目的:探索丹参中丹参酮ⅡA的含量变化规律,寻找不同研究结果存在差异的原因。方法:结合本课题组的研究结果,并收集了1997年以来不同产地丹参酮ⅡA的含量测定数据,进行探索性数据分析和描述性统计分析。结果和结论:丹参野生药材中丹参酮ⅡA含量普遍高于栽培品,近50%栽培品丹参酮ⅡA低于0.2%;数据的统计模式存在较大的差异,引起数据差异较大,其中以四川产地的数据分歧最大;野生丹参的变异系数低于栽培品,不同产地栽培丹参的变异系数不同,反映出质量的均一性和稳定性不同;市购样品的变异系数大于自采样品;加热回流提取法得到丹参酮ⅡA结果偏低。
Objective: To explore the changes of tanshinone IIA in Salvia miltiorrhiza Bunge, and to find out the reasons for the differences in the results of different studies. Methods: Combining with the research results of this group, the data of tanshinone IIA in different producing areas since 1997 were collected, exploratory data analysis and descriptive statistical analysis. RESULTS AND CONCLUSION: The tanshinone IIA content in wild herbs of Salvia miltiorrhiza is generally higher than that in the cultivated products, and nearly 50% of the cultivated tanshinone IIA is lower than 0.2%; the statistical patterns of the data are quite different, causing a large difference in data, among which the origin of Sichuan The data were the most divergent; the variation coefficient of wild Salvia miltiorrhiza was lower than that of cultivated crops, and the variation coefficient of Salvia miltiorrhiza was different in different habitats, reflecting the uniformity of quality and stability; the coefficient of variation of commercially available samples was larger than that of self-sampled samples; Tanshinone IIA results are low.
