Abstract

The invention discloses a synthetic method of a ginkgo leaf polyprenol metal complex with light-operated activity. The method comprises the following steps: taking high-purity ginkgo leaf polyprenol as a raw material, replacing terminal hydroxyl of polyprenol with an active group with stronger coordination ability by a chemical modification means, and then carrying out complexation reaction with aruthenium polypyridine complex to synthesize the ginkgo leaf polyprenol-ruthenium polypyridine metal complex. The prepared complex has good photoinduced dissociation efficiency and light-operated anti-tumor performance, and can provide theoretical reference and technical support for development of high-valued ginkgo leaf polyprenol functional products.

Description

technical field

[0001] The invention belongs to the field of high-value functional product development of natural products, and in particular relates to a synthesis method of ginkgo biloba polyprenol metal complex with light control activity. Background technique

[0002] Ginkgo biloba is a precious and unique forest source plant in my country. Ginkgo biloba has many important pharmacological effects and economic value, among which the main bioactive components are compounds such as flavonoids, terpene lactones, polyprenols (PPs) and polysaccharides. At present, the development and application of ginkgo biloba products in my country are still in the initial stage, and the flavonoids and terpene lactones are mainly used. The most valuable PPs have not yet been developed and utilized. Ginkgo biloba polyprenol (GBP) is a betulinic alcohol PPs composed of 14-24 isopentenyl units. It has become a research hotspot in recent years because of its similar structure to dolichol, whic...
