摘要:

为探究不同加工方式对浙贝母指标成分含量的影响及其与体外抗病毒活性的相关性,本研究采用高效液相色谱法分别测定浙贝母品种浙贝1号、浙贝2号、浙贝3号经不同加工方式处理后样品中贝母素甲和贝母素乙的含量,通过检测提取液对神经酰胺酶的抑制率,评估各样品的体外抗病毒活性,并结合主成分分析(PCA)、聚类分析等多元分析方法,对浙贝母的品质变化进行系统解析。结果显示,贝母素甲含量范围为0.019 8%~0.077 8%,贝母素乙为0.013 2%~0.040 4%。在不同品种中,片贝加工方式均使其指标成分含量达到最高。不同加工方式下样品的抗病毒效价范围在1.446 5~10.596 2 U·mg-1,总体趋势为冻干 > 片贝 > 灰贝。PCA与聚类分析显示,同一加工方式的样品自然聚集为一类。相关分析的结果显示,贝母素甲和贝母素乙含量间存在强相关性,但两者与抗病毒活性的相关性均不显著。随机森林模型能准确识别不同加工方式的样品。本研究通过对浙贝母指标成分及其抗病毒活性的测定,明确了不同加工方式引起的浙贝母化学特征与体外生物活性差异,为浙贝母的质量控制提供了理论依据。

Abstract:

To investigate the effects of different processing methods on the content of marker components in Fritillaria thunbergii and their correlation with antiviral activity in vitro,this study determined the contents of peimine and peiminine in samples of F. thunbergii cultivars Zhebei 1,Zhebei 2,and Zhebei 3 processed by different methods using high-performance liquid chromatography. Meanwhile,the antiviral activity in vitro of each sample was evaluated by measuring the inhibitory rate of the extracts on neuraminidase. Multivariate analytical methods,including principal component analysis(PCA)and cluster analysis,were employed to systematically interpret the quality variations of F. thunbergii. The results indicated that the peimine content ranged from 0.019 8% to 0.077 8%,while the peiminine content ranged from 0.013 2% to 0.040 4%. Among the different cultivars,the slice-dried processing method consistently yielded the highest levels of marker components. The antiviral potency of the samples varied between 1.446 5 and 10.596 2 U·mg-1,with an overall trend of freeze-dried F. thunbergii > slice-dried F. thunbergii > shell powder-processed F. thunbergii. PCA and cluster analysis revealed that samples processed by the same method naturally clustered into one group. Correlation analysis demonstrated a strong correlation between peimine and peiminine contents,but no significant correlation was found between the contents of these components and the antiviral activity. The random forest model accurately identified samples processed by different methods. By determining the marker components and antiviral activity of F. thunbergii,this study clarifies the differences in chemical characteristics and in vitro biological activity induced by different processing methods,providing a theoretical foundation for its quality control.
