General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.

Nitrogen compounds in Phacelia tanacetifolia Benth. honey: First time report on occurrence of (-)-5-epi-lithospermoside, uridine, adenine and xanthine in honey.[Reference: WebLink]


METHODS AND RESULTS:
Lacy phacelia (Phacelia tanacetifolia Borkh.) honey composition was screened by UHPLC-DAD-QqTOF-MS. The targeted analysis revealed 6 major nitrogen compounds including aromatic amino acids (tyrosine, phenylalanine), purine derivatives (adenine, xanthine), nucleoside (uridine) and rare non-cyanogenic cyanoglucoside, (-)-5-epi-lithospermoside ((2Z)-2-[(4R,5R,6S)-4,5-dihydroxy-6-(β-d-glucopyranosyl)oxycyclohex-2-en-1-ylidene]acetonitrile). Their identity was confirmed by different analytical tools: HRMS, co-chromatography with standard compound or comprehensive NMR experiments. All the compounds, except amino acids, were reported and determined in honey for the first time. The amount of the compounds was quantified in 16 unifloral phacelia samples: adenine (18.45 ± 4.63 mg/kg), xanthine (10.53 ± 2.98 mg/kg), uridine (42.84 ± 9.26 mg/kg), tyrosine (14.66 ± 10.22 mg/kg), (-)-5-epi-lithospermoside (70.61 ± 31.37 mg/kg) and phenylalanine (20.41 ± 11.99 mg/kg).
CONCLUSIONS:
The (-)-5-Epilithospermoside content is significantly correlated with P. tanacetifolia pollen percentage (R2 = 0.5612, p < 0.001) and it is proposed as a potential marker of botanical origin for phacelia honey.
