„Decoctions of the root and stem bark of Ptychopetalum olacoides Benth., Olacaceae, have been used in folk medicine for their aphrodisiac, appetite modulator and anti-tremor properties. Additionally, the plant is claimed to act as a nerve tonic by promoting recovery of cognitive and motor functions after brain injuries (including strokes) and cognition improvement (particularly alertness and memory) in the elderly.
… HPLC-UV/PAD profiles of bark and commercial extracts of P. olacoides were examined, and a protocol for the isolation and purification of three compounds present in all of the analysed extracts was elaborated. The common components were identified by NMR as vanillic acid, protocatechuic acid and theobromine, the former of which has been proposed as a phytochemical marker for P. olacoides.“
