Abstract
Two kinds of toxins were demonstrated in the culture filtrate of H. sativum, and were called 'M' and 'D' toxins. The lettuce bioassay indicated that D-toxin caused less root growth inhibition than M-toxin. Chemical analysis indicated that M-toxin was a very unusual small peptide. D-toxin was shown to have chemical characteristics similar to helminthosporal based on ultraviolet, proton nuclear magnetic resonance and mass spectra. D-toxin was composed of at least two isomers.
H. sativum 배양액에서 두가지 종류의 식물독소물질이 검출되었으며, 이들을 M-toxin과 D-toxin으로 명명하였다. Lettuce 식물반응결과는 D-toxin 보다 뿌리성장의 저해작용이 적었다. 화학분석결과 M-toxin은 특별히 작은 peptid로 되어 있었다. D-toxin는 Helrninthosporal와 화학적 성질이 비슷하였으나 같지는 않았다. 이는 UV, proton NMR와 질량분석기의 기본 자료인 결과이며, D-toxin은 적어도 두개의 isomers로 되어 있었다.
