Embodiment 1
[0010] 30 kg of stems and branches of elderberry (Sambucus Williamsii Hance) were crushed and extracted twice under reflux with 8 times the amount of 60% ethanol for 2 hours each time. The extracts were combined, and the solvent was evaporated under reduced pressure to obtain 900 g of ethanol extract. For this extraction, pure ethanol and pure methanol can also be used instead of 60% ethanol.
[0011] 350 grams of ethanol extract are used in Example 2. 550 grams of ethanol extract was suspended in 4000 milliliters of water and extracted 3 times with equal volumes of chloroform, ethyl acetate and n-butanol, and the solvent was evaporated under reduced pressure to obtain 100 grams of chloroform extract and 30 grams of ethyl acetate extract. Butanol extract 70 grams, water extract 330 grams. Methyl acetate and butyl acetate can replace ethyl acetate, and isopropanol can replace n-butanol.
[0012] The aqueous suspension of ethanol extract can also be directly extracted with et...
Embodiment 2
[0015] The in vivo bioactivity test results of the elderberry ethanol extract obtained from Example 1 are described.
[0016] Three-month-old female SD rats were randomly divided into 5 groups, 4 groups with ovariectomy and 1 group with sham operation. The rats in the ovariectomized group (OVX) were anesthetized with ether and had their bilateral ovaries removed. The rats in the sham operation group (Sham) were also anesthetized with ether, but the ovaries were not removed, and only a little fat outside the ovary was cut off. One month after the operation, the ethanol extract of elderberry was dissolved in distilled water to prepare two concentrations of 600mg / ml and 300mg / ml, and the positive control drug 17β-estradiol was suspended in distilled water, and administered by intragastric administration respectively. The model control group and the sham operation group were given the same volume of distilled water. The administration continued for 3 months, and the body weight o...
Embodiment 3
[0084]Illustrate that the Elderberry chloroform extract obtained from Example 1, the ethyl acetate extract obtain and identify 12 lignan compounds through silica gel column chromatography, molecular sieve chromatography, ODS column chromatography and high performance liquid phase , 4 phenolic acid compounds (including their derivatives), new uses for the treatment of osteoporosis. emodin (emodin, compound 1), betulin (betulin, compound 2), betulinic acid (betulinic acid, compound 3), vanillin (vanillin, compound 5), coniferaldehyde (compound 7), (-)-lirioresinol C ( Compound 10), (-)-diapinoresinol (Compound 11), 1-(4-hydroxy-3-methoxyphenyl)-2-(4-hydroxy-3-methoxyphenyl)-1,3-propanodiol (Compound 12), guaiacylglycerol- β-O-4′-coniferyl ether (compound 13), (-)-erytheo-1-(4-hydroxy-3-methoxy--phenyl)-2-(4-hydroxypropyl-2-methoxyphenoxy)-1,3 -propanodiol (compound 15), (-)-threo-1-(4-hydroxy-3--methoxyphenyl)-2-(4-hydroxypropyl-2-methoxyphenoxy)-1,3-propanodiol (compound 16), ...
