| titleOfInvention | A kind of ginkgo leaf flavonoid extract and its preparation method and feature map construction method |
| abstract | The invention provides a ginkgo leaf flavonoid extract and its preparation method and characteristic map construction method. The medicinal components of the ginkgo leaf flavonoid extract are composed of the following parts: the content of myricetin-3-O-rutinose is 3% to 6% (w /w), Myricetin‑3‑O‑Glucose 3%～6% (w/w), Rutin 8%～11% (w/w), Tagetin‑3‑O‑Rutinose 5%～7 %(w/w), quercetin‑3‑O‑rutinose 5%～7% (w/w), kaempferol‑3‑O‑rutinose 6%～9% (w/w), iso Rhamnetin‑3‑O‑Rutinose 6%～10% (w/w), Quercetin‑2”‑(6”‑p-Cinnamoyl Glucosyl) 13%～15% (w/w), Kaempferol-3-(6”'-p-cinnamoyl glucosyl-rhamnoside) 11%～15% (w/w). The flavonoid extract is obtained by separating Ginkgo biloba extract twice through a polyamide column , can be used as an antioxidant in food, medicine, and health products. The invention solves the problem of unknown effect components of ginkgo leaf flavonoids extract, reduces the difficulty of quality control, and the established ultra-high performance liquid phase characteristic map has specificity for quality detection. |
