Biological Activity
Description: Norpterosin B is a natural product from Pteris semipinnata.
Norpterosin B Description
Source: The aerial parts of Pteris semipinnata.
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: 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).

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
After receiving: 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.

Three New Illudalane Sequiterpenoids from Pteris semipinnata.[Reference: WebLink]

METHODS AND RESULTS:
The chemical investigation of the aerial parts of Pteris semipinnata resulted in the isolation of three illudalane sesquiterpenoids, namely (2R)-Norpterosin B (1), (2R)-12-O-β-D-glucopyranosylNorpterosin B (2), and semipterosin A (3), along with three known compounds.
CONCLUSIONS:
The structures of 1–3 were established by spectroscopic methods, including extensive 2D-NMR and CD analyses.
