Isoflavones from Psorothamnus arborescens via high-throughput natural product chemistry methods

One new isoflavone, arborestin (2), together with the known fremontin (1), were obtained from Psorothamnus arborescens via high-throughput natural product chemistry methods. The isoflavones were isolated and the structure elucidation was performed using a capillary scale NMR probe and HR-/LR-ESIMS data.
