Outline
This research is dedicated to constructing a quality assessment model for Shanzha (Crataegi Fructus) by employing the entropy-weight method in conjunction with the grey-relational-analysis-TOPSIS approach. The objectives are to assess the quality disparities among Shanzha (Crataegi Fructus) and its processed derivatives (stir-fried and scorched products) sourced from diverse regions and to furnish a scientific foundation for the quality control of hawthorn.
Water content, extract content, organic acid content, polysaccharide yield, total polysaccharide content and active components (chlorogenic acid, hyperoside, and isoquercetin) were selected as detection indices. The entropy-weight method was utilized to determine the weight of each index, and the grey-relational-analysis-TOPSIS method was applied to analyze the quality of Shanzha (Crataegi Fructus) and its processed products from six regions, namely Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei and Shandong.
The study revealed that the processing procedures significantly decreased the water content, organic acid content, polysaccharide content and active component contents in Shanzha (Crataegi Fructus). The water content of raw materials ranged from 8% to 12% and dropped to 5%-11% after processing. The organic acid content decreased from 6%-10.5% in raw products to 4%-7.7% in scorched products. The polysaccharide yield decreased from 7%-8.3% in raw materials to 4.6%-5.2% in scorched products. The total active component contents decreased from 0.082 7%-0.139 4% in raw products to 0.024 8%-0.069 5% in scorched products. Shanzha (Crataegi Fructus) from Hebei and Shandong demonstrated superior performance in multiple indices. The extract content (39%-41% in raw products), organic acid content (9%-10.5% in raw products) and total active component content (0.13%-0.14% in raw products) were markedly higher than those in other regions.
The quality evaluation model grounded in the entropy-weight method and the grey-relational-analysis-TOPSIS method offers a standardized and quantitative instrument for evaluating the quality of Shanzha (Crataegi Fructus) and its processed products. It contributes to standardizing the quality control of Shanzha (Crataegi Fructus) within the Chinese medicine industry and promotes the upgrading of Shanzha (Crataegi Fructus) planting industries in various regions and the enhancement of the Chinese medicine industry chain.
