On September 15, 2019, Li, Shang-Zhen; Guan, Xiang-Ming; Gao, Zhao; Lan, Hong-Ci; Yin, Qiang; Chu, Chu; Yang, De-Po; Liu, E-Hu; Zhou, Ping published an article.Quality Control of Methyl N-Methylanthranilate The title of the article was A simple method to discriminate Guangchenpi and Chenpi by high-performance thin-layer chromatography and high-performance liquid chromatography based on analysis of dimethyl anthranilate. And the article contained the following:
Citri Reticulatae Pericarpium (CRP), the dried pericarp of Citrus reticulata Blanco, can be divided into “Guangchenpi” (GCP, the dried pericarps derived from Citrus reticulata ‘Chachi’) and “Chenpi” (CP, the dried pericarps derived from other cultivars of Citrus reticulata Blanco). To discriminate between GCP and CP, a simple and reliable high-performance thin-layer chromatog. (HPTLC) method was firstly developed to analyze the volatile compound di-Me anthranilate, and a high-performance liquid chromatog. (HPLC) method was established to simultaneously quantify di-Me anthranilate and three predominant flavonoids (hesperidin, nobiletin and tangeretin) in CRP samples. Both the HPTLC anal. and HPLC-orthogonal partial least squares discrimination anal. (OPLS-DA) indicated that GCP can be effectively distinguished from CP based on anal. of di-Me anthranilate. Our results indicated that di-Me anthranilate can be used as a marker compound for discrimination of GCP and CP. This work provided a convenient approach which might be applied for quality evaluation of CRP. The experimental process involved the reaction of Methyl N-Methylanthranilate(cas: 85-91-6).Quality Control of Methyl N-Methylanthranilate
