Multivariate Econometric Analysis Based on Trace Elements and Thermogravimetric Analysis Indicators of Gynostemma Pentaphyllum,Lysimachia Japonica,and Buckwheat
Three types of heat clearing and detoxifying Chinese herbal medicines,including Gynostemma pentaphyllum,Lysimachia japonica,and Buckwheat,produced in Jinxiu,Guangxi,were selected as the research objects.The combustion heat,combustion stability,fat,crude fiber,ash content,and trace elements of these three Chinese herbal medicines were measured,and the quality of Chinese herbal medicines was studied from multiple indicators.The results showed that the combustion heat of three traditional Chinese herbs,including Gynostemma pentaphyllum,Lysi-machia japonica,and Buckwheat,ranged from 15493.55 to 24188.85 J/g;The ranking of combustion stability is:Gynostemma pentaphyllum>Buckwheat>Lysimachia japonica;The fat content(%)ranges from0.12%to 0.28%,and the order of magnitude is:Lysimachia japonica>Buckwheat>Gynostemma pentaphyllum;The ash content(%)ranges from 7.85%to 8.66%,in the following order:Gynostemma pentaphyllum>Lysimachia japonica>Buckwheat;The crude fiber content(%)ranges from 21.85%to 31.90%,and the order of magnitude is:Lysimachia japonica>Gynostemma pentaphyllum>Buckwheat.The order of multiple indicators including combustion heat,combustion stability,fat content,ash content,crude fiber content,and trace element content is as follows:Gynostemma pentaphyllum>Lysimachia japonica>Buckwheat.This study establishes a multi index analysis and evaluation system for three Chinese herbal medicines:Gynostemma pentaphyllum,Lysimachia japoni-ca,and Buckwheat.This provides a theoretical basis and scientific guidance for the quality evaluation and comprehensive utilization of Chinese herbal medicines.
