Homoalanosine having a herbicidal activity was isolated from the culture filtrate of a soil isolate SC-1688 which was classified as Streptomyces galilaeus. The chemical structure of homoalanosine was determined to be L-2-amino-4-nitrosohydroxyaminobutyric acid by analyses of spectral and biological data. The antibiotic has high herbicidal activity at low concentrations against especially common cocklebur and ladysthumb among the tested weeds and crops. Foliar application of this antibiotic inhibited the growth of roots and buds. This result indicated that homoalanosine had a systemic herbicidal activity.
从一株被归类为加利利链霉菌的土壤分离物SC - 1688的培养滤液中分离出具有除草活性的高丙氨酸。通过光谱和生物学数据分析，确定高丙氨酸的化学结构为L - 2 - 氨基 - 4 - 亚硝基羟氨基丁酸。该抗生素在低浓度下对测试的杂草和作物中的特别是常见的苍耳和萹蓄具有高除草活性。叶面施用这种抗生素抑制了根和芽的生长。这一结果表明高丙氨酸具有内吸性除草活性。
