And the article contained the following:
To get a better understanding of the bioactive constituents in Aurantii Fructus Immaturus (AFI) and Aurantii Fructus (AF), in the present study, a comprehensive strategy integrating multiple chromatog. anal. and chemometrics methods was firstly proposed. Based on segmental monitoring, a high-performance liquid chromatog. (HPLC)-variable wavelength detection method was established for simultaneous quantification of ten major flavonoids, and the quant. data were further analyzed by hierarchical cluster anal. (HCA) and principal component anal. (PCA). A strong cation exchange-high performance liquid chromatog. (SCX-HPLC) method combined with t-test and one-way anal. of variance (ANOVA) was developed to determine synephrine, the major alkaloid in AFI and AF. The essential oils were analyzed by gas chromatog.-mass spectrometry (GC-MS) and further processed by partial least squares discrimination anal. (PLS-DA). The results indicated that the contents of ten flavonoids and synephrine in AFI were significantly higher than those in AF, and significant difference existed in samples from different geog. origins. Also, 9 differential volatile constituents detected could be used as chem. markers for discrimination of AFI and AF. Collectively, the proposed comprehensive anal. might be a well-acceptable strategy to evaluate the quality of traditional citrus herbs. The experimental process involved the reaction of Methyl N-Methylanthranilate(cas: 85-91-6).Quality Control of Methyl N-Methylanthranilate
