Embodiment 1
[0068] Example 1 Preparation and structure identification of the compound of the present invention
[0069] 1. Extraction and separation
[0070] The coarse powder of spider odor rhizome (6kg) was extracted by percolation with 95% ethanol as the solvent, 30L of percolate was collected, and concentrated under reduced pressure to obtain 1500g of total extract. The total extract was dispersed in 500ml of water, and then extracted with petroleum ether (60~90℃), ethyl acetate and n-butanol. After the solvent was recovered under reduced pressure, 290g of petroleum ether (60~90℃) extract was obtained, which was extracted with ethyl acetate. 130g, 200g n-butanol extract.
[0071] (1) Further separation of petroleum ether extract
[0072] 100g of petroleum ether (60-90°C) extract was subjected to silica gel column chromatography (petroleum ether→petroleum ether / ethyl acetate→ethyl acetate→acetone gradient elution), and crudely divided into 204 parts.

Embodiment 2
[0099] Example 2 Preparation of an anti-benign prostatic hyperplasia capsule:
[0100] Take 1kg of compound A and 6kg of compound B, add an appropriate amount of starch, mix uniformly, dry granulate, sizing and sizing into capsules to obtain.
[0101] The following activity test proves the beneficial effects of the present invention.
experiment example 2
[0105] Experimental Example 2 Compound B of the present invention (PE116 # ) Inhibition of 5α-reductase activity
[0106] The experiment method is the same as experiment example 1.
[0107]
[0108]
[0109] The result shows that the sample PE116 # Shows positive, with clear activity.
[0110] The above results show that the petroleum ether part, the ethyl acetate part and the two monomer structure (compound A and compound B) components significantly inhibit the formation of DHT.
