Description: Reference standards.
trans-Methylkhellactone Description
Source: The roots of Peucedanum praeruptorum Dunn.
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 Chalcones from the Aerial Parts of Angelica keiskei.[Reference: WebLink]

METHODS AND RESULTS:
Three new chalcones, 3′‐carboxymethyl‐4,2′‐dihydroxy‐4′‐methoxychalcone (1), (±)‐4,2′,4′‐trihydroxy‐3′‐[(3‐hydroxy‐2,2‐dimethyl‐6‐methylenecyclohexyl)methyl]chalcone (2), and 2′′‐hydroxyangelichalcone (3), were isolated from the aerial parts of Angelica keiskei (Umbelliferae) together with five known compounds, artocarmitin A (4), (+)‐cis‐(3′R,4′R)‐methylkhellactone (5), (−)‐trans‐(3′R,4′S)‐methylkhellactone (trans-Methylkhellactone ,6), 3,4‐dihydroxanthotoxin (7), and (Z)‐p‐coumaryl alcohol (8).
CONCLUSIONS:
The known compounds 4 – 8 were identified from A. keiskei for the first time. The structures of 1 – 3 were elucidated by interpreting spectroscopic data including 1D‐ and 2D‐NMR.
