1. The kava-pyrones kawain and dihydromethysticin are constituents of Piper methysticum which exert anticonvulsant, analgesic and anxiolytic properties. 2. In the present study the effect of these kava-pyrones were tested on field potential changes (fp) induced by omission of the extracellular Mg2+,

Melanogenesis stimulation activity of aqueous ethanolic extracts obtained from several different parts of five Piper species, namely Piper longum, P. kadsura, P. methysticum, P. betle, and P. cubeba, were examined by using cultured murine B16 melanoma cells. Among them, the extract of P. methysticum

Three kava lactone constituents of Piper methysticum, namely, kawain, methysticin and desmethoxyyangonin, have been separated and identified by reversed-phase HPLC using superheated deuterium oxide as the mobile phase and on-line 1H-NMR detection. The method avoids the use of organic solvents in the
