1. Thymine and the objective product, 2'-deoxyadenosine, were enzymatically transferred from thymidine and adenine by Brevibacterium acetylium. 胸苷和腺嘌呤在乙酰短杆菌作用下转化成胸腺嘧啶和目标产物2’-脱氧腺苷。
2. deoxyadenosine is the first nucleoside antibiotic separated from epiphyte, it has many pharmacological activities. 虫草素第一个从真菌中分离出来的核苷类抗菌素，它具有多种药理活性作用。
3. In international market, the price of 3'-deoxyadenosine is very expensive. 在国际市场上，虫草素的价格非常昂贵。
4. Thymine and the objective product, 2'-deoxyadenosine, were enzymatically transferred from thymidine and adenine by Brevibacterium acetylium. 胸苷和腺嘌呤在乙酰短杆菌作用下转化成胸腺嘧啶和目标产物2’-脱氧腺苷。
5. The analysis of the extracted crystal of Cordyceps Militaris and standard discriminated by NMR proved that the crystal is Cordycepin (3'-Deoxyadenosine). 用超导核磁共振法（NMR）对自制虫草素结晶和标准品进行鉴定分析结果表明：自制结晶为虫草素（3′-脱氧腺苷）。
