Description:

Highest concentrations of (2R,3R)-(+)-glucodistylin, (2S,3S)-(-)-glucodistylin and 3-O-( -d-xylopyranosyl)taxifolin occur in European beeches can strongly infest with beech scale.

Phenols from Fagus sylvatica and their role in defence against Cryptococcus fagisuga.[Reference: WebLink]

METHODS AND RESULTS:
In extracts of inner and outer bark of Fagus sylvatica, qualitative dependence of the phenolic composition on infection with Cryptococcus fagisuga feeding in the parenchyma tissue was observed. The seven major compounds were isolated and completely assigned, mainly by two-dimensional NMR techniques. Highest concentrations of (2R,3R)-(+)-glucodistylin, (2S,3S)-(-)-Glucodistylin and 3-O-( -d-xylopyranosyl)taxifolin occur in European beeches strongly infested with beech scale.
CONCLUSIONS:
The concentration of cis-coniferin was lowered after attack, while the concentrations of catechin, cis-isoconiferin and cis-syringin remained unaffected. The changes are discussed as a defence reaction.

(2S,3S)-(-)-Glucodistylin Description

Source:	The herbs of Agrimonia pilosa
Solvent:	DMSO, Pyridine, Methanol, Ethanol, 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.
