Embodiment 1

[0021] Effect of embodiment 1Rg1 on mouse sexual behavior

[0022] Before the experiment, the mice were trained, selected, and grouped so that the sexual behavior experience and mating background of the mice in each group were basically the same. Rg1, 10, 5, and 25 mg / kg were injected intraperitoneally once every morning, and the female mice were placed in the male mice at night. In the cage, observe its sexual behavior that is straddle (mounting) and mating (mating) times, the result proves that about 2 weeks after administration of Rg1, the mouse's sexual behavior is obviously improved, the results are shown in Figure 1a with 1b .

Embodiment 2

[0023] The influence of embodiment 2 on the relaxing effect of cavernous body

[0024] Three mechanisms have been shown to be involved in the regulation of the tone of the postcavernosal spiral arteries, namely adrenergic, cholinergic and nonadrenergic, noncholinergic (NANC), the latter being considered the host mechanism for relaxation of cavernous vascular smooth muscle, NO is the nerve mediator of NANC. NO acts on guanylate cyclase (GC) to form a NO-GC complex, and combines with the porphyrin part of the enzyme, resulting in a change in configuration and activation of GC, thereby making the cell A large amount of cGMP is formed, which is the NO-cGMP pathway that is closely related to the erectile function of the genitals. Therefore, we observed the effects of Rg1 on the relaxation of the cavernous body, the accumulation of cGMP and the release of NO in the cavernous body.

[0025] We used methylcholine (MCH) as a tool drug for endogenous NO release to observe the effect of ...

Embodiment 3

[0044] PDB5 (type 5 PDE) in the cyclic nucleotide phosphodiesterase (PDE) family is closely related to the reproductive system. It is mainly distributed in the cavernous tissue and platelets of animals, with cGMP as the specific substrate, and GTP in the Under the action of GC, cGMP is formed, and cGMP is hydrolyzed into 5'GMP by PDEs, so the inhibition of PDEs can cause the accumulation of cGMP in the cavernous body, which in turn leads to dilation of the cavernous blood vessels and penile erection.

Abstract

The invention relates to a novel use of ginsenoside Rg1, especially the use in preventing or treating male sexual dysfunction such as ejection dysfunction.

Description

field of invention [0001] The present invention relates to the new use of ginsenoside Rg1, especially the use in preventing or treating male sexual dysfunction such as erectile dysfunction. Background technique [0002] Ginsenoside Rg1 is a known chemical monomer present in many plants such as ginseng. Its structure and relevant biological activities have been reported in relevant textbooks or published literature. However, the use of ginsenoside Rg1 in the prevention and / or treatment of male sexual function has not been reported so far. Contents of the invention [0003] The inventors now find that ginsenoside Rg1 inhibits phosphodiester ester V (PDE v ) to increase the concentration of CGMP, thereby promoting the erectile function of the cavernous body. [0004] Therefore, the first aspect of the present invention relates to the use of ginsenoside Rg1 in the preparation of products for preventing and / or treating sexual dysfunction. [0005] Another aspect of the pres...
