ABSTRACT

At present, the modernization of Chinese medicine preparations (CMPs) is still a challenging task. The 3 typical Chinese medicine materials (CMMs) used for preparing CMPs are the powders, extracts, and components of Chinese medicine and their properties of CMMs are important for designing CMPs. Basing on our long term research, we have established a property system for CMMs according to the state of CMMs under an exactly condition and according to the interaction characteristics between substances. The property system could be divided into 5 categories: material composition, spatial structure, body property, surface property, physicochemical properties, and they could also be divided into 18 subcategories. Furthermore, we also established the corresponding index and characterization system, where the 61 indexes and characterization techniques were systematically summarized. At last, we hope that the article will promote the modernization of CMPs.

ABSTRACT

The study is to develop a method to determine 3 batches leaves of Nauclea officinalis and stems of N. officinalis by HPLC. The differences between strictosamide contents and fingerprints was compared, then chromatographic peak of fingerprints was validated with the assistance of LC-MS. The strictosamide contents in stems of N. officinalis were higher than leaves of N. officinalis. The main chemical composition in leaves of N. officinalis and stems of N. officinalis were alkaloid which revealed by LC-MS. There are 7 chemical compositions were same between them, but the chemical composition in leaves of N. officinalis is more than stems of N. officinalis. This provides a scientific basis for the development of the potential medicinal value of leaves of N. officinalis and the sustainable utilization of N. officinalis.
