| 中文摘要: |
| 以天然蝉花Cordyceps cicadae做对比,对一株蝉拟青霉Paecilomyces cicadae菌株发酵菌丝体的化学成分进行了分析,包括粗成分、生物活性成分、无机元素、氨基酸、脂肪酸等。结果表明:蝉拟青霉菌丝体中虫草多糖的含量为33.2mg/g,甘露醇的含量为78.9mg/g,麦角甾醇的含量为0.6256mg/g,腺苷的含量为1.0620mg/g,钙、铁、锌、硒和锰微量元素的含量分别为5187.59μg/g、207.23μg/g、41.93μg/g、0.087μg/g和28.24μg/g,18种氨基酸齐全,不饱和脂肪酸是优势脂肪酸,以亚麻油酸、油酸为主,其相对含量分别为53.91%和20.63%,与天然蝉花相比,发酵菌丝体中虫草多糖、甘露醇、麦角甾醇、腺苷、氨基酸总量、必需氨基酸总量和不饱和脂肪酸的含量明显高于后者,其它化学成分和天然蝉花中相应成分基本一致。 |

| This study analysed the proximate compositions, contents of the bioactive ingredients, amino acids, inorganic elements and fatty acids in the mycelia of Paecilomyces cicadae and fruit body of Cordyceps cicadae. The results showed that in mycelia of Paecilomyces cicadae the content of Cordyceps polysaccharide, mannitol, ergosterol, and adenosine was 33.2 mg/g, 78.9 mg/g, 0.6256 mg/g, and 1.0620 mg/g respectively. The content of microelements such as Ca, Fe, Zn, Se, and Mn was 5187.59 μg/g 207.23 μg/g, 41.93 μg/g and 0.087 μg/g respectively.It was also found that there were linoleic acid and octadecenoic acid,which accounted for 53.91% and 20.63% respectively.Compared with Cordyceps cicadae,the contents of Cordyceps polysaccharide,mannitol,ergosterol,adenine,total amino acid,total necessary amino acid and unsaturated fatty acid in the mycelia of Paecilomyces cicadae were higher than those of Cordyceps cicadae.Other chemical compositions were similar to those in Cordyceps cicadae. |
