摘要：从蛇床子市场分级的角度,揭示外观性状评定蛇床子质量等级的科学内涵,为蛇床子运用外观性状进行等级标准的制定提供实验依据。以30批不同等级的蛇床子为研究对象,运用典型相关性分析和主成分分析(PCA)等统计方法,对15项外观性状与内在含量指标测量值进行探索。相关性分析结果显示,除长宽比外,5项外观性状类指标(长、宽、千粒重、碎粒质量占比、色度)与9项内在含量类指标(水分、总灰分、酸不溶性灰分、蛇床子素、欧前胡素、佛手柑内酯、异虎耳草素、花椒毒素、花椒毒酚)间,均呈现出不同程度的显著相关性。且外观性状类指标构成的第一典型变量U1与内在含量类指标构成的第一典型变量V1之间存在极显著的正相关性(CR1=0.963,P<0.01)。PCA结果显示,外观性状指标对30批蛇床子的等级划分结果与样品的实际信息相符合。在相同的分析条件下,通过9组内在含量指标重新对30批蛇床子进行等级划分,分析结果保持一致。性状分级标准研究发现,蛇床子6项外观性状的统计呈现出与统货和选货的相关性,且2个等级间的外观性状与内在含量之间存在良好的相关性,外观性状的优劣可以有效地预测内在含量的高低,通过主要的性状特征对蛇床子进行质量等级划分具有一定的科学依据,外观分级能够代替质量分级,实现蛇床子药材的辨状论质。
From the perspective of market classification of Cnidii Fructus, this paper revealed the scientific connotation of evaluating the quality grade of Cnidii Fructus by its appearance traits. Thirty batches of Cnidii Fructus in different grades were selected as the research objects. The canonical correlation analysis and principal component analysis(PCA) were used to explore the measurement values of 15 appearance traits and intrinsic content indexes. The results of correlation analysis showed that except the aspect ratio, the 5 appearance trait indexes(length, width, 1 000-grain weight, broken grain weight proportion, and chroma) and 9 internal content indexes(the content of moisture, total ash, acid insoluble ash, osthole, imperatorin, 5-methoxy psoralen, isopimpinellin, xanthotoxin, and xanthotol) showed significant correlation to varying degrees. In addition, there was a significant positive correlation between the first typical variable U1composed of appearance traits and the first typical variable V1composed of internal content indexes(CR1=0.963, P<0.01). The results of PCA showed that the classification results of appearance traits for 30 batches of Cnidii Fructus were consistent with the actual information of the samples. Under the same analysis conditions, 30 batches of Cnidii Fructus were reclassified by 9 groups of internal content indexes, and the analysis results were consistent. From the classification standard of the appearance traits of the system study, the statistical results of 6 appearance traits of Cnidii Fructus showed a correlation with grades. There was a good correlation between the appearance and the internal content of Cnidii Fructus, and the appearance quality effectively predicted the level of the internal content. There is a certain scientific basis for the quality classification of Cnidii Fructus by main appearance traits. Appearance classification can replace quality grading to realize the "quality evaluation through morphological identification" of Cnidii Fructus.
