青海产天然冬虫夏草的提取物 CsBN 能降低血清胆固醇和甘油三酯含量、增加心肌和脑对(86)Rb 的摄取,并有抗缺氧和镇静作用。从其分离得到的虫草菌经发酵培养,所得菌丝体按同法提取之制剂 CsB 与 CsBN 作用基本相同而效果更强。但对血小板,CsBN 能引起聚集而 CsB 却抑制聚集。 CsBN, an extract of natural Cordyceps sinensis produced in Qinghai, can reduce serum cholesterol and triglyceride levels, increase myocardial and brain uptake of (86)Rb, and have anti-hypoxia and sedative effects. After the isolated Cordyceps sinensis was fermented and cultured, the mycelium obtained by the same method was substantially the same as CsB and CsBN, and the effect was stronger. However, for platelets, CsBN can cause aggregation while CsB inhibit aggregation.
