摘要
目的:为探讨野生息半夏与栽培息半夏之间的成分差异,对3个地区野生息半夏及栽培息半夏的总灰分、浸出物、总有机酸、总生物碱等成分进行比较和评价。方法:以水为溶剂采用冷浸法测定浸出物、采用灰分测定法测定总灰分,采用电位滴定法测定总有机酸含量,采用UV-VIS法测定生物碱含量,并结合SPSS T检验以及PCA-X分析对息半夏进行综合分析。结果:野生息半夏的总灰分、浸出物含量低于栽培息半夏,但总有机酸、总生物碱含量高于栽培息半夏。通过PCA-X分析显示不同地区栽培息半夏及野生息半夏的总灰分、浸出物成分特征无明显差异,但栽培及野生息半夏总有机酸、总生物碱样品特征差异明显,另外,通过比对野生及栽培息半夏的主成分特征,发现关店、陆湾栽培息半夏作为野生息半夏替代品具备一定的合理性。结论:与栽培品相比,野生息半夏总有机酸、总生物碱含量总体较高,栽培息半夏可代替野生息半夏临床应用。
Objective:To explore the composition difference between wild Xi Pinellia ternata and cultivated Xi Pinellia ternata.And the total ash,extract,total organic acids,total alkaloids,and other components of wild Xi Pinellia ternata and cultivated Xi Pinellia ternata in three regions were compared and evaluated.Methods:Use water as the solvent,cold leaching method was used to determine the extract,ash content method was used to determine the total ash content,the potentiometric method was used to determine the organic acid content,and the UV-VIS method was used to determine the alkaloid content.Combined with SPSS T-test and PCAX analysis,a comprehensive analysis of Pinellia ternata was carried out.Results:The total extract and total ash content of wild XI Pinellia ternata are lower than that of cultivated Xi Pinellia ternata,but the content of alkaloid and organic acid is higher than that of cultivated Pinellia ternata.PCA-X analysis showed that there was no significant difference in the total ash and extract composition characteristics of cultivated and wild Xi Pinellia ternata in different regions,but the alkaloid and organic acid characteristics of cultivated and wild Xi Pinellia ternata were significantly different.Also,by comparing the main component characteristics of wild and cultivated Xi Pinellia ternata,it is found that Guandian and Luwan cultivated Xi Pinellia ternata are reasonable as substitutes for wild Xi Pinellia ternata.Conclusion:Compared with cultivated products,the content of total alkaloids and organic acids in wild Xi Pinellia ternata is generally higher,however,cultivated Xi Pinellia ternata can replace wild Pinellia ternata for clinical application.
