A strategy for enrichment of the bioactive sphingoid base-1-phosphates produced by Hypericum perforatum L. in a balloon type airlift reactor

► An efficient enrichment for sphingoid base-1-phosphates from Hypericum perforatum culture. ► Profiles of sphingoid base-1-phosphates in H. perforatum culture were obtained. ► Strong correlation of sphingoid base-1-phosphates and growth rate was observed.
