Description:

Total phenolic glycosides, fragilin, Picein, salicortin, tremulacin, and tremuloidin all correlated positively with shoot length in glasshouse plants on a carbon-biased balance, and male willows had generally lower levels of phenolic glycosides than females.

Carbon-nutrient balance hypothesis in within-species phytochemical variation ofSalix lasiolepis.[Reference: WebLink]

Predictions of the carbon-nutrient balance hypothesis were tested using a study of within-species phytochemical variation in the arroyo willow,Salix lasiolepis.
METHODS AND RESULTS:
The prediction that a balance between nutrients (total protein) and carbon-based secondary metabolites (total phenols) should exist was supported using water treatment and fertilizer experiments and wild willow clones. Leaf nitrogen content and net photosynthetic rates of plants potted in soil in which parental plants grew was low, indicating that wild plants exist under relatively low nutrient status-high carbon balance conditions. The hypothesis also correctly predicted positive relationships between shoot length and phenols in glasshouse plants, wild plants, and plants in the water treatment experiment and negative relationships between shoot length and phenols in the fertilizer treatment experiment.
CONCLUSIONS:
Total phenolic glycosides, fragilin, Picein, salicortin, tremulacin, and tremuloidin all correlated positively with shoot length in glasshouse plants on a carbon-biased balance, and male willows had generally lower levels of phenolic glycosides than females. Salicortin and tremulacin showed the strongest positive relationships with shoot length.

p‐Hydroxyacetophenone and Picein contents of healthy and damaged spruce needles from different locations in Bavaria.[Reference: WebLink]

METHODS AND RESULTS:
Picein can quickly be converted into p‐hydroxacetophenone by endogenous glucosidases activated by freezing and thawing of spruce needles. Picein was the main component of all investigated spruce needles. Its contents varied between 4 and 30 mg/g fw whereas p‐hydroxyacetophenone (pHAP) concentrations between 0.2 and 0.6 mg/g fw were found. No significant difference for Picein and pHAP contents were observed comparing green and bleached needles or needle segments.
CONCLUSIONS:
In each case the ratio of pHAP to Picein was smaller than one for both green and bleached needles. The importance of pHAP for pigment bleaching is discussed.

Picein Description

Source:	The herbs of Nerium indicum Mill.
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. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. 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.
