Entropy analysis and grey cluster analysis of multiple indexes of 5 kinds of genuine medicinal materials

Abstract

Abstract5 kinds of genuine medicinal materials, including Diding (Latin name: Corydalis bungeana Turcz), Purslane (Latin name: Portulaca oleracea L.), straw sandal board (Latin name: Hoya carnosa (L.f.) R. Br), June snow (Latin name: Serissa japonica (Thunb.) Thunb.), pine vine rattan (Latin name: Lycopodiastrum casuarinoides (Spring) Holub. [Lycopodium casuarinoides Spring]), were selected as the research objects. The combustion heat, thermo gravimetric parameters, and fat content, calcium content, trace element content, ash content of 5 kinds of genuine medicinal materials were measured. The combustion heat, differential thermal gravimetric analysis, fat content, calcium content, trace elements content, and ash content of 5 kinds of genuine medicinal materials were used to build a systematic multi-index evaluation system by gray pattern recognition and grey correlation coefficient cluster analysis, which can make up for the gaps in this area and provide scientific basis and research significance for the study of genuine medicinal materials quality. The results showed that the order of combustion heat of 5 kinds of genuine medicinal materials, including Diding, Purslane, straw sandal board, June snow, pine vine rattan, was Diding > June snow > straw sandal board > Purslane > pine vine rattan, the order of fat content (%) of 5 kinds of genuine medicinal materials was straw sandal board > Diding > pine vine rattan > June snow > Purslane, the order of calcium content (%) was pine vine rattan > June snow > Purslane > straw sandal board > Diding, the order of ash content was June snow > Purslane > straw sandal board > pine vine rattan > Diding. From the analysis of thermogravimetric analysis results and thermogravimetric combustion stability, the order of combustion stability of 5 kinds of genuine medicinal materials was June snow > pine Vine rattan > straw sandal board > Diding > Portulaca oleracea. The order of the content of 12 trace elements in 5 kinds of genuine medicinal materials, in terms of trace element content, June snow contains the highest trace elements in all samples. According to combustion heat, combustibility (combustion stability of genuine medicinal materials), fat, calcium, ash, trace element content, the comprehensive evaluation results of multi-index analysis constructed by gray correlation degree, gray correlation coefficient factor analysis, and gray hierarchical cluster analysis showed that the comprehensive evaluation multi-index order of 5 genuine medicinal materials, including Diding, Purslane, straw sandal board, June snow and pine vine rattan, was June snow > straw sandal board > Diding > Purslane > pine vine rattan. Therefore, the comprehensive evaluation results of the quality of genuine medicinal materials selected in this study were June snow the best, followed by straw sandal board. This research has important theoretical and practical significance for the multi-index measurement and comprehensive evaluation of genuine medicinal materials, and can provide scientific basis and research significance for the research of multi-index quality control of genuine medicinal material.

Effect of Soaking of Seeds in Water and Storage Period in a Regular Refrigerator to Produce Sprouts of some Vegetables for Marketing Purposes

“…Purslane is very rich in minerals and nutrients [43], as well as mustard and radish, but as purslane absorbs salts [44], this may explain the early calcium rise despite the plant's small size. These results are consistent with those of [45] in that the purslane plant is a strong absorbent of salts which agrees with [46] in that purslane is a plant rich in calcium.…”

Research on the quality markers of antioxidant activity of Kai-Xin-San based on the spectrum–effect relationship

“…In this study, 12 combinations were selected by the random number table method from 81 permutations of Polygalae Radix, Ginseng Radix et Rhizoma, Poria cocos, and Acori Tatarinowii Rhizoma with different producing origins ( Zhou et al, 2022 ). Then, Polygalae Radix, Ginseng Radix et Rhizoma, Poria cocos, and Acori Tatarinowii Rhizoma were separately crushed, sieved, and mixed with a weight ratio of 1: 1: 2: 1 to obtain KXS ( Zhang and Zeng, 2020 ).…”

Entropy analysis and grey correlation coefficient cluster analysis of multiple indexes of 5 kinds of condiments

“…The combustion heat, thermo gravimetric analysis, determination of calcium content, fat determination and ash determination data were determined (Zhou et al, 2022c); Crude fiber contents (Zhou et al, 2022d) and trace element contents (Ikem & Egilla, 2008;Misic et al, 2022) were determined. According to the combustion heat, thermo gravimetric parameters, fat contents, crude fiber contents, calcium content contents, trace element contents and ash contents, entropy analysis and grey correlation coefficient cluster analysis of multiple indexes for 5 kinds of condiments were performed in Guangxi, China.…”
