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.

2beta-(Isobutyryloxy)florilenalin, a sesquiterpene lactone isolated from the medicinal plant Centipeda minima, induces apoptosis in human nasopharyngeal carcinoma CNE cells.[Pubmed:
19553887]
Centipeda minima is a medicinal plant reputed in China as a remedy for nasopharyngeal carcinoma (NPC).
METHODS AND RESULTS:
In this study, bioactivity-guided fractionation of the anti-NPC compound(s) from C. minima led to the isolation of 2beta-(Isobutyryloxy)florilenalin (IF), a sesquiterpene lactone. IF showed significant dose- and time- dependent inhibition on the growth of the human nasopharyngeal carcinoma epithelia cells (CNE). It induced apoptosis in CNE cells, as shown by the accumulation of sub-G1 cell population, DNA fragmentation and nuclear condensation, caspase-3 activation and PARP cleavage. Such induction was associated with the depletion of mitochondrial membrane potential (DeltaPsim) and the release of cytochrome c to cytosol to regulate the expression of Bcl-2 family proteins.
These activities led to the cleavage of caspases and the trigger of cell death process.
CONCLUSIONS:
Overall, IF in C. minima showed potent antiproliferative effect of C. minima on NPC cells, suggesting that the plant deserves more extensive investigation for its potential medicinal application.
