摘要
链霉素 ２３７８菌株所产生的抗生物质对苜蓿（Ａｐｈｉｓ ｍｅｄｉｃａｇ６ｎｉｓ）有较强的触杀作用。活性物质经分离纯化和紫外、红外吸收光谱，质谱及核磁共振谱分析，发现该活性物质与已知抗生素 Ａｃｔｉｎｏｐｙｒｏｎｅｓ Ａ为同一物质。
The antibiotic substance produced by 2378 strain streptomyces showed strongly cantactal activities against Aphis medicagenis. The active substance was isolated and purified and analyzed with UV absorption, IR absorption, Mas and NMR spectra. The results have shown that it is same as Actinopyrones A.
