摘　　要：目的:基于“辨状论质”理论研究前胡外观性状与内在质量的相关性。方法:采用体视显微镜测量前胡木质部占比;采用分光测色仪采集前胡色度值;采用高效液相色谱法测定白花前胡甲素和白花前胡乙素含量;分析性状指标与药效成分含量的相关性。结果:白花前胡甲素质量分数与红绿值呈显著负相关,说明红绿值越低,白花前胡甲素含量越高;白花前胡甲素质量分数与白花前胡乙素质量分数呈极显著正相关。结论:外观性状指标可作为前胡“辨状论质”的依据。研究结果为建立客观、科学的前胡质量评价方法提供了参考。Objective:To explore the correlation between appearance traits and the intrinsic quality of Peucedanum praeruptorum based on the theory of"quality evaluation through morphological identification".Methods:A stereomicroscope was used to measure the proportion of the xylem in P.praeruptorum;a colorimeter was used to collect chromaticity values;high-performance liquid chromatography(HPLC)was used to determine the content of praeruptorin A and praeruptorin B;and the correlation between appearance trait and the content of active ingredients was analyzed.Results:Praeruptorin A showed a significant negative correlation with the red green color value,indicating that the lower the red green color value,the higher the content of praeruptorin A;the content of praeruptorin A had a highly significant positive correlation with the content of praeruptorin B.Conclusion:Appearance trait indicators can be used as a basis for judging the quality of P.praeruptorum according to the theory of"quality evaluation through morphological identification".The research results provide a reference for establishing an objective and scientific quality evaluation method for P.praeruptorum.
