The invention discloses a lindera glauca extract, a preparation method thereof and application of the lindera glauca extract in preparation of drugs for preventing and / or treating rheumatoid arthritis. The research finds that the lindera glauca extract can obviously reverse arthritic rat plantar part swelling and toe bending, relieve ankle joint injury, relieve synovial hyperplasia and inflammatory cell infiltration, inhibit joint fusion, relieve joint gap stenosis, relieve articular surface fusion tendency, increase bone mineral density and bone trabecula number, reduce bone trabecula separation degree and improve joint fusion. The lindera glauca extract can be used for relieving rheumatoid arthritis by protecting the inherent structure of joint tissues and improving inflammation, so that a novel natural medicine choice is provided for preventing and / or treating rheumatoid arthritis.

The application discloses a submerged Cinnamomum micranthum in-vitro rapid propagation and brown-preventing seedling raising method based on zygote embryos, directly induces adventitious buds of the submerged Cinnamomum micranthum for the first time, significantly improves a propagation coefficient, and overcomes problems such as vitrification and browning of the adventitious buds of the submerged Cinnamomum micranthum. The application establishes an efficient and stable in-vitro regeneration system of the submerged Cinnamomum micranthum, and provides a basis for large-scale seedling raising of the submerged Cinnamomum micranthum.

The present invention discloses sesquiterpene compounds, a preparation method thereof and applications in the field of anti-tumor, belonging to the technical field of pharmaceutical compounds. The preparation method of the sesquiterpene compounds is as follows: (1) Take dry roots of Lindera glauca, slice them, add ethanol for extraction to obtain an extraction solution, combine the extraction solutions and concentrate to obtain an extract, and use petroleum ether to extract the extract to obtain a crude extract; (2) Purify the crude extract by normal-phase silica gel column chromatography, normal-phase silica gel column chromatography, reverse-phase silica gel column chromatography and semi-preparative HPLC to prepare the sesquiterpene compounds from the crude extract. The sesquiterpene compounds have certain anti-tumor activities and have good application prospects in the field of anti-tumor.

The invention discloses a firming and anti-wrinkle composition as well as a preparation method and application thereof, and the firming and anti-wrinkle composition comprises the following components in parts by mass: 0.2-0.5 part of a growth factor accelerant, 1 part of a lindera glauca fruit extract and 0.02-0.08 part of salmon essence source DNA (deoxyribonucleic acid) sodium. The growth factor accelerant is selected from at least one of hydroxyl pinacolone retinoate, bakuchiol, a spanishneedles herb extract, asiaticoside, palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7. The growth factor accelerant, the lindera glauca fruit extract and the salmon essence source DNA sodium cooperate to improve the problems of skin laxity and slowdown epidermal layer cell renewal caused by deep protein loss and wrinkle formation caused by decline of the stratum corneum moisturizing capacity, and the effects of tightening and resisting wrinkles are synergistically exerted in multiple aspects.

The present invention relates to a pharmaceutical composition and a health functional food for the prevention or treatment of thrombosis containing an extract of Lindera glauca Blume, and more specifically, to a pharmaceutical composition and a health functional food for the prevention or treatment / improvement of thrombosis through inhibition of blood coagulation containing, as an active ingredient, a hot water extract of Lindera glauca Blume leaves having potent thrombin inhibitory and blood coagulation factor inhibitory activity. The extract of *Lindera glaucaBlume*, used as an active ingredient in the pharmaceutical composition and health functional food for the prevention or treatment of thrombosis according to the present invention, exhibits excellent antithrombotic activity through strong inhibition of thrombus-related enzymes such as thrombin and blood coagulation factors. At the same time, it does not exhibit any hemolytic activity against human red blood cells, has excellent thermal stability, and does not show loss of blood coagulation factor inhibitory effects or thrombus-related enzyme inhibitory effects even under acidic conditions of pH 2 and in plasma. Therefore, it is expected to be usable for the prevention and treatment of thrombosis, such as ischemic stroke and hemorrhagic stroke, through the improvement of blood circulation. Furthermore, since the active ingredient has the excellent effect of being processed into various forms such as extract, powder, pills, and tablets, allowing for formulation into a form suitable for regular consumption, this invention is highly useful for the pharmaceutical and food industries.
