Abstract:
The present work is to analyze the HPLC fingerprints of mulberry-sourced materials(Mori Ramulus, Mori Folium, Muri Cortex, Mori Fructus) using the fingerprint division total statistical moment method and information entropy, and to study the diffe-rences of the chemical components and the overall characteristics of the imprinting template in different parts of mulberry-sourced medicinal materials, so as to provide the basis for finding the effective substances in response to "homologous and different effect" of mulberry(Morus alba). The fingerprints of 24 batches of mulberry-related materials, such as Mori Ramulus, Mori Folium, Muri Cortex, Mori Fructus, were established, and the similarities and differences of the fingerprints were analyzed by calculating the division total statistical moment parameters and information entropy. The AUC_T, MCRT_T, VCRT_T and H values of 24 batches of mulberry-sourced materials were less than 0.05, with significant difference. Among them, all samples showed absorption peaks within 3-11, and 20-24 min, indicating that the four types had the identical or similar chemical composition in the same time period. After 34 min, none of the four types showed absorption peaks. Greater VCRT_T value of the fingerprints of the four kinds was observed at the retention time ranges of 3-4, 16-18, 25-27, and 31-32 min, indicating that the components of the four kinds were significantly different in these time periods; and VCRT_T value of the mulberry was significantly higher than that of the other three kinds of medicinal materials at the retention time windows of 3-4 and 15-17 min; the VCRT_T value of the mulberry white skin was significantly higher at the time windows of 8-10 and 28-30 min; the VCRT_T value of all four kinds was significantly higher within 21-23 min, indicating that the four herbs contain the same or similar components in the chromatogram during this period, but there may be significant differences between the content and the proportion. In addition, the information entropy of mulberry branches is the largest at 7-12, 23-27 min, and that of mulberry fruits is the largest at 2-8 min, which indicates that the components of mulberry branches and mulberry fruits respond greatly in the corresponding period of time, which is also the main peak period of their chemical components. For the chemical components and corresponding efficacy here. The results showed that there are significant differences in the components and contents of mulberry-sourced medicinal materials. The division total statistical moment and information entropy of the total amount of segments can be used to analyze the differences in the components of "homology and different effects", which could provide a more comprehensive analysis method for the determination of quality markers.
