Eigenvalue and Variance Contribution Rate for Ligusticum Chuanxiong Chemical Analysis

A comparative chemical analysis of two varieties of the medicinal herb Ligusticum chuanxiong from Gansu Province. The dataset includes measurements of odor, color, volatile components, and chemical constituents like ligustilide and senkyunolides, with correlations to altitude. The data was authored by Jialing Zhang and last updated on April 30, 2026.

Use Cases

• Classify herb varieties based on chemical constituent concentrations like ligustilide and senkyunolides.
• Model correlations between environmental factors (e.g., altitude) and phenotypic traits like odor and color.
• Compare volatile compound profiles between plant varieties using HS-SPME-GC-MS data.
• Establish chromatographic fingerprint profiles for quality control of medicinal herbs.

Strengths

• Quantifies 82 volatile compounds in one variety and 62 in another, with 34 shared compounds.
• Includes specific chemical constituent measurements (ligustilide, senkyunolide I, H, 3-butylphthalide) with statistical significance (p < 0.01).
• Integrates multiple analytical methods: electronic nose, colorimeter, HS-SPME-GC-MS, and HPLC.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
