Application of dendrobium polysaccharide in preparation of drugs for prevention and/or treatment of benign prostatic hyperplasia

The invention discloses an application of dendrobium polysaccharide in the preparation of drugs for prevention and/or treatment of benign prostatic hyperplasia. The dendrobium polysaccharide has obvious therapeutic effect and no toxic and side effects, which can improve the antioxidant capacity of prostate and testes, restore normal expression of key genes of steroid synthesis in leydig cells of benign prostatic hyperplasis, inhibit the expression of 5 alpha-reductase gene in the benign prostatic hyperplasia tissue and effectively treats benign prostatic hyperplasia, especially benign prostatic hyperplasia induced by exogenous androgen. The dendrobium polysaccharide with wide source of raw materials is simple in extraction and purification method, high in sugar content and suitable for large-scale production and popularization and has a good prospect in the preparation and/or treatment of prostate hyperplasia. 本发明公开了石斛多糖在制备预防和/或治疗前列腺增生药物中的应用。所述的石斛多糖的治疗效果明显，无毒、副作用，可以提高前列腺和睾丸的抗氧化能力，恢复前列腺增生睾丸间质细胞类固醇合成关键基因的正常表达，并
