ABSTRACT
Objective: To optimize the processing technology of cooked Rhei Radix et Rhizoma (RRR), and to quantify the judgment standard of concocting end point. Methods: The optimum technology of combination of single factor and orthogonal design was used to determine the optimum technology of aloe-emodin, rhein, emodin, chrysophanol, emodin, and total anthraquinone. The color value of processed products was quantified using the color difference measurement. Results: The steaming time had significant effect on the content of total anthraquinone in RRR, but the steaming time and steaming temperature had no statistical significance. The values of L (4 mm), a (4 mm, 8 mm), and b (4 mm) were significantly positive (negative) with chrysophanol, emodin, emodin, aloe-emodin, and total anthraquinone. The results showed that there was a significant positive correlation between rhein and b (8 mm) values, and the linear regression equation was Y = 0.288 + 0.007 X. Conclusion: The best processing technology of cooked RRR is: RRR and 30% yellow wine were moisten for 3.5 h, set at 100 ℃ steam for 1.5 h. Concocted the end point of cooked RRR processing scientifically determine that can be determined by the L, a, and b color values. And also for the in-depth study of traditional Chinese medicine concocted the end to determine the method laid the foundation.
ABSTRACT
At the urgent practical issue of resource protection and artificial cultivation area selection of Dioscorea nipponica, the dominant environmental factors affecting the distribution of D. nipponicain Jilin province were selected by field investigation and using the maximum information entropy model and geographic information technology. MaxEnt model study found that the standard deviation of seasonal variation of temperature, precipitation in October and other six environmental factors on the growth of D. nipponica are the greatest impacting factors. The range of suitability for the growth of D. nipponica was 4.612 08×10-6-0.544 31, and the regionalization study was divided into four parts: high fitness area, middle fitness area, low fitness area and unfavorable area. The high fitness area is concentrated in the central and southern areas of Jilin Province, using ArcGIS statistical environment factors in the appropriate area of the numerical situation. The results showed that the regionalization study of D. nipponica was basically the same as the actual situation. It is clear that the natural environment suitable for the growth of D. nipponica is also the basis for the protection of the resources and the selection of cultivated area.
ABSTRACT
This paper is aims to clarify the spatial distribution of high quality medicinal materials Schisandrae Chinensis Fructus. Based on investigation and field investigation, the samples and distribution information of Schisandrae Chinensis Fructus were collected. Based on the data of four kinds of lignin chemical constituents, ecological environment factors and spatial distribution data of Schisandrae Chinensis Fructus, using GIS technology, maximum information entropy model and SPSS statistical analysis method for regionalizing the quality of Schisandrae Chinensis Fructus. The results showed that Schisandrae Chinensis Fructus was mainly distributed in the northeast of Liaoning, east of Jilin, east of Heilongjiang. The content of schisandrin was higher in the samples from northeastern part of Jilin province and the northeastern part of Liaoning province, The content of deoxyschizandrin was higher in the samples from middle of Jilin province and northeastern Hebei province, where the content of schisandrin B was higher in the samples from Jilin area, The higher schisantherin A sample were from southeast of Jilin and northeast of Liaoning. Considering the content of four components in Schisandrae Chinensis Fructus, the quality of Schisandrae Chinensis Fructus was concentrated in the southeast of Jilin and the northeastern part of Liaoning.
