Prostate enlargement is a benign tumor commonly seen in middle-aged men in their 40s and 50s. The prostate enlarges, pushes the posterior urethra, increases resistance to urinary flow, and results in difficulty in urinating. It is one of the most common diseases occurring in middle-aged men and usually starts in their 40s, 50% of their fifties, 60% of their 60s and 70% of their 70s have enlarged prostates. As the elderly population increases, Of the total population.

In order to treat the enlargement of the prostate, sympathetic blockers for relieving the tension of the smooth muscle of the prostate gland, an anti-male hormone agent for inhibiting the abnormal proliferation of the prostate gland epithelium, and a 5α-reductase inhibitor, It has been used for preventive purposes. However, sympathomimetic blockers lower blood pressure, so they are limited in patients with hypotension. In the process of artificially controlling the nerves, bowel movements may be reduced to cause constipation or chronic fatigue. In addition, anti-male hormone agents may cause side effects such as loss of sexual desire, erectile dysfunction, and the like.

Finasteride is a representative 5a-reductase inhibitor, marketed under the trade name Proscar or Propecia. Finasteride inhibits the production of DHT (Dihydrotestosterone), which reduces the activity of the prostate in the prostate and reduces the prostate weight and volume, thereby inhibiting the progression to benign prostatic hyperplasia and reducing the risk of developing prostate cancer (Robaire B et al., 2006, Molecular and Cellular Endocrinology, 250 (1-2): 190-5).

Due to the superiority of such effects, the development of related art using a pinastellite such as a novel production method of high-purity pinasteride (Korean Patent No. 0483136) and a composition for treating hair loss including polymerized pinasteride nanoparticles (Korea Patent Publication No. 2015-0046332) . However, the adverse effects of increasing the incidence of breast cancer in men and causing sexual dysfunction have been reported and require caution in use (Medlaines and Healthcare products Regulatory Agency Drug Safety Update, 2009; Mella JM et al., 2010), Archives of Dermatology 146 (10): 1141-50.).

Manufacturing example  1. Preparation of extract

Manufacturing example  1-1. Production of Eucalyptus extract

Morus alba (Scientific name: Morus alba Linne, Mori Radicis Cortex) was prepared as follows. Commercially available cornflakes were obtained and pulverized, and then 10 L of 70% ethanol was added to 1 kg of the pulverized product. Then, ultrasonic extraction was performed three times for 1 hour by using an ultrasonic wave extractor. The supernatant extract was filtered with Advantec No. 2 (110 mm) filter paper to remove insoluble matter, and then concentrated under reduced pressure at 45 ° C with a condenser equipped with a cooling condenser. To completely remove the solvent of the concentrated extract, 100 mL of purified water was added to suspend it, and 146.4 g of the extract was obtained using a freeze dryer (yield: 14.6%).

Manufacturing example  1-2. Out  Preparation of extract

Curcuma (Scientific name: Curcuma) zedoaria , product name: Curcumae Rhizoma) was prepared by the following method. Commercially available outlets were obtained and pulverized, and then 10 L of 70% ethanol was added to 1 kg of the pulverized product. Then, ultrasonic extraction was performed three times for 1 hour by using an ultrasonic wave extractor. The supernatant extract was filtered with Advantec No. 2 (110 mm) filter paper to remove insoluble matter, and then concentrated under reduced pressure at 45 ° C with a condenser equipped with a cooling condenser. To completely remove the solvent of the concentrated extract, 500 mL of purified water was added to suspend the suspension, and 41.43 g of an extract was obtained (yield: 4.14%) using a freeze dryer.

Example  1. The prostate of the extract Effect on hypertrophy  analysis

Example  1-1. Measuring prostate weight

Since the weight gain of the prostate gland is one of the major symptoms of enlarged prostate gland, the following experiment was conducted to analyze the effect of each extract on enlargement of the prostate gland.

Male SD rats (Sprague-Dawley rats, Orient Bio) 200 to 220 g were purged for one week, and then 6 rats per group were used for the experiment.

Control group with hypertrophy of prostate was prepared by subcutaneously injecting 10 ㎎ / ㎏ of TP (testosterone propionate) for 4 weeks.

The experimental group treated with each extract was prepared by orally administering the mixture of the extract of Mulberry, Mulberry Extract, or the mixture of Mulberry and Mulberry (1: 1) prepared in Example 1 at 100 mg / kg for 4 weeks before TP injection . The mixture was prepared by mixing the extracts of the extracts and the extracts with a solvent immediately before administration.

A positive control group treated with finasteride, a 5α-reductase inhibitor used as a treatment for benign prostatic hyperplasia, was prepared by orally administering pinasteride at 10 mg / kg.

In normal control, corn oil was injected subcutaneously.
