摘要
半枫荷是一种传统的中药材,其野生资源现已遭到严重破坏,濒临灭绝。为了更好地保护和利用半枫荷资源,人工栽培应运而生。本研究采用顶空-气相色谱-离子迁移谱法(HS-GC-IMS)结合主成分分析(PCA)对人工栽培和野生半枫荷中的挥发性有机化合物(VOCs)的变化进行分析。通过比较人工与野生品种半枫荷之间的差异来确定人工栽培半枫荷的药用价值。结果表明,半枫荷人工栽培和野生品种的VOCs组成相同,用于调节其药效的皮和茎中的挥发性有机化合物没有显着差异。该研究为人工栽培半枫荷的应用和野生品种的替代提供了科学理论。
Semiliquidambar cathayesis(SC)is often used as traditional Chinese medicine(TCM)in the market,and its wild resources are now severely damaged and on the verge of extinction.In order to preserve and apply SC resources preferably,artificially cultivated SC is generated.In the present study,the variations of volatile organic compounds(VOCs)in the artificially cultivated and wild SC were analyzed by headspace-gas chromatography-ion mobility spectrometry(HS-GC-IMS)combined with principal component analysis(PCA).The medicinal value of artificially cultivated SC was determined by comparing the differences between these SCs.The results showed that the artificially cultivated and wild SCs had the same composition for the VOCs,and the VOCs in the bark and stem used to adjust the efficacy of liquid medicine in SCs were not significantly different.Collectively,the findings provided a scientific theory for the application of artificially cultivated SC and the replacement of wild SC.
