A high-pressure liquid chromatography-diode array detection and
multi-mode ionization tandem mass spectrometry (HPLC-DAD-MMI-MS/MS)
method was used to identify amino-tadalafil and rimonabant in electronic
cigarette (e-cigarette) cartridges. Amino-tadalafil is a drug analogue
of the commercially approved ™ (i.e. tadalafil). Rimonabant is a drug
that was, at one time, approved for weight loss in Europe (although
approval has been retracted), but not in the United States. In addition,
poor quality control over the e-cigarette products analyzed here is
shown by the presence of nicotine in products labeled as containing no
nicotine or by the presence of significant amounts of rimonabant
oxidative degradant in e-cigarette products containing rimonabant.
Identification was accomplished by comparing the retention time of
relevant peaks in the sample with those of standard compounds, in
addition to comparison of the UV spectra, mass spectra and/or product
ion mass spectra.buyaas Tadalafil powder
Function:
Made of natural soybean oil residue extraction. Is the cell membrane
of the active material, especially exists in the brain cells.
The main function is to improve the function of nerve cells, adjust
the transmission of nerve impulses, enhance memory function, due to its
strong lipotropy, absorbed quickly through the blood brain barrier into
the brain, help relax vascular smooth muscle cells, increase the role of
brain blood flow.
