| titleOfInvention | Method for preparing ginkgo leaf flavonoid dimer and its stabilization method |
| abstract | The present invention relates to a method for producing dimeric flavonoids from ginkgo biloba, which can be used as a raw material for cosmetics or medicines, and to a method of stabilizing the same, in particular, 80 to 100% methanol or 70 to 95 The dried product extracted, filtered and evaporated to dryness with% ethanol or chloroform-methanol mixture (5: 1 to 1: 2) was selectively dissolved in the solvent, and then transferred to a Sephadex column (Sephadex LH-20, Pharmacia), and again, selective. After eluting with the solvent, only the fractions containing the flamonoid dimer in the eluate were collected and evaporated to dryness to produce purified extracts having a high content of flavonoid dimers. Daylight, by dissolving in aliphatic alcohols or esters of lower alcohols and saturated fatty acids FIG such relates to a method for stabilizing without the oxidative decomposition and discoloration on aging. |
