Analysis of volatile constituents and chemical relationship of cultivated and wild Angelica dahurica / 南方医科大学学报

OBJECTIVE@#To determine the volatile constituents and their contents in the roots of 5 cultivated Angelica dahurica and one wild A. dahurica and analyze the chemical relationship among the plants of A. dahurica.@*METHODS@#The essential oil was extracted from the roots of 5 cultivated plants of Angelica dahurica and one wild A. dahurica by water steam distillation. Gas chromatography-mass spectrometry (GC-MS) was used to separate and identify all the volatile oil components in the extracts, and their relative contents were calculated with area normalization method. We also conducted clustering analysis and principal component analysis of the volatile oil components.@*RESULTS@#We identified a total of 81 compounds from the roots of the 6 plants of Angelica dahurica, including 27 in Chuanbaizhi (Angelica dahurica cv. 'Hangbaizhi'), 34 in Hangbaizhi (Angelica dahurica cv. 'Hangbaizhi'), 24 in Qibaizhi (Angelica dahurica cv. 'Qibaizhi'), 32 in Yubaizhi (Angelica dahurica cv.'Qibaizhi'), 28 in Bobahizhi (Angelica dahurica cv.'Qibaizhi'), and 34 in Xinganbaizhi (Angelica dahuirca). These compounds included, in the order of their relative contents (from high to low), alkanes, olefins, esters, organic acids and alcohols. Among the common components found in the roots of all the plants of A. dahurica, nonylcyclopropane, cyclododecane and hexadecanoic acid were identified as the volatile oil components that showed the highest relative contents. Clustering analysis of the volatile oil components showed that wild Angelica dahurica (Xing'anbaizhi) and the 5 cultivated Angelica dahurica (Chuanbaizhi, Hangbaizhi, Qibaizhi, Yubaizhi, Bobaizhi) could be divided into two groups, and the cultivated Angelica dahurica could be divided into two subgroups: Chuanbaizhi, Yubaizhi and Hangbahizhi were clustered in one subgroup, and Qibaizhi and Bobaizhi in another. The results of principal component analysis was consistent with those of clustering analysis.@*CONCLUSION@#The main volatile oil components and their contents vary among the 6 plants of A. dahurica. Nonylcyclopropane, cyclododecane and hexadecanoic acid are the most abundant volatile oil components in all the plants of A. dahurica, which can be divided into two clusters.

Chemical relationship study of aconitum soongaricum stapf based on HPLC fingerprint / 中国药学杂志

OBJECTIVE: To compare the HPLC fingerprints Aconitum soongaricum Stapf. with Aconitum carmichaelii Debx., Aconitum kusnezoffii Reichb., and another common radix aconite plant in Xinjiang, Aconitum leucostomum Worosch., and analyze the degree similarity between different fingerprints. METHODS: The HPLC fingerprint Aconitum soongaricum Stapf was established, and similarity analysis, cluster analysis and principal component analysis were carried out for the common patterns, Aconitum soongaricum Stapf and Aconitum carmichaelii Debx., Aconitum kusnezoffii Reichb., and Aconitum leucostomum Worosch. via the ChemPattem chemical fingerprint analysis system software solutions. RESULTS: The analysis showed that the similarities the mutual model reference fingerprints were higher between Aconitum soongaricum Stapf and Aconitum kusnezoffii Reichb. and between Aconitum leucostomum Worosch. and Aconitum carmichaelii Debx. CONCLUSION: It is preliminarily determined that Aconitum soongaricum Stapf in Xinjiang had higher similarity with the legal standard Aconitum kusnezoffii Reichb., which deserves further research and development.
