    摘要: An animal growth promoter, efomycin G, is obtained by culturing Streptomycetes strain BS 1261. Efomycin G has the following properties:(a) The empirical formula: C.sub.53 H.sub.86 O.sub.18(b) The mass spectrum (fast atom bombardment) Molecular weight+Na.sup.+ : 1033(c) The .sup.1 H-nuclear magnetic resonance spectrum, stated in parts per million, shown in FIG. 1.(d) The .sup.13 C-nuclear magnetic resonance spectrum, stated in parts per million shown in FIG. 2, with chemical shifts of the CC-NMR signals as follows:______________________________________ 170.0 77.9 65.9 32.9 7.0 145.4 73.4 48.5 19.4 144.7 71.2 43.6 19.1 131.9 70.6 41.9 16.8 121.1 70.1 41.1 16.7 99.6 69.9 38.8 15.1 99.5 66.9 38.5 13.4 93.6 66.5 36.2 9.0 93.3 66.4 33.0 8.9 ______________________________________ (ppm values are relative to tetramethylsilane at 0 ppm) (e) A UV absorption maximum at 251-254 nm in methanolic solution(f) The structure according to FIG. 3.
