The invention discloses a method and application for extracting polysaccharides from insects of the family Spirulinidae, which has the activity of warming kidney and strengthening yang. The steps are: A. drying and crushing insect bodies of Spirulinidae, refluxing extraction with petroleum ether, filtering and liquid-solid separation; getting rid of oil residue; B. wiping the residue dry, refluxing extraction with distilled water, filtering, merging filtrate, concentrating and obtaining total water extracts; Dilute the total extract of water with distilled water, precipitate polysaccharides with alcohol solution, stir it up side by side, filter it up and filtrate to obtain insect polysaccharide and alcohol precipitate. D, dilute and dissolve the polysaccharide and alcohol precipitates, and separate them with DEAE dextran gel cellulose column chromatography, then wash nine distilled water insects and Sodium Chloride Solution to obtain polysaccharides. It also involves the application of polysaccharides in the preparation of drugs for the treatment or prevention of Yang deficiency, impotence and erectile dysfunction. The method is easy to operate and the purity of polysaccharides is up to 95%. The polysaccharides have strong functions of warming kidney and strengthening yang, resisting fatigue and restoring immunity.

技术介绍
勃起功能障碍是男性最常见的性功能障碍之一,目前的研究认为年龄是勃起功能障碍相关危险因素中最强的独立因素。男性勃起是一个复杂的过程,涉及大脑、激素、情感、神经、肌肉、血管等多方面问题。九香虫为半翅目蝽科九香虫亚科昆虫九香虫AspongopuschinensisDallas的干燥体,别名黑兜虫、瓜黑蝽、臭屁虫、屁巴虫等,为中国特有种。《中国药典》(2015年版)记载九香虫具有理气止痛,温中助阳的功效,用于胃寒胀痛,肝胃气痛,肾虚阳痿,腰膝酸痛。始载于《本草纲目》:“咸温无毒,用于膈脘滞气,脾肾亏损,壮者元阳”。《本草新编》中记载:“虫中之至佳者,亦兴阳之物,以扶衰弱最宜”。民间更是有:“有钱人吃鹿茸,没钱人吃屁巴虫”之说。虽然九香虫的壮阳功效屡有记载,但对其壮阳功效的实验研究未见报道。结合壮阳行为与机体的疲劳密切相关,本专利技术目的提供 ...
