Abstract：
In this study, thirty-four samples of Laggera crispata (Vahl) Hepper & J. R. I. Wood from five main production areas in Yunnan Province, were collected for experimentation. UPLC- PDA was used to generate fingerprints and the common peaks were analysed through R and SIMCA-P. L. crispata from different origins can be distinguished by OPLS-DA and PCA. The VIP values were compared, and 8 characteristic components with great differences were obtained. It was confirmed that the two characteristic components were chrysosplenetin and artemisetin, and the quantitative analysis was performed with these two compounds from L. crispata samples with different origins. Based on the variance analysis results, the most significant difference in the content of chrysosplendin and artemisin was in Lancang and Honghe and Lancang and Simao, respectively. The chrysosplenetin can be used as an important indicator for quality control and to trace the origin of L. crispata.
摘要：
在这项研究中,来自云南省五个主产区的34个Laggeracrispata（Vahl）Hepper和J.R.I.木材样品，被收集用于实验。UPLC-PDA用于产生指纹，并通过R和SIMCA-P分析常见峰。可以通过OPLS-DA和PCA来区分不同来源的L.crispata。比较了VIP值，得到了8个差异较大的特征成分。证实了这两种特征成分是黄脾素和青蒿素，并对这两种来自不同来源的薯片样品的化合物进行了定量分析。根据方差分析结果，澜沧江和红河、澜沧江和思茅的含量差异最大，分别。菊花素可以作为一种重要的质量控制指标，也可以作为一种重要的质量控制指标，并可以用来追踪脆皮的起源。
