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.

Biotransformation of sesquiterpenes by cultured cells ofCurcuma zedoaria[Reference:
WebLink]
METHODS AND RESULTS:
The transformation of a 10-membered ring sesquiterpene, germacrone, into guaiane-type sesquiterpenes by suspension cultured cells ofCurcuma zedoaria was investigated. Germacrone was converted into several sesquiterpenes, some of which were isolated from theCurcuma spp. plants through, the key intermediate, (4R,5R)-germacrone 4,5-epoxide, and their structures were determined by spectral and chemical evidence. The configurations of some of the derivatives were opposite to those of the sesquiterpenes isolated from theCurcuma sp plants,C. aromatica,C. longa andC. zedoaria. An eudesmane-type product was also isolated and its structure was determined. From the structure, the transformation of germacrone through the intermediate, (1S, 10S)-germacrone 1,10-epoxide, was supposed and further confirmed by the transformation of germacrone 1,10-epoxide into the same product by acid treatment.
CONCLUSIONS:
The structures of two new products were also determined and their transformation mechanism through curcumenone and Dihydrocurcumenone was deduced.
