The present invention addresses the problem of providing a cytochrome P450 protein by identifying a gene of a Cupressaceae plant involved in the biosynthesis of ferruginol and encoding the cytochrome P450 protein with said gene. The present invention also addresses the problem of providing a new method for producing ferruginol on the basis of said gene.　Provided is a cytochrome P450 protein of an isolated CYP720 family or an active fragment thereof, the protein having an activity of oxidizing the carbon at position 12 of an abietane-type diterpene. The cytochrome P450 protein or an active fragment thereof is derived from a plant selected from the group consisting of Cupressaceae, Taxaceae, Cephalotaxaceae, Podocarpaceae, and Araucariaceae.

The invention relates to the technical field of natural product separation, in particular to a mataidane type diterpenoid compound separated from a pinus massoniana cone and a preparation method and application of the mataidane type diterpenoid compound. The masson pine cone is subjected to alcohol extraction, resin adsorption and column separation to obtain the mataidane diterpenoid compound. The podocarpus macrophyllus type diterpenoid compound disclosed by the invention can be used for resisting inflammation, and the podocarpus macrophyllus type diterpenoid compound has certain inhibitory activity on RAW264.7 cells.

This invention discloses a plant extract compound antibacterial agent and its application in feminine hygiene products. The raw materials of this plant extract compound antibacterial agent, by weight percentage, include 0.5%~5% antibacterial agent and 0.5%~30% synergistic agent; wherein the antibacterial agent is selected from Magnolia officinalis extract, and the synergistic agent is selected from at least one of Cypress twig extract and Podocarpus macrophyllus extract. This plant extract compound antibacterial agent, by combining the above-mentioned antibacterial agent and synergistic agent, can further broaden the antibacterial spectrum, compensate for the insufficient inhibitory effect of single plant extracts on specific strains, enhance the stability of active ingredients, reduce the risk of activity degradation due to pH and temperature changes during product storage and use, and distinguish itself from chemically synthesized and inorganic antibacterial agents. Its mechanism of action is gentle, inhibiting pathogenic bacteria and effectively maintaining the microecological balance of the feminine hygiene area, avoiding problems such as mucosal dryness and sensitivity caused by long-term use.
