  • Patent number: 11092590
    Abstract: A method for measuring blood glucose levels by a portable terminal using a strip module is provided. The strip module includes a dye pad having a color that changes in response to a sample applied to the dye pad. The strip module also includes a transparent strip having a first side and a second side. The first side is opposite the second side. The dye pad is mounted on the first side of the transparent strip, and the transparent strip reflects light provided from a light source of a portable terminal located adjacent to the second side and transmits the light to the dye pad.

  • Patent number: 5900367
    Abstract: The present invention relates to a rapid and simple method for mass production of taxol from the cell culture of Taxus genus plant with a high purity and recovery. The method for mass production of taxol from Taxus genus plant of the present invention, comprises the steps of: (i) organic solvent extraction of biomass from Taxus genus plant to obtain a crude extract; (ii) synthetic adsorbent treatment of the crude extract and filtration to give filtrate; (iii) addition of hexane to the filtrate to precipitate crude taxol; (iv) fractional precipitation of the crude taxol in a mixture of alcohol and water and vacuum drying the precipitate to obtain taxol powder; and, (v) high performance liquid chromatography of the taxol powder. According to the method of the present invention, taxol of over 99% purity can be simply obtained from Taxus genus plant with a high recovery of over 90%.
