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.

Hepatotoxic pyrrolizidine alkaloids in Emilia sonchifolia from Taiwan[Reference: WebLink]

Emilia sonchifolia (L.) DC. (Lilac tasselflower, Zi Bei Cao) is used in Asian countries for food or medicinal purposes. We have investigated the hepatotoxic pyrrolizidine alkaloids (PAs) contained in E. sonchifolia. The objective was to determine profile and quantity of the PAs in E. sonchifolia samples that were collected from several towns in Taiwan.
METHODS AND RESULTS:
Pyrrolizidine alkaloids were isolated and purified from the aqueous acid extracts by use of strong cation exchange-solid phase extraction (SCX-SPE). Alkaloid extracts were analyzed using gas–chromatography mass spectrometry (GC–MS). Eleven PAs of two types were identified in E. sonchifolia (by type): (1) retronecine bases, senecionine, seneciphylline and integerrimine; (2) otonecine bases, senkirkine, otosenine, Neosenkirkine, petasitenine, acetylsenkirkine, desacetyldoronine, acetylpetasitenine, and doronine. Quantification of the individual PAs was determined by six-point linear regression curves in the range of 25–400 μg/mL of senkirkine and senecionine. The PAs were found in all plant organs of E. sonchifolia. Senkirkine was the major PA identified with concentrations up to 53.8 μg/g of dry herb. The average total PA concentration varied from a low of 33.3 μg/g to a high of 93.9 μg/g dry herb.
CONCLUSIONS:
This study will provide important information to public consumers regarding the health risk of PA-containing E. sonchifolia.
