赤芍挥发性成分的GC-MS与直观框导式演进特征投影法分析
Analysis of Volatile Chemical Components in Radix Paeoniae Rubra by GC-MS and Heuristic Evolving Latent Projections Method
【摘要】 目的定性、定量分析赤芍中挥发性成分、方法利用气相色谱-质谱(GC-MS)进行检测,再通过直观推导式演进特征投影(HELP)法对产生的二维色谱-质谱数据进行解析,得到各组分的纯色谱曲线和质谱,根据其保留时间和质谱,在质谱库中进行相似检索,实现对组分的定性,再用总体积积分法进行定量。结果共分辨出57个色谱峰,通过质谱库对分辨的纯组分进行检索,鉴定了其中38个组分,占赤芍挥发成分总合量的95.21%。结论赤芍主要挥发成分为(Z,Z)-9,12-十八碳二烯酸,正十六碳酸和水杨醛。
【Abstract】 OBJECTIVE To analyze the volatile chemical components of Radix Paeoniae Rubra(RPR).METHODS Gas chromatography-mass spectrometry(GC-MS),heuristic evolving latent projections(HELP)method,and overall volume,integration methods were used.RESULTS Thirty- eight volatile chemical components in RPR were determined,accounting for 95.21% of volatile chemical components of RPR.CONCLUSION The mail volatile chemical components of RPR are(Z,Z)-9,12-octadecadienoic acid,n-hexadecanoic acid and 2-hydroxy-benzaldehyde.
