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
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.

Toxic actions of senaetnine, a new pyrrolizidine-type alkaloid, in rats.[Pubmed:
3660434 ]
Senaetnine is a new type of Senecio alkaloid with a dihydropyrrolizinone structure.
METHODS AND RESULTS:
A limited amount of the crude alkaloid was available for preliminary toxicity tests in weanling male rats via i.p., oral and i.v. routes. Single i.p. or p.o. doses up to 280 mg/kg were not acutely toxic, and showed no evidence of hepatotoxicity. The compound or its metabolites appeared to be eliminated rapidly via the kidneys. However, Senaetnine had a direct irritant action on tissues near to the site of i.p. administration, and caused damage to pulmonary vascular tissue when given i.v. Senaetnine is closely related to, but less reactive than, dehydrosenecionine, a putative short-lived metabolite of the alkaloid senecionine.
CONCLUSIONS:
It possesses mild alkylating reactivity, and the evidence indicates that it can cause moderate tissue injury without the need for metabolic activation. This suggests the need for testing of this and related compounds for chronic toxicity and carcinogenicity.
