1. Anti-osteoporosis and promote fracture healing

Studies have shown that the chloroform extract layer of 60% ethanol crude extract of elderberry has a significant effect on the repair of bone density, and contributes to the bone growth and bone content of the femur and tibia, and increases the tibial diaphysis of ovariectomized mice. Biomechanical strength is the most effective ingredient to promote the proliferation and differentiation of osteogenic UMR106 cells.

2. Anti-inflammatory and analgesic

Using the hot plate method, 20 g·kg-1 of elderberry decoction was administered to the mice. The results showed that the mice were in a quiet state after taking the medicine, which showed that it had analgesic effect on mice. morphine. The water extract of elderberry stems and branches has a significant inhibitory effect on the writhing response induced by acetic acid in mice and the increase in the permeability of abdominal capillaries in mice, suggesting that elderberry stems and branches have obvious analgesic and anti-inflammatory effects.

3. Anti-bacteria and virus

The results show that larchyl alcohol isolated from the methanolic extract of elderberry stems and branches exhibits its antifungal activity by interfering with the cell membrane of fungi, and may be used as a novel antifungal agent for the treatment of human fungal infections.

4. Anticancer effect

Oral administration of 2000 mg/kg elderberry oil to mice can inhibit the growth of S1Chemicalbook80 tumor-bearing solid tumors in mice and H22 liver cancer solid tumors in mice. The life extension rate is greater than that of cyclophosphamide. It is indicated that elderberry oil has a certain anticancer effect.

5. Improve learning and memory ability

Elderberry oil can significantly improve the memory acquisition disorder caused by scopolamine in mice, the memory consolidation disorder caused by chloramphenicol and the memory reproduction disorder caused by 40% ethanol in the platform jumping method and water maze test, indicating that its It can improve the ability of learning and memory, and its improvement effect is equal to or better than that of Naofukang.

6. Anti-AIDS

When the IC50 of elderberry extract is 0.017g/L, it can inhibit HIV-1 reverse transcriptase, indicating that it has anti-AIDS activity.

7. Blood lipid lowering effect

Studies have shown that elderberry oil gavage significantly reduces total cholesterol, low-density lipoprotein and arteriosclerosis index in hyperlipidemia model mice and chickens, and can also reduce triglycerides. Increases HDL and HDL/total cholesterol ratios. The results suggest that elderberry oil has obvious hypolipidemic and anti-arteriosclerotic effects, and its hypolipidemic and anti-arteriosclerotic effects are better than Maitong.
