The GPE includes know-how in ethnobotany, botany, pharmacology, pharmacognosy, organic chemistry and analytical chemistry to present a variety of extracts as wide as possible. The selection procedure is based on biotope and taxonomic diversity. Moreover, a “patentability” criteria is added to ensure the originality of the selected plants. Each plant is stocked so that resupply is possible within a short delay.

Library Technical Characteristics:

GPE is presented in a format suitable for HTS. A microplate contains 80 extracts representing 20  plants, each of them being represented by 4 different polarity solvent fractions. Each well includes 2 mg of extract diluted in 200 µL of DMSO. This high concentration easily allows dilutions in order to avoid the side toxicity effect of DMSO.
