ESI-MS analysis of the synthesized compounds, performed as reported above, confirmed the expected regioisomerism for every pure diamino--CD, since the fragment per- centages calculated from the spectra corresponded with those previously obtained. It should be noted that the striking similarity be...
Generally, in the present study, a sensitive and accurate strategy was developed for the comprehensive chemi- cal analysis of Maca firstly. UHPLC-ESI-Orbitrap MS and UHPLC-ESI-QqQ MS were employed for the qualita- tive and quantitative analysis respectively. Totally, 160 constituents were ...
