Description:

Dibritannilactone B is a natural product from Inula britannica.

In vitro:

Rsc Advances, 2015, 46(22):1979-1982.

One new unusual sesterterpenoid and four new sesquiterpene dimers from Inula britannica.[Reference: WebLink]

METHODS AND RESULTS:
One new unusual sesterterpenoid (Dibritannilactone A,1), four new sesquiterpene dimers (Dibritannilactone B, Dibritannilactone C, Dibritannilactone D, Dibritannilactone E,2–5) together with nine known sesquiterpenes (6–14) were isolated from the aerial parts of Inula britannica.
CONCLUSIONS:
The structures of the new compounds were elucidated by detailed spectroscopic analysis, including HR-ESIMS and 2D-NMR spectroscopic methods. In addition, compounds 1–8 and 10–11 were tested for their inhibitory effects against LPS-induced NO production in RAW264.7 macrophages.

Dibritannilactone B Description

Source:	The aerial parts of Inula britannica.
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.
