| Abstract
|
| [Objective] Based on the content determination of the chemical components of Pinellia ternate from 17 production areas and sample areas in 5 producing areas,the accumulation rules of chemical components and the overall quality characteristics of Pinellia ternate from different habitats were clarified.[Methods] The total organic acid content was determined by potentiometric titration,the polysaccharides and alkaloids content was determined by UV-VIS,and the water-soluble hot-dip method was used to determine the total extractable content. Use principal component analysis to analyze data.[Results] Based on the pharmacopoeia index component succinic acid content (2.5 mg/g),each producing area is 1.06~4.31 mg/g,of which the content of 5 producing areas is lower than the pharmacopoeia standard. Based on the alkaloid content,0.50~0.70 mg/g,the content levels are similar;the content of extracts varies widely among samples from different producing areas,among which the Jingzhou content in Hubei is as high as 497.76 mg/g;the content of polysaccharides in different producing areas varies greatly,the average content in Gansu producing areas is generally higher,and the content in Xihe County is 214.19 mg/g;the contents of extracts,polysaccharides,and organic acids in wild Pinellia ternata are higher than those in cultivated Pinellia ternata;the contents of extracts,polysaccharides,and organic acids in Pinellia ternata after sulfur fumigation all decrease,and the content of alkaloids basically unchanged.[Conclusion] Jingzhou in Hubei and Xihe in Gansu are high-quality production areas of Pinellia ternata. The chemical compounds of the two places have higher overall levels of chemical components. Compared with cultivated products,the overall level of the chemical components of wild Pinellia ternata is higher,and the sulfur fumigation process resulted in the decrease of the content of each component in Pinellia ternata. |
