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.

Interiotherins C and D, two new lignans from Kadsura interior and antitumor-promoting effects of related neolignans on Epstein-Barr virus activation.[Pubmed:
12350139]
METHODS AND RESULTS:
Two new lignans, Interiotherin C (1) and interiotherin D (2), together with the known compounds interiorin (3), heteroclitin F (4), neokadsuranin (5), heteroclitin D (6), kadsurin (7), gomisin A (8), schisandrin C (9), interiotherin A (10), angeloylgomisin R (11), gomisin G (12), interiotherin B (13), and gomisin C (14), were isolated from the stems of Kadsura interior. The structures and stereochemistries of the new compounds were determined from mass, CD, and NMR spectral data. Fourteen neolignans were screened as potential antitumor promoters by examining their ability to inhibit Epstein-Barr virus early antigen (EBV-EA) activation (induced by 12-O-tetradecanoylphorbol-13-acetate) in Raji cells.
CONCLUSIONS:
Neokadsuranin (5) and schisandrin C (9) were the most potent compounds. These data suggest that some neolignans might be valuable antitumor promoters or chemopreventors.

Kadsutherin D, a new dibenzocyclooctadiene lignan from Kadsura species[Pubmed:
19023792]
METHODS AND RESULTS:
A new dibenzocyclooctadiene lignan, kadsutherin D (1), together with 12 known lignans, kadsurin (2), heteroclitin C (3), Interiotherin C (4), schisanlignone A (5), binankadsurin A (6), angeloyl binankadsurin A (7), gomisin U (8), heteroclitin D (9), interiorin (10), schiarisanrin C (11), heteroclitin G (12) and meso-dihydroguaiaretic acid (13) were isolated from the stems of Kadsura species.
CONCLUSIONS:
Their structures were elucidated by spectroscopic methods including 2D-NMR techniques.
