Natural Products Repository

DTP’s Natural Products Repository is the world’s largest storehouse of natural products. It houses close to 170,000 extracts from samples of more than 70,000 plants and 10,000 marine organisms collected from more than 25 countries, plus more than 30,000 extracts of diverse bacteria and fungi. The natural products stored in DTP’s repository are screened against the NCI human tumor cell line assay for potential anticancer activity shortly after their collection. So far, about 4,000 natural-source extracts have shown in vitro activity against human cancer cells, making them worthy of further study by DTP researchers.

The Natural Products Repository, administered by the Natural Products Branch, provides extramural researchers with natural products extracts for testing against any human disease.
