What are the effects and functions of Alpinia oxyphylla

Many people are not familiar with Alpinia oxyphylla. It is a Chinese medicinal material. Alpinia oxyphylla is commonly used in clinical practice. The reason why Chinese medicine is popular is that it has few side effects and good health-preserving effects. The same is true for Alpinia oxyphylla. The medicinal effects and functions of Alpinia oxyphylla are very obvious.

1. Inhibition of prostaglandin synthesis

Experiments show that the methanol extract of the fruit of the schizophylla has the effect of inhibiting the activity of prostaglandin synthase. The concentration of schizophylla ketone A that inhibits prostaglandin synthase by 50% is 0.51umol.

2. Effects on the heart

The methanol extract of Alpinia oxyphylla has the activity of enhancing the contractility of the left atrium of guinea pigs, and its minimum effective dose is 10-6g/ml. The reporter believes that the cardiotonic effect of phenoxyethanol is partly due to its inhibition of the sodium-potassium pump in the myocardium.

3. Calcium antagonism and effects on blood vessels

The methanol extract of the fruit of the Chinese ginseng has an antagonistic effect on the activity of calcium in the rabbit's aorta. Its active ingredient is ginseng alcohol. At a dose of 3×10-5mol, ginseng alcohol has a significant inhibitory effect on the contraction of the aorta caused by potassium chloride, but has no effect on the contraction caused by norepinephrine.

4. Inhibit ileal contraction and anti-cancer effects

The water extract and ethanol extract of Alpinia oxyphylla have an inhibitory effect on the ileal contraction of guinea pigs induced by histamine and barium chloride; the water extract has moderate activity in inhibiting the growth of sarcoma cells and no toxicity was observed.

5. Effects on metabolism

Reports indicate that the compound preparation of Alpinia oxyphylla kernel, "Alpinia oxyphylla syrup", can improve energy metabolism and promote the synthesis of CA substances and cAMP. Animal experiments have shown that this preparation can increase the levels of NE, DA, cAMP in the mouse brain and plasma cAMP, and has the function of increasing memory and enhancing immunity.

6. Improvement of learning and memory disorders

Yizhi No. 1 (composed of Polygonum multiflorum, Acorus calamus, Pueraria lobata, Ginkgo biloba, Ligusticum chuanxiong, Paeonia lactiflora, etc.) has an improving effect on the learning and memory disorders of mice caused by five different chemical drugs. Oral administration of 25g/kg and 50g/kg Yizhi No. 1 to mice for 7 days antagonized the destructive effects of 0.001g/kg scopolamine and 0.03g sodium pentobarbital on memory acquisition, improved the poor memory consolidation caused by 0.2g/kg chloramphenicol and 0.12g/kg sodium nitrite, and improved the memory loss caused by 40% ethanol. There was no significant difference compared with the Naofukang control group.
