Cephalocyclidin A Description
Source: The fruits of Cephalotaxus harringtonia var. nana
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.

Cephalocyclidin A, a novel pentacyclic alkaloid from Cephalotaxus harringtonia var. nana.[Pubmed: 11925242]

METHODS AND RESULTS:
A novel alkaloid with an unprecedented fused-pentacyclic skeleton and six-consecutive asymmetric centers, Cephalocyclidin A (1), has been isolated from the fruits of Cephalotaxus harringtonia var. nana, and the structure was elucidated on the basis of spectroscopic data.
CONCLUSIONS:
The relative and absolute stereochemistry of Cephalocyclidin A was determined by a combination of NOESY correlations, X-ray crystallographic data, and the exciton chirality method.
