A. Test Subjects
The test subject is radix astragali (astragalus root)[25]. Chinese name: 黄芪(huang-qi). Radix astragali is a widely used medicinal herb in traditional Chinese medicine (TCM). It is often used to treat diabetes and cardiovascular diseases.
The radix astragali samples are provided by a TCM pharmaceutical manufacturer. Radix astragalus is the main ingredient in one of their patent drugs.
The radix astragali samples come from four different provinces, i.e., Inner Mongolia (north China), Sichuan (southwest China), Shanxi (northwest China), and Gansu (northwest China). Herbs from different regions could have slightly different medicinal effectiveness, due to different cultivation conditions, climate, and environment.
B. Instrument
Instruments: Both Raman and UV are used to profile the radix astragali samples. The Raman spectrometer used in this study is ProttezRaman-D3, manufactured by Enwave Optronics, US. The ultraviolet-visible absorption spectrum is generated by a T6 ultraviolet-visible spectrometer, manufactured by Purkinje General Instrument, China.
Procedures: Each radix astragali sample is first processed in a high-speed grinder for 10 min at 25,000 rpm (round per minute). Every 3g of the ground powder is solved in 30 mL ethanol solution. Then, the mixture is stirred for 1 h at 100℃ with reflux. Let the mixture cool down and then filter it. Finally, test with Raman and UV spectrometers. The parameters for Raman are as follows. Laser wavelength: 785 nm. Laser power: 450mW. Exposure time: 5s.
C. Dataset
160 radix astragali samples are tested. Each category (province) has 40 samples.
The Raman and UV spectra are organized into two CSV (comma-separated value) files. Each row is one sample. The first column is the Y label (0-Inner Mongolia, 1-Sichuan, 2-Shanxi, 3-Gansu). The rest of the columns are Raman wavenumbers or UV wavelengths. Data file summary:

{'A': '测试对象
测试对象为黄芪根( astragalus root)[25]。中文命名为黄芪(huang-qi)。黄芪作为传统中医药(TCM)中广泛应用的药用草本,常用于治疗糖尿病和心血管疾病。
黄芪根样品由一家中医药制造商提供。黄芪是其专利药物的主要成分。
黄芪根样品来源于四个不同的省份,即中国内蒙古(北方)、四川(西南部)、山西(西北部)和甘肃(西北部)。由于不同的栽培条件、气候和环境,不同地区的草药可能具有略有差异的药用效果。', 'B': '仪器
使用的仪器包括拉曼光谱和紫外光谱,用于分析黄芪根样品。本研究中使用的拉曼光谱仪为Enwave Optronics制造的ProttezRaman-D3,美国制造。紫外-可见吸收光谱由Purkinje General Instrument制造的T6紫外-可见光谱仪生成,中国制造。
操作步骤:首先,每个黄芪根样品在高速研磨机中以25,000 rpm(每分钟转数)的速度研磨10分钟。然后将每3克磨碎粉末溶解在30毫升乙醇溶液中。接着,该混合物在100℃下回流搅拌1小时。待混合物冷却后进行过滤。最后,使用拉曼和紫外光谱仪进行测试。拉曼测试的参数如下。激光波长:785 nm。激光功率:450mW。曝光时间:5s。', 'C': '数据集
共测试了160个黄芪根样品。每个类别(省份)有40个样品。
拉曼和紫外光谱被组织成两个CSV(逗号分隔值)文件。每行代表一个样品。第一列是Y标签(0-内蒙古,1-四川,2-山西,3-甘肃)。其余列是拉曼波数或紫外波长。数据文件摘要:
7044.txt - 拉曼
X的含义:拉曼位移/波数
X的范围:100 ~ 4278 cm-1
分辨率:2cm-1
7143.txt - 紫外
X的含义:波长
X的范围:200 ~ 800 nm
分辨率:1 nm'}
