Embodiment 1

[0016] Embodiment 1 (preparation of golden pine bisflavone)

[0017] Collect 5 kg of dried Chinese fir branches and leaves, crush them, and extract them ultrasonically for 3 times with 95% ethanol. The extracts are combined, concentrated under reduced pressure, degreased by petroleum ether ultrasonically, then extracted with ethyl acetate, filtered, and the ethyl acetate extracts are decompressed and concentrated , dried to obtain the crude extract, the ethyl acetate crude extract was subjected to silica gel column chromatography 1400g (particle size 200-300 mesh, 10cm×20cm), petroleum ether-ethyl acetate (1:9~1:5) gradient elution , tracked and detected by TLC, combined, the eighth fraction was decompressed, concentrated to dryness, and rinsed with methanol to remove impurities. After vacuum drying, the golden pine bisflavone yellow powder was obtained, which was detected by HPLC with a purity greater than 95%, and was used for subsequent in vivo and in vitro pharmacological ...

Embodiment 2

[0018] Embodiment 2 (the effect of pine bisflavone on osteosarcoma cell MG-63-PERE)

[0019] Cells: Osteogenic sarcoma cells MG-63-PERE stably transfected with the estrogen response element as the promoter and firefly luciferase as the reporter gene provided by the School of Pharmacy, Second Military Medical University of the Chinese People's Liberation Army.

[0020] Experimental process: plate 5000 cells per well on a 96-well plate, add medicine (DMSO concentration < 2%) after the cells adhere to the wall, remove the supernatant after culturing in the incubator for 6 hours, wash with ice-cold PBS, add 20 μl of cell lysate is ready for use.

[0021] Detection method: measure on a chemiluminescence detector, use a dual reporter gene detection system, first measure the luminescence of firefly luciferase, and then quench to measure the luminescence of the internal standard Renilla luciferase.

[0022] Experimental results: the results are represented by the percentage of the am...

Abstract

The invention relates to the application of the biflavone of golden pine in the preparation of medicine and food for preventing and treating osteoporosis. Pharmacological studies in vitro and in vivo have shown that amiflavonoids have estrogen-like effects and can significantly increase femur stock density, bone ash weight, bone calcium content and bone phosphorus content in rats with osteoporosis caused by retinoic acid, and have significant prevention and treatment of osteoporosis. role, and has application prospects in the preparation of drugs for the prevention and treatment of osteoporosis.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a new medical application of aquinone. Background technique [0002] Osteoporosis is a metabolic bone disease characterized by decreased bone mass and destruction of bone microarchitecture, leading to increased bone fragility and susceptibility to fractures. The disease mainly occurs in the elderly and postmenopausal women. With the arrival of an aging society, the incidence of this disease is increasing year by year. There are about 90 million osteoporosis patients in my country. Anti-osteoporosis drugs have a very broad market prospect. The research and development of indication drugs is one of the hot spots in the research and development of new drugs. [0003] Existing studies have shown that the pathogenesis of osteoporosis lies in the process of bone formation, the main function of osteoclasts is to remove damaged debris and form bone holes, and the main role of osteoblast...
