four known derivatives (5-8).
METHODS AND RESULTS:
The structures of the new compounds were determined by 1D and 2D NMR experiments and by comparison of the physicochemical data with published values. The isolates were evaluated for cancer chemopreventive potential based on their ability to inhibit nitric oxide (NO) production and tumor necrosis factor-alpha (TNF-α)-induced nuclear factor kappa (NF-κB) activity.
CONCLUSIONS:
Compounds 6-8 inhibited TNF-α-induced NF-κB activity with half maximal inhibitory concentration (IC50) values of 8.3, 5.6, and 6.0μM, respectively; compounds 7 and 8 showed significant NO-inhibitory activity with IC50 values of 3.2 and 2.0μM, respectively.
