    Abstract: The present invention related to method for the mass separation of magnolol from Magnoliae cortex or Magnoliae radix. The method comprises the steps of: 1) crushing Magnoliae cortex or Magnoliae radix, extracting the crushed material with organic solvent, adding n-hexane to the extract so as to obtain a n-hexane layer; 2) concentrating the n-hexane layer in a water bath at a temperature of 30-40° C. and a revolution speed of 40-200 RPM under reduced pressure so as to form a crude crystal; and 3) removing the n-hexane from the crude crystal, completely dissolving the crude crystal in chloroform, adding n-hexane to the n-hexane-containing solution, and leaving the solution to stand at room temperature so as to recrystallize the solution. In the method, a column chromatography step which is necessarily carried out in the general separation process is omitted so that separation process steps are reduced, leading to a saving in separation time. Also, expensive equipment is not required, leading a reduction in separation cost. Accordingly, the method is effective for the mass separation of expensive magnolol.

    Abstract: An orthogonal frequency division multiplexing (OFDM) transmission/receiving system, and a block encoding method therefor, are provided. The OFDM transmission system includes a block encoder for encoding binary data of U length into V-ary data expressed in a group of n bits according to a predetermined mapping rule, a serial-to-parallel converter for converting the V-ary data into parallel data, a V-ary modulator for V-ary modulating V-ary data received in parallel to generate an orthogonal frequency division multiplexing (OFDM) symbol having U sub-symbols, and a transmitter for post-processing the OFDM symbol so that the OFDM symbol is suitable for telecommunications and transmitting the resultant OFDM symbol. In this method, Q-ary data is block encoded and Q-ary modulated to reduce the ratio of the peak power to the average power of an OFDM signal when it is transmitted, so that the OFDM signal can be transmitted at a high data transmission rate as compared to the prior art in which binary data is block encoded.
