Production regionalization study of Isatidis Radix / 中国中药杂志

In this research, we collected information of eighty nine sampling points of Isatidis Radix nationwide through data query and field survey, and the medicinal component contents of samples were determined by HPLC. By using Maxent Model and ArcGIS, along with ecological factor data, the national habitat suitability distribution of Isatidis Radix was predicted. R-language was adopted to establish a model of the relationship between the medicinal component contents and ecological factors. The medicinal quality was divided by ArcGIS grid computing. The results indicated that the three main ecological factors affecting the distribution of Isatidis Radix were precipitation in the driest season, mean annual temperature and mean temperature in the wet season. The suitable cultivation region of Isatidis Radix is mainly distributed in the north of China, but the medicinal quality is quite different, Isatidis Radix in Xinjiang province has higher medicinal quality. This study provides a reference for rational selection of planting areas of Isatidis Radix.

Verification of processing theory of "reducing ketone and dryness, and increasing ester and effect" for bran-fried atractylodes / 中国中药杂志

We previously proposed the processing theory of "reducing ketone and dryness, and increasing ester and effect" for bran-fried atractylodes, and made a preliminary study. To further verify the science and rationality of the theory, we determined the changes in the content of atractylenolide I, II, III and atractylon in atractylodes after and before being fried with bran, in order to compare the effect of raw and bran-fried atractylodes on the water intake and urination in rats in this study. The effect of raw and bran-fried atractylodes on the content of four gastrointestinal hormones and two neurotransmitters in serum was observed in an attempt to verify the science and rationality the processing theory of "reducing ketone and dryness, and increasing ester and effect" for bran-fried atractylodes.
