摘要

本文提供了一种结合化学计量学的快速方法来可视化八个区域的PEL质量。采用分光光度法测定了矿物元素、维生素C（Vc）的含量和颜色参数。采用电子鼻（E-nose）和气相色谱-质谱（HS-SPME/GC-MS）顶空固相微萃取法测定挥发性物质。化学计量分析用于根据地理来源可视化样本分布。不同产地PEL的颜色参数、Vc和矿物含量差异显著（P<0.05）。从PEL中共鉴定出25种挥发性有机化合物，其中乙酸乙酯含量最高。HS-SPME/GC-MS和E-nose的组合可以正确地表征PEL样品。因此，这项探索性工作的结果突出了区分不同地区PEL的可能性。

Visualisation of Phyllanthus emblica L. quality using E-nose, HS-SPME/GC-MS, and spectrophotometric methods with chemometrics

This paper provides a rapid method coupled with chemometrics to visualise PEL quality of eight regions. The contents of mineral elements, Vitamin C (Vc), and colour parameters were measured using spectrophotometric methods. The volatile substances were determined by electronic nose (E-nose) and headspace solid phase micro-extraction with gas chromatography-mass spectrometry (HS-SPME/GC-MS). Chemometric analyses were employed to visualise the sample distribution according to the geographical origin. The colour parameters, Vc, and mineral contents of PEL from diverse origins were significantly different (P < 0.05). A total of 25 volatile organic compounds (VOCs) were identified from PELs, with the highest percentage of components being ethyl acetate. The combination of HS-SPME/GC-MS and E-nose can properly characterise PEL samples. Therefore, the results of this exploratory work highlight the possibility of discriminating PEL from different regions.
