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.

A novel ent-kaurane diterpenoid from Pterís semipinnata.[Reference: WebLink]

METHODS AND RESULTS:
The chemical investigation of the aerial parts of Pteris semipinnata furnished a novel ent-kaurane diterpenoid, and three known sesquiterpenoids with a 1-indanone skeleton, namely (2R)-pterosin B, (2S, 3S)-pterosin C and norpterosin C(trans-Norpterosin C).
CONCLUSIONS:
The structure of 7β-hydroxy-11β, 16β-epoxy-ent-kauran-19-oic acid was established by spectroscopic methods, especially two dimensional NMR techniques.
