This paper described an improved total quality assessment method for Chrysanthemum indicum Flower by simultaneous quantitation using a single standard to determine multi-components method combined with high performance liquid chromatography fingerprint analysis. Six main components of Chrysanthemum indicum Flower including two flavonoids and four phenolic acids were simultaneously quantified using linarin as the internal reference standard. The method was fully validated with respect to linearity, precision, accuracy, robustness and stability.The validated method was successfully applied to the analysis of thirty three batches of Chrysanthemum indicum Flower samples. Under the same chromatographic conditions, fingerprint analysis in combination with Similarity analysis and principal component analysis was performed to identify the samples from different regions. In general, an effective assessment using a single standard to determinate multi-components method combined with fingerprint analysis make the reliable qualitation and quantitation analysis of Chrysanthemum indicum Flower available.展开更多
A new bicyclic spiroketone was isolated from the bud of Chrysanthemum indicum L. The chemical structure was elucidated as (1R, 9S, 10S)-10-hydroxyl-8 (2', 4'-diynehexylidene)- 9-isovaleryloxy-2, 7-dioxaspiro [5,...A new bicyclic spiroketone was isolated from the bud of Chrysanthemum indicum L.

Des Moul.flower from eleven locations was analyzed by HPLC.The results show that linatin and luteolin contents in samples are higher with a range of 0.0-13.3 and 0.5-2.1 mg·g-1,respectively,and suitable for quantitative determination,while apigenin and quercetin contents are trace and suitable for qualitative determination.The content of flavonoids is obviously affected by locations.No linatin is detected in samples from Jiangxi and Nanyang of He’nan.The content of linatin and luteolin is higher in samples from Chuzhou of Anhui,Nanjing of Jiangsu and Inner Mongolia.D.indicum flower from Chuzhou of Anhui is superior for having all four flavonoids and higher content of linatin and luteolin.展开更多
