  • Publication number: 20170274026
    Abstract: A method of making triterpenoids from petri dish cultured Antrodia cinnamomea includes: A. providing petri dish cultured Antrodia cinnamomea in an extracting container; B. providing a supercritical solvent to the extracting container to obtain an Antrodia cinnamomea extract; sending the Antrodia cinnamomea extract to a chromatographic column to separate impurities and triterpenoids from the Antrodia cinnamomea extract, and removing the impurities, and collecting the triterpenoids containing fraction; and C. testing the bioactivity of the triterpenoids containing fraction by cytotoxicity test, cell morphology analysis, cell cycle and apoptosis test, and cell motility test to find an anti-cancer effect of the triterpenoids.

  • Publication number: 20170226042
    Abstract: A method of making artepillin C in propolis includes the following steps: A. Mix propolis with ethanol to obtain a propolis-ethanol extract; B. Provide supercritical carbon dioxide and the propolis-ethanol extract to a chromatographic column to separate wax and artepillin C, and then remove the wax at a bottom of the chromatographic column and collect the artepillin C containing isolate at a top of the chromatographic column; and C. Test the artepillin C by a cytotoxicity test, a cell morphology analysis, a cell cycle and apoptosis test, and a cell motility metastasis test to find an anti-cancer effect of the artepillin C containing isolate.
