Problems solved by technology

Finasteride is currently a 5α-reductase inhibitor widely used clinically. It has high safety and is well tolerated by patients. However, there are still some adverse reactions, mainly caused by the decrease of DHT level, including impotence or ejaculation. Failure, loss of libido, feminized breasts, and related symptoms
[0004] Cardamom is the fruit of Alpinia galanga Willd., a plant of the Zingiberaceae family. It is mainly produced in Guangdong, Guangxi, Yunnan and other places. It is pungent and warm, and it belongs to the spleen and stomach meridian. Cold pain, food accumulation, vomiting and diarrhea, etc. ("Clinical Chinese Materia Medica", edited by Zhang Tingmo, China Press of Traditional Chinese Medicine, 2004, 8). Modern pharmacological research shows that: the components isolated from the methanol extract of red cardamom seeds Intraperitoneal injection can significantly inhibit rat ulcers; the volatile oil of its rhizomes shows antimicrobial activity, can resist Gram-positive bacteria, yeast and some skin fungi, and has cytotoxicity and antifungal activity; The ingredients have anti-tumor effects (Volume VIII of "Chinese Materia Medica", Shanghai Science and Technology Press, 1999). But so far, there have been no reports that cardamom inhibits 5α-reductase, prevents or treats benign prostatic hyperplasia and related diseases.

Embodiment 1

[0025] The preparation of embodiment 1 red cardamom crude drug medicine

[0026] Take the original drug of red cardamom, that is, the dried and mature seed kernel of Alpinia galanga Willd. After purification, crush and sieve according to the conventional method, make red cardamom fine powder with a particle size of 60-80 mesh, sterilize, and pack Serve.

Embodiment 2

[0027] The preparation of embodiment 2 cardamom extract

[0028] Weigh 1000g of cardamom, extract three times with 90% ethanol, the amount of solvent is 8 times, 6 times, 6 times respectively, and the extraction time is 2 hours, 1 hour, 1 hour respectively. Combine the extracts and recover until there is no alcohol smell. Dry under reduced pressure at 50°C to obtain sample A. Weigh 50g of sample A and dissolve it with 150ml of distilled water. The aqueous solution was extracted with petroleum ether, diethyl ether, ethyl acetate, and n-butanol respectively with 3 times the volume, and the solvent was recovered under reduced pressure to obtain samples B (petroleum ether phase), C (ether phase), D (ethyl acetate phase), and E ( Butanol phase), F (water phase). The above-mentioned extraction solvents can be selected and used in combination with different organic solvents as required.

Embodiment 3

[0030] Weigh 1000 g of cardamom, extract three times with 30% ethanol, the amount of solvent is 8 times, 6 times, 6 times respectively, and the extraction time is 2 hours, 1 hour, 1 hour respectively. Combine the extracts and recover until there is no alcohol smell. The red cardamom extract was invented by drying under reduced pressure at 50°C.
