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.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Comparative HILIC/ESI-QTOF-MS and HPTLC studies of pyrrolizidine alkaloids in flowers of Tussilago farfara and roots of Arnebia euchroma.[Reference: WebLink]

The utility of HPTLC and HILIC/ESI-QTOF-MS for the determination of pyrrolizidine alkaloids (PAs) and their N-oxides (PANOs) was compared in the selected plant species: Tussilago farfara L. (TF, flower) and Arnebia euchroma (Royle) I.M. Johnst. (AE, root). HPTLC confirmed the postulated presence of PAs (saturated and unsaturated) or PANOs in the tested extracts.
METHODS AND RESULTS:
In accordance with previous studies, HILIC/ESI-Q-TOF-MS confirmed the presence of the toxic PA senkirkine and the saturated otonecine-type PAs, tussilagine and isotussilagine in the TF extract and 7-angeloylretronecine and 9-angeloylretronecine in AE extract. Moreover, the following alkaloids were identified in AE root: intermedine, intermedine-N-oxide, leptanthine-N-oxide, echimidine-N-oxide (or their corresponding stereoisomers) and traces of 7-angeloylretronecine and 9-Angeloylretronecine N-oxide.
CONCLUSIONS:
The study demonstrates the HILIC/ESI-Q-TOF-MS method to be a very useful tool for monitoring PAs and PANOs in the test samples, even when not all of the necessary standards are available. Quantitative analysis of senkirkine in TF flower by HILIC/ESI-QTOF-MS featured high resolution, high precision, high mass accuracy, and very high sensitivity with limit-of-detection (LOD) of 27.50 fg/μL and limit-of-quantitation (LOQ) of 91.60 fg/μL. The results from both methods may be used for the development or rejection of European Pharmacopoeia (X) monographs of both investigated species.
