| 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. |

Application of high-speed counter-current chromatography for preparative separation of cyclic peptides from Vaccaria segetalis.[Pubmed:21396894]
J Chromatogr B Analyt Technol Biomed Life Sci. 2011 Apr 1;879(11-12):811-4.
Following an initial clean-up step on silica gel, high-speed counter-current chromatography (HSCCC) was used to separate cyclic peptides from an extract of the seeds of Vaccaria segetalis. The two-phase solvent system used for HSCCC separation was composed of petroleum ether-ethyl acetate-methanol-water at an optimized volume ratio of 0.5:3.5:1:5. From 190 mg of crude extract, 38.0 mg of Segetalin B and 28.5 mg of segetalin A were obtained with purities of 98.1% and 95.6% as determined by HPLC, respectively. The chemical structures of the target compounds were confirmed by high resolution electrospray ionization time of flight MS (HRESI-TOF-MS) and (1)H NMR analyses.
Thionation of segetalins A and B, cyclic peptides with estrogen-like activity from seeds of Vaccaria segetalis.[Pubmed:9113340]
Bioorg Med Chem. 1997 Mar;5(3):631-6.
Thionation of estrogen-like active cyclic peptides, segetalins A (1) and B (2), with Lawesson's reagent provided each two thiosegetalins; thiosegetalin A1 [Gly-1-psi(CS-NH)-Val-2; Trp-5-psi (CS-NH)-Ala-6]segetalin A, thiosegetalin A2 [Gly-1-psi(CS-NH)-Val-2; Ala-6-psi(CS-NH)-Gly-1]segetalin A, thioSegetalin B1 [Gly-1-psi (CS-NH)-Val-2; Ala-3-psi(CS-NH)-Trp-4]Segetalin B, and thioSegetalin B2 [Gly-1-psi(CS-NH)-Val-2; Trp-4-psi(CS-NH)-Ala-1]Segetalin B. Thiosegetalin A2 only showed estrogen-like activity against ovariectomized rats. On the basis of their conformations analysed by NMR experiments, the backbone conformation was considered to play an important role in estrogen-like activity for segetalins.
