Extract Library 18 April 2016 Jan Pen Centre of Expertise for Plant Compounds
Background The Extract Library was set-up to provide a bridge between the huge biodiversity in plant compounds in Dutch horticultural crops and applications of those crops in high-value non-traditional markets
Market Diverse market segments with a common need for novel products Pharmaceuticals Agro(chemicals) Natural colours, flavours and fragrances Cosmetics & toiletry Herbal medicines Food supplements Feed additives Fine chemicals
Market need • Biodiversity plant compounds • Information on cultivars and plant material – Taxonomy, known compounds, (traditional) use, edibility, toxicity etc. • Reproducible supply • Cultivation without chemicals • Compliance with regulatory requirements
Extract Library
Crops • Huge diversity in plant types • Families: 205 • Genera: 927 See list • Species: 1,300 • Huge diversity in plant compounds • Estimate: 100,000 – 200,000 • Can be grown in The Netherlands (or elsewhere) • Controlled and reproducible cultivation • Reproducible composition and amount of plant compounds • No chemical crop protection products used • No false positives

Screening Extract Library
Screening results - I – Pharmaceutical • HTS in an anti-inflammatory activity assay – Cleaned extracts (960) in DMSO; 384-well format – A number of hits - to be validated • Anti-mycobacterium activity (TBC) – Cleaned extracts (320) in ethanol; 384-well format – One hit - to be validated
Screening results - II – Agrobiological • Activity against an important agricultural fungal disease – Cleaned extracts (960) converted to 96-well format in DMSO – Crude extracts (320) in 96-well format converted to DMSO – Several hits - to be validated – Food • Activity against an important food spoiling fungus – Cleaned extracts (960) converted to 96-well format in DMSO – Crude extracts (320) in 96-well format converted to DMSO – Several hits - to be validated
