| 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. |

The isolation and structural elucidation of eupaserrin and deacetyleupaserrin, new antileukemic sesquiterpene lactones from Eupatorium semiserratum
J Org Chem. 1973 Apr 6;38(7):1260-4.
Evidence is presented for the assignment of structures for eupaserrin (1) and Deacetyleupaserrin (5), two antileukemic sesquiterpene lactones from Eupatorium semiserratum DC. Elemental analysis and high resolution mass spectrometry supported a C22H28O7 molecular formula for eupaserrin (1) and a C20H26O6 molecular formula for Deacetyleupaserrin (5). Acetylation of 5 gave 1 and acetyleupaserrin (2), whereas alkaline hydrolysis of 5 gave sarracinic acid. Chemical and spectral evidence indicated the presence of α-methylene-γ-lactone, α,β-unsaturated ester, secondary hydroxyl, and two vinyl methyl groupings in 1 and 5 and suggested that both 1 and 5 were germacranolide dienes. Pyrolysis of 5 gave an oily aldehyde lactone (6), and pyrolysis of 2 gave an enol acetate (3). Chemical and spectral arguments are advanced for assignment of structure and stereochemistry for 2 and 3 and therefore 1 and 5.
