Six new diarylheptanoids from the seeds of Alpinia blepharocalyx.[Reference: WebLink]

METHODS AND RESULTS:
Chromatographic separation of part of an EtOH extract of the seeds of Alpinia blepharocalyx resulted in the isolation of six new (1-6) and two known (7, 8) diarylheptanoids together with 12 known compounds. The structures of the new compounds, including their absolute stereochemistry, were elucidated by spectroscopic and chemical methods as (3S,5S)- (1) and (3S,5R)-3-hydroxy-5-methoxy-1-(4-hydroxyphenyl)-7-phenyl-6E-heptene (2), (3S,5S)- (3) and (3S,5R)-3-hydroxy-5-ethoxy-1-(4-hydroxyphenyl)-7-phenyl-6E-heptene (4), (3S)-methoxy-1,7-bis(4-hydroxyphenyl)-6E-hepten-5-one (5), and 1,7-bis(4-hydroxyphenyl)hepta-4E,6E-dien-3-one (6).
CONCLUSIONS:
Among the isolated compounds, 5, (3S,5S)-3,5-dihydroxy-1,7-bis(4-hydroxyphenyl)heptane (8), 4'-hydroxy-5,6-dehydrokawain (p-Hydroxy-5,6-dehydrokawain,14), and/or phloroglucinol (20) showed significant antiproliferative activity against murine colon 26-L5 carcinoma (ED(50): 5, 5.2 microM; 8, 12.8 microM; 14, 20.7 microM; 20, 26.4 microM) and human HT-1080 fibrosarcoma (ED(50): 5, 10.1 microM; 14, 20.1 microM; 20, 20.9 microM) cells.

Source: The roots of Piper methysticum Forst
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).

Wherever possible, you should prepare and use solutions on the same day.

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.
