对4个不同来源人工蛹虫草菌株进行平板试验,在培养条件相同情况下,观察比较其生长情况;对相同菌龄不同菌株菌丝体所含虫草素进行超声波提取。结果表明:峰面积与虫草素含量呈良好的线性关系,精密度高,其中菌株YJ113菌丝体虫草素含量最高,为0.505%,其次为菌株YJ111、YJ114,最低的是YJ112,仅0.097%;菌丝湿重依次为YJ113>YJ111>YJ114>YJ112;不同蛹虫草菌株菌丝湿重与其虫草素含量呈正相关关系。 Four different sources of artificial Cordyceps militaris strains were tested in the same culture conditions, the growth was observed and compared; Cordyceps sinensis contained in different strains of the same strain of different strains were ultrasonically extracted. The results showed that: peak area and cordycepin content showed a good linear relationship, high precision, of which strain YJ11  3 mycelia cordycepin content was the highest, 0.505%, followed by strain YJ11  1, YJ11  4, the lowest is YJ11  2, only 0.097%; mycelial wet weight followed by YJ11  3> YJ11  1> YJ11  4> YJ11  2; different cordyceps strains of mycelium wet weight and its cordycepin content was positively correlated.
