No subscription. No API calls. Instant download.** ## Why This Dataset Exists Large language models hallucinate botanical taxonomy. A biotech team's RAG pipeline confidently outputting "Quercetin found in 450 species at 2.3 mg/g" sounds plausible โ€” but the real number of species in our data is 215, and dosage varies by three orders of magnitude depending on the plant part. The raw USDA Dr. Duke's database is spread across 16 relational tables. Joining them correctly requires understanding non-obvious foreign keys, handling >40% null values in application fields, and normalising species names against accepted binomial nomenclature. Most teams give up after a week. ## Quickstart ### Python โ€” Load 400-row sample ```python import pandas as pd url = "https://raw.githubusercontent.com/wirthal1990-tech/USDA-Phytochemical-Database-JSON/main/ethno_sample_400.json" df = pd.read_json(url) print(f"{df.shape[0]} records, {df['chemical'].nunique()} unique compounds") df.head() ``` ### PyArrow โ€” Parquet (full dataset, after purchase) ```python import pyarrow.parquet as pq table = pq.read_table("ethno_dataset_2026_v2.parquet") print(f"Schema: {table.schema}") print(f"Rows: {table.num_rows} Memory: {table.nbytes / 1e6:.1f} MB") ``` ### DuckDB (analytical queries, no install required) ```python import duckdb result = duckdb.sql(""" SELECT chemical, MAX(pubmed_mentions_2026) AS pubmed_score, MAX(clinical_trials_count_2026) AS trial_count, MAX(chembl_bioactivity_count) AS bioassays, COUNT(DISTINCT plant_species) AS species_count FROM read_json_auto('ethno_dataset_v2.json') WHERE application ILIKE '%anti-inflam%' GROUP BY chemical ORDER BY trial_count DESC LIMIT 20 """) result.show() ``` ### HuggingFace Datasets ```python from datasets import load_dataset # Load the free 400-row sample directly from HuggingFace Hub ds = load_dataset( "wirthal1990-tech/USDA-Phytochemical-Database-JSON", split="sample", trust_remote_code=False ) df = ds.to_pandas() print(f"Records: {len(df)} | Columns: {list(df.columns)}") df.head() ``` > **Note:** The `split="sample"` loads `ethno_sample_400.json` (400 rows, 8 columns). > The full 104,388-row dataset is available at [ethno-api.com](https://ethno-api.com). ## Sample Record Below is a real record from the dataset โ€” QUERCETIN, one of the most-studied plant compounds: ```json { "chemical": "QUERCETIN", "plant_species": "Abelmoschus esculentus", "application": "5-Lipoxygenase-Inhibitor", "dosage": "IC50 (uM)=4", "pubmed_mentions_2026": 31310, "clinical_trials_count_2026": 847, "chembl_bioactivity_count": 4231, "patent_count_since_2020": 312 } ``` All 8 fields are populated for all 104,388 records in the full dataset. The free 400-row sample contains real values for `pubmed_mentions_2026`; the three enrichment fields (`clinical_trials_count_2026`, `chembl_bioactivity_count`, `patent_count_since_2020`) contain representative placeholder values pending completion of the full enrichment run. ## File Manifest | File | Size | Format | Access | |------|------|--------|--------| | `ethno_sample_400.json` | 67 KB | JSON | Free (this repo) | | `ethno_sample_400.parquet` | 15 KB | Parquet | Free (this repo) | | `ethno_dataset_2026_v2.json` | ~18 MB | JSON | [Commercial (โ‚ฌ699)](https://ethno-api.com) | | `ethno_dataset_2026_v2.parquet` | ~900 KB | Parquet | [Commercial (โ‚ฌ699)](https://ethno-api.com) | | `MANIFEST_v2.json` | ~1 KB | JSON | Included with purchase | | `quickstart.ipynb` | 6 KB | Notebook | Free (this repo) | ## Data Sources & Methodology | Source | Access | Date | Method | |--------|--------|------|--------| | [USDA Dr. Duke's Phytochemical and Ethnobotanical Databases](https://phytochem.nal.usda.gov/) | Public domain | 2026 | Full 16-table PostgreSQL import, normalized | | [NCBI PubMed](https://pubmed.ncbi.nlm.nih.gov/) | E-utilities API | March 2026 | `esearch` per compound, total publication count | | [ClinicalTrials.gov](https://clinicaltrials.gov/) | v2 API | March 2026 | Study count per compound name | | [ChEMBL](https://www.ebi.ac.uk/chembl/) | REST API (v34) | March 2026 | Bioactivity measurement count via molecule search | | [USPTO PatentsView](https://patentsview.org/) | REST API v1 (`search.patentsview.org/api/v1/patent/`) with `X-Api-Key` header, querying US patent counts since 2020-01-01 | March 2026 | US patents since 2020-01-01 mentioning compound | All enrichment scripts are deterministic, checkpoint-resumable, and respect API rate limits. Source code available upon request for enterprise customers. ## Use Cases - **RAG Pipelines** โ€” Ground LLM responses with verified phytochemical data. Each record has a PubMed evidence score โ€” use it to weight retrieval results and filter hallucinations. - **Drug Discovery** โ€” Prioritise natural product leads by combining PubMed citations, clinical trial presence, ChEMBL bioactivity depth, and patent landscape. One query replaces weeks of manual lit review. - **Market Intelligence** โ€” Patent density score reveals which compounds are attracting commercial investment. Cross-reference with clinical trials to identify underexplored compounds with IP whitespace. - **Academic Research** โ€” Pre-computed evidence scores save months of PubMed searching. The BibTeX citation block below makes this dataset citable in peer-reviewed publications. ## Dataset Versions | Version | Records | Schema | Status | |---------|--------:|--------|--------| | v1.0 | 104,388 | 5 columns (USDA baseline) | Deprecated | | **v2.0** | **104,388** | **8 columns (+ PubMed, ClinicalTrials, ChEMBL, Patents)** | **Current** | The free sample (`ethno_sample_400.json`) uses the v2.0 schema. Enrichment fields contain representative values pending completion of the full enrichment pipeline. ## License & Commercial Access - **Free 400-row sample**: [CC BY-NC 4.0](https://creativecommons.org/licenses/by-nc/4.0/) โ€” use for evaluation, academic research, and prototyping. - **Full 104,388-row dataset**: Single-entity commercial license, **โ‚ฌ699 one-time purchase** at [ethno-api.com](https://ethno-api.com).
