| 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. |

Direct quantitative analysis of indicine-N-oxide in cancer patient samples by gas chromatography using the internal standard heliotrine-N-oxide including a mass spectral comparison of their trimethylsilyl derivatives.[Pubmed:7407334]
Biomed Mass Spectrom. 1980 Feb;7(2):65-73.
Indicine-N-oxide was analyzed quantitatively in biological samples using a direct partial purification method involving acetonitrite precipitation or methanol precipitation followed by ion exchange chromatography. Trimethylsilyl derivatization of the resultant provided either of two derivatives, depending on the reaction conditions used, both of which had good gas chromatographic qualities. Heliotrine-N-oxide was used as the internal standard for this work. Data are presented to show that this is a reliable and useful internal standard based on its behavior in the partial purification method and on the gas chromatographic characteristics of its two derivatives. In addition, both low and high resolution mass spectral data indicate that heliotrine-N-oxide produces two trimethylsilyl derivatives analogous to those produced by indicine-N-oxide under the same conditions. Application of this procedure to urine and blood samples from cancer patients in clinical trials indicates that over 95% of the drug is removed from the circulation and excreted in the urine over the course of 48 h.
Pyrrolizidine alkaloids: their occurrence in Spanish honey collected from purple viper's bugloss (Echium spp.).[Pubmed:23886433]
Food Addit Contam Part A Chem Anal Control Expo Risk Assess. 2013;30(10):1799-806.
The incidence and concentration of pyrrolizidine alkaloids (PAs) from Echium spp. plant have been defined in 103 Spanish honey samples. Each sample was examined to determine total pollen content, the percentage of Echium spp. pollen, and simultaneous measurements of PAs and their N-oxides concentrations by the HPLC-ESI/MS method to identify the potential origin of PAs in honey. PAs were found in 94.2% of the raw honey samples analysed, in the range of 1-237 microg kg(-1) (average concentration = 48 microg kg(-1)). The PA pattern was clearly dominated by echimidine, lycopsamine and their N-oxides, representing the 97.8% of total summation operatorPAs, and only echimidine and echimidine-N-oxide surpassed the 87% of total summation operatorPA content. Others PAs, seneciphylline and heliotrine-N-oxide, appear to be reported in a lower incidence and concentration (average of 3 and 1 microg kg(-1), respectively). The Pearson Chi-squared test (p
